2023/11/28 - Amazon Simple Storage Service - 2 new15 updated api methods
Changes Adds support for S3 Express One Zone.
Creates a session that establishes temporary security credentials to support fast authentication and authorization for the Zonal endpoint APIs on directory buckets. For more information about Zonal endpoint APIs that include the Availability Zone in the request endpoint, see S3 Express One Zone APIs in the Amazon S3 User Guide.
To make Zonal endpoint API requests on a directory bucket, use the CreateSession API operation. Specifically, you grant s3express:CreateSession permission to a bucket in a bucket policy or an IAM identity-based policy. Then, you use IAM credentials to make the CreateSession API request on the bucket, which returns temporary security credentials that include the access key ID, secret access key, session token, and expiration. These credentials have associated permissions to access the Zonal endpoint APIs. After the session is created, you don’t need to use other policies to grant permissions to each Zonal endpoint API individually. Instead, in your Zonal endpoint API requests, you sign your requests by applying the temporary security credentials of the session to the request headers and following the SigV4 protocol for authentication. You also apply the session token to the x-amz-s3session-token request header for authorization. Temporary security credentials are scoped to the bucket and expire after 5 minutes. After the expiration time, any calls that you make with those credentials will fail. You must use IAM credentials again to make a CreateSession API request that generates a new set of temporary credentials for use. Temporary credentials cannot be extended or refreshed beyond the original specified interval.
If you use Amazon Web Services SDKs, SDKs handle the session token refreshes automatically to avoid service interruptions when a session expires. We recommend that you use the Amazon Web Services SDKs to initiate and manage requests to the CreateSession API. For more information, see Performance guidelines and design patterns in the Amazon S3 User Guide.
To obtain temporary security credentials, you must create a bucket policy or an IAM identity-based policy that grants s3express:CreateSession permission to the bucket. In a policy, you can have the s3express:SessionMode condition key to control who can create a ReadWrite or ReadOnly session. For more information about ReadWrite or ReadOnly sessions, see x-amz-create-session-mode. For example policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.
To grant cross-account access to Zonal endpoint APIs, the bucket policy should also grant both accounts the s3express:CreateSession permission.

Request Syntax
client.create_session(
SessionMode='ReadOnly'|'ReadWrite',
Bucket='string'
)
string
Specifies the mode of the session that will be created, either ReadWrite or ReadOnly. By default, a ReadWrite session is created. A ReadWrite session is capable of executing all the Zonal endpoint APIs on a directory bucket. A ReadOnly session is constrained to execute the following Zonal endpoint APIs: GetObject, HeadObject, ListObjectsV2, GetObjectAttributes, ListParts, and ListMultipartUploads.
string
[REQUIRED]
The name of the bucket that you create a session for.

Response Structure
(dict) --
Credentials (dict) --
The established temporary security credentials for the created session..
AccessKeyId (string) --
A unique identifier that's associated with a secret access key. The access key ID and the secret access key are used together to sign programmatic Amazon Web Services requests cryptographically.
SecretAccessKey (string) --
A key that's used with the access key ID to cryptographically sign programmatic Amazon Web Services requests. Signing a request identifies the sender and prevents the request from being altered.
SessionToken (string) --
A part of the temporary security credentials. The session token is used to validate the temporary security credentials.
Expiration (datetime) --
Temporary security credentials expire after a specified interval. After temporary credentials expire, any calls that you make with those credentials will fail. So you must generate a new set of temporary credentials. Temporary credentials cannot be extended or refreshed beyond the original specified interval.
Returns a list of all Amazon S3 directory buckets owned by the authenticated sender of the request. For more information about directory buckets, see Directory buckets in the Amazon S3 User Guide.
You must have the s3express:ListAllMyDirectoryBuckets permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

{'StorageClass': {'EXPRESS_ONEZONE'}}
Creates a copy of an object that is already stored in Amazon S3.
You can copy individual objects between general purpose buckets, between directory buckets, and between general purpose buckets and directory buckets.
Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.
All CopyObject requests must be authenticated and signed by using IAM credentials (access key ID and secret access key for the IAM identities). All headers with the x-amz- prefix, including x-amz-copy-source, must be signed. For more information, see REST Authentication.
Directory buckets - You must use the IAM credentials to authenticate and authorize your access to the CopyObject API operation, instead of using the temporary security credentials through the CreateSession API operation.
Amazon Web Services CLI or SDKs handles authentication and authorization on your behalf.
Permissions
You must have read access to the source object and write access to the destination bucket.
General purpose bucket permissions - You must have permissions in an IAM policy based on the source and destination bucket types in a CopyObject operation.
If the source object is in a general purpose bucket, you must have s3:GetObject permission to read the source object that is being copied.
If the destination bucket is a general purpose bucket, you must have s3:PubObject permission to write the object copy to the destination bucket.
Directory bucket permissions - You must have permissions in a bucket policy or an IAM identity-based policy based on the source and destination bucket types in a CopyObject operation.
If the source object that you want to copy is in a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to read the object. By default, the session is in the ReadWrite mode. If you want to restrict the access, you can explicitly set the s3express:SessionMode condition key to ReadOnly on the copy source bucket.
If the copy destination is a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to write the object to the destination. The s3express:SessionMode condition key can't be set to ReadOnly on the copy destination bucket.
For example policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.
Response and special errors
When the request is an HTTP 1.1 request, the response is chunk encoded. When the request is not an HTTP 1.1 request, the response would not contain the Content-Length. You always need to read the entire response body to check if the copy succeeds. to keep the connection alive while we copy the data.
If the copy is successful, you receive a response with information about the copied object.
A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. A 200 OK response can contain either a success or an error.
If the error occurs before the copy action starts, you receive a standard Amazon S3 error.
If the error occurs during the copy operation, the error response is embedded in the 200 OK response. For example, in a cross-region copy, you may encounter throttling and receive a 200 OK response. For more information, see Resolve the Error 200 response when copying objects to Amazon S3. The 200 OK status code means the copy was accepted, but it doesn't mean the copy is complete. Another example is when you disconnect from Amazon S3 before the copy is complete, Amazon S3 might cancel the copy and you may receive a 200 OK response. You must stay connected to Amazon S3 until the entire response is successfully received and processed. If you call this API operation directly, make sure to design your application to parse the content of the response and handle it appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply error handling per your configuration settings (including automatically retrying the request as appropriate). If the condition persists, the SDKs throw an exception (or, for the SDKs that don't use exceptions, they return an error).
Charge
The copy request charge is based on the storage class and Region that you specify for the destination object. The request can also result in a data retrieval charge for the source if the source storage class bills for data retrieval. For pricing information, see Amazon S3 pricing.

string
The canned access control list (ACL) to apply to the object.
When you copy an object, the ACL metadata is not preserved and is set to private by default. Only the owner has full access control. To override the default ACL setting, specify a new ACL when you generate a copy request. For more information, see Using ACLs.
If the destination bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.
string
[REQUIRED]
The name of the destination bucket.
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az2--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.
Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
string
Specifies the caching behavior along the request/reply chain.
string
Indicates the algorithm that you want Amazon S3 to use to create the checksum for the object. For more information, see Checking object integrity in the Amazon S3 User Guide.
When you copy an object, if the source object has a checksum, that checksum value will be copied to the new object by default. If the CopyObject request does not include this x-amz-checksum-algorithm header, the checksum algorithm will be copied from the source object to the destination object (if it's present on the source object). You can optionally specify a different checksum algorithm to use with the x-amz-checksum-algorithm header. Unrecognized or unsupported values will respond with the HTTP status code 400 Bad Request.
string
Specifies presentational information for the object. Indicates whether an object should be displayed in a web browser or downloaded as a file. It allows specifying the desired filename for the downloaded file.
string
Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.
string
The language the content is in.
string
A standard MIME type that describes the format of the object data.
string
[REQUIRED]
Specifies the source object for the copy operation. The source object can be up to 5 GB. If the source object is an object that was uploaded by using a multipart upload, the object copy will be a single part object after the source object is copied to the destination bucket.
You specify the value of the copy source in one of two formats, depending on whether you want to access the source object through an access point:
For objects not accessed through an access point, specify the name of the source bucket and the key of the source object, separated by a slash (/). For example, to copy the object reports/january.pdf from the general purpose bucket awsexamplebucket, use awsexamplebucket/reports/january.pdf. The value must be URL-encoded. To copy the object reports/january.pdf from the directory bucket awsexamplebucket--use1-az5--x-s3, use awsexamplebucket--use1-az5--x-s3/reports/january.pdf. The value must be URL-encoded.
For objects accessed through access points, specify the Amazon Resource Name (ARN) of the object as accessed through the access point, in the format arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key>. For example, to copy the object reports/january.pdf through access point my-access-point owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf. The value must be URL encoded.
Alternatively, for objects accessed through Amazon S3 on Outposts, specify the ARN of the object as accessed in the format arn:aws:s3-outposts:<Region>:<account-id>:outpost/<outpost-id>/object/<key>. For example, to copy the object reports/january.pdf through outpost my-outpost owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf. The value must be URL-encoded.
If your source bucket versioning is enabled, the x-amz-copy-source header by default identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId query parameter. Specifically, append ?versionId=<version-id> to the value (for example, awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893). If you don't specify a version ID, Amazon S3 copies the latest version of the source object.
If you enable versioning on the destination bucket, Amazon S3 generates a unique version ID for the copied object. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response.
If you do not enable versioning or suspend it on the destination bucket, the version ID that Amazon S3 generates in the x-amz-version-id response header is always null.
string
Copies the object if its entity tag (ETag) matches the specified tag.
If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:
x-amz-copy-source-if-match condition evaluates to true
x-amz-copy-source-if-unmodified-since condition evaluates to false
datetime
Copies the object if it has been modified since the specified time.
If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:
x-amz-copy-source-if-none-match condition evaluates to false
x-amz-copy-source-if-modified-since condition evaluates to true
string
Copies the object if its entity tag (ETag) is different than the specified ETag.
If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:
x-amz-copy-source-if-none-match condition evaluates to false
x-amz-copy-source-if-modified-since condition evaluates to true
datetime
Copies the object if it hasn't been modified since the specified time.
If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:
x-amz-copy-source-if-match condition evaluates to true
x-amz-copy-source-if-unmodified-since condition evaluates to false
datetime
The date and time at which the object is no longer cacheable.
string
Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.
string
Allows grantee to read the object data and its metadata.
string
Allows grantee to read the object ACL.
string
Allows grantee to write the ACL for the applicable object.
string
[REQUIRED]
The key of the destination object.
dict
A map of metadata to store with the object in S3.
(string) --
(string) --
string
Specifies whether the metadata is copied from the source object or replaced with metadata that's provided in the request. When copying an object, you can preserve all metadata (the default) or specify new metadata. If this header isn’t specified, COPY is the default behavior.
General purpose bucket - For general purpose buckets, when you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Amazon S3 condition key examples in the Amazon S3 User Guide.
string
Specifies whether the object tag-set is copied from the source object or replaced with the tag-set that's provided in the request.
The default value is COPY.
string
The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms, aws:kms:dsse). Unrecognized or unsupported values won’t write a destination object and will receive a 400 Bad Request response.
Amazon S3 automatically encrypts all new objects that are copied to an S3 bucket. When copying an object, if you don't specify encryption information in your copy request, the encryption setting of the target object is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with Key Management Service (KMS) keys (SSE-KMS), dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), or server-side encryption with customer-provided encryption keys (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the target object copy.
When you perform a CopyObject operation, if you want to use a different type of encryption setting for the target object, you can specify appropriate encryption-related headers to encrypt the target object with an Amazon S3 managed key, a KMS key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence.
With server-side encryption, Amazon S3 encrypts your data as it writes your data to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see Using Server-Side Encryption in the Amazon S3 User Guide.
string
If the x-amz-storage-class header is not used, the copied object will be stored in the STANDARD Storage Class by default. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class.
You can use the CopyObject action to change the storage class of an object that is already stored in Amazon S3 by using the x-amz-storage-class header. For more information, see Storage Classes in the Amazon S3 User Guide.
Before using an object as a source object for the copy operation, you must restore a copy of it if it meets any of the following conditions:
The storage class of the source object is GLACIER or DEEP_ARCHIVE.
The storage class of the source object is INTELLIGENT_TIERING and it's S3 Intelligent-Tiering access tier is Archive Access or Deep Archive Access.
For more information, see RestoreObject and Copying Objects in the Amazon S3 User Guide.
string
If the destination bucket is configured as a website, redirects requests for this object copy to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. This value is unique to each object and is not copied when using the x-amz-metadata-directive header. Instead, you may opt to provide this header in combination with the x-amz-metadata-directive header.
string
Specifies the algorithm to use when encrypting the object (for example, AES256).
When you perform a CopyObject operation, if you want to use a different type of encryption setting for the target object, you can specify appropriate encryption-related headers to encrypt the target object with an Amazon S3 managed key, a KMS key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence.
string
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded. Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
string
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.
string
Specifies the KMS ID (Key ID, Key ARN, or Key Alias) to use for object encryption. All GET and PUT requests for an object protected by KMS will fail if they're not made via SSL or using SigV4. For information about configuring any of the officially supported Amazon Web Services SDKs and Amazon Web Services CLI, see Specifying the Signature Version in Request Authentication in the Amazon S3 User Guide.
string
Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value must be explicitly added to specify encryption context for CopyObject requests.
boolean
Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Key Management Service (KMS) keys (SSE-KMS). If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object.
Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS. Specifying this header with a COPY action doesn’t affect bucket-level settings for S3 Bucket Key.
For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.
string
Specifies the algorithm to use when decrypting the source object (for example, AES256).
If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.
string
Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be the same one that was used when the source object was created.
If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.
string
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.
If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.
string
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.
string
The tag-set for the object copy in the destination bucket. This value must be used in conjunction with the x-amz-tagging-directive if you choose REPLACE for the x-amz-tagging-directive. If you choose COPY for the x-amz-tagging-directive, you don't need to set the x-amz-tagging header, because the tag-set will be copied from the source object directly. The tag-set must be encoded as URL Query parameters.
The default value is the empty value.
string
The Object Lock mode that you want to apply to the object copy.
datetime
The date and time when you want the Object Lock of the object copy to expire.
string
Specifies whether you want to apply a legal hold to the object copy.
string
The account ID of the expected destination bucket owner. If the account ID that you provide does not match the actual owner of the destination bucket, the request fails with the HTTP status code 403 Forbidden (access denied).
string
The account ID of the expected source bucket owner. If the account ID that you provide does not match the actual owner of the source bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

Creates a new S3 bucket. To create a bucket, you must set up Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.
There are two types of buckets: general purpose buckets and directory buckets. For more information about these bucket types, see Creating, configuring, and working with Amazon S3 buckets in the Amazon S3 User Guide.
General purpose bucket permissions - In addition to the s3:CreateBucket permission, the following permissions are required in a policy when your CreateBucket request includes specific headers:
Access control lists (ACLs) - In your CreateBucket request, if you specify an access control list (ACL) and set it to public-read, public-read-write, authenticated-read, or if you explicitly specify any other custom ACLs, both s3:CreateBucket and s3:PutBucketAcl permissions are required. In your CreateBucket request, if you set the ACL to private, or if you don't specify any ACLs, only the s3:CreateBucket permission is required.
Object Lock - In your CreateBucket request, if you set x-amz-bucket-object-lock-enabled to true, the s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.
S3 Object Ownership - If your CreateBucket request includes the x-amz-object-ownership header, then the s3:PutBucketOwnershipControls permission is required.
S3 Block Public Access - If your specific use case requires granting public access to your S3 resources, you can disable Block Public Access. Specifically, you can create a new bucket with Block Public Access enabled, then separately call the DeletePublicAccessBlock API. To use this operation, you must have the s3:PutBucketPublicAccessBlock permission. For more information about S3 Block Public Access, see Blocking public access to your Amazon S3 storage in the Amazon S3 User Guide.
Directory bucket permissions - You must have the s3express:CreateBucket permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.
Directory buckets - The HTTP Host header syntax is s3express-control.region.amazonaws.com.

General purpose buckets - For information about bucket naming restrictions, see Bucket naming rules in the Amazon S3 User Guide.
Directory buckets - When you use this operation with a directory bucket, you must use path-style requests in the format https://s3express-control.region_code.amazonaws.com/bucket-name ``. Virtual-hosted-style requests aren't supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must also follow the format ``bucket_base_name--az_id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az2--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide
dict
The configuration information for the bucket.
LocationConstraint (string) --
Specifies the Region where the bucket will be created. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket in the Amazon S3 User Guide.
If you don't specify a Region, the bucket is created in the US East (N. Virginia) Region (us-east-1) by default.
Location (dict) --
Specifies the location where the bucket will be created.
For directory buckets, the location type is Availability Zone.
Type (string) --
The type of location where the bucket will be created.
Name (string) --
The name of the location where the bucket will be created.
For directory buckets, the AZ ID of the Availability Zone where the bucket will be created. An example AZ ID value is usw2-az2.
Bucket (dict) --
Specifies the information about the bucket that will be created.
DataRedundancy (string) --
The number of Availability Zone that's used for redundancy for the bucket.
Type (string) --
The type of bucket.
string
Allows grantee the read, write, read ACP, and write ACP permissions on the bucket.
string
Allows grantee to list the objects in the bucket.
string
Allows grantee to read the bucket ACL.
string
Allows grantee to create new objects in the bucket.
For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects.
string
Allows grantee to write the ACL for the applicable bucket.
boolean
Specifies whether you want S3 Object Lock to be enabled for the new bucket.
string
The container element for object ownership for a bucket's ownership controls.
BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.
ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.
BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or specify bucket owner full control ACLs (such as the predefined bucket-owner-full-control canned ACL or a custom ACL in XML format that grants the same permissions).
By default, ObjectOwnership is set to BucketOwnerEnforced and ACLs are disabled. We recommend keeping ACLs disabled, except in uncommon use cases where you must control access for each object individually. For more information about S3 Object Ownership, see Controlling ownership of objects and disabling ACLs for your bucket in the Amazon S3 User Guide.

This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart). You also include this upload ID in the final request to either complete or abort the multipart upload request. For more information about multipart uploads, see Multipart Upload Overview in the Amazon S3 User Guide.
If you have configured a lifecycle rule to abort incomplete multipart uploads, the created multipart upload must be completed within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Configuration.
For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4) in the Amazon S3 User Guide.
Permissions
General purpose bucket permissions - For information about the permissions required to use the multipart upload API, see Multipart upload and permissions in the Amazon S3 User Guide. To perform a multipart upload with encryption by using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions and Protecting data using server-side encryption with Amazon Web Services KMS in the Amazon S3 User Guide.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.
Encryption
General purpose buckets - Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. Amazon S3 automatically encrypts all new objects that are uploaded to an S3 bucket. When doing a multipart upload, if you don't specify encryption information in your request, the encryption setting of the uploaded parts is set to the default encryption configuration of the destination bucket. By default, all buckets have a base level of encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the destination bucket has a default encryption configuration that uses server-side encryption with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C), Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the uploaded parts. When you perform a CreateMultipartUpload operation, if you want to use a different type of encryption setting for the uploaded parts, you can request that Amazon S3 encrypts the object with a different encryption key (such as an Amazon S3 managed key, a KMS key, or a customer-provided key). When the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the CreateMultipartUpload request.
Use KMS keys (SSE-KMS) that include the Amazon Web Services managed key ( aws/s3) and KMS customer managed keys stored in Key Management Service (KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request.
x-amz-server-side-encryption
x-amz-server-side-encryption-aws-kms-key-id
x-amz-server-side-encryption-context
For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys in the Amazon S3 User Guide.
Use customer-provided encryption keys (SSE-C) – If you want to manage your own encryption keys, provide all the following headers in the request.
x-amz-server-side-encryption-customer-algorithm
x-amz-server-side-encryption-customer-key
x-amz-server-side-encryption-customer-key-MD5
For more information about server-side encryption with customer-provided encryption keys (SSE-C), see Protecting data using server-side encryption with customer-provided encryption keys (SSE-C) in the Amazon S3 User Guide.
Directory buckets -For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) ( AES256) is supported.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

string
The canned ACL to apply to the object. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL in the Amazon S3 User Guide.
By default, all objects are private. Only the owner has full access control. When uploading an object, you can grant access permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the new object. For more information, see Using ACLs. One way to grant the permissions using the request headers is to specify a canned ACL with the x-amz-acl request header.
string
[REQUIRED]
The name of the bucket where the multipart upload is initiated and where the object is uploaded.
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az2--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.
Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.

Object key for which the multipart upload is to be initiated.
dict
A map of metadata to store with the object in S3.
(string) --
(string) --
string
The server-side encryption algorithm used when you store this object in Amazon S3 (for example, AES256, aws:kms).
string
By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide.
string
If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.
string
Specifies the algorithm to use when encrypting the object (for example, AES256).
string
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
string
Specifies the 128-bit MD5 digest of the customer-provided encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.
string
Specifies the ID (Key ID, Key ARN, or Key Alias) of the symmetric encryption customer managed key to use for object encryption.
string
Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.
boolean
Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Key Management Service (KMS) keys (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.
Specifying this header with an object action doesn’t affect bucket-level settings for S3 Bucket Key.
string
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.
string
The tag-set for the object. The tag-set must be encoded as URL Query parameters.
string
Specifies the Object Lock mode that you want to apply to the uploaded object.
datetime
Specifies the date and time when you want the Object Lock to expire.
string
Specifies whether you want to apply a legal hold to the uploaded object.
string
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).
string
Indicates the algorithm that you want Amazon S3 to use to create the checksum for the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

However, if there are two or more rules with the same destination bucket, then objects will be replicated according to the rule with the highest priority. The higher the number, the higher the priority.
For more information, see Replication in the Amazon S3 User Guide.
Prefix (string) --
An object key name prefix that identifies the object or objects to which the rule applies. The maximum prefix length is 1,024 characters. To include all objects in a bucket, specify an empty string.
Filter (dict) --
A filter that identifies the subset of objects to which the replication rule applies. A Filter must specify exactly one Prefix, Tag, or an And child element.

The rule applies only to objects that have the tag in their tag set.
Key (string) --
Name of the object key.
Value (string) --
Value of the tag.
And (dict) --
A container for specifying rule filters. The filters determine the subset of objects to which the rule applies. This element is required only if you specify more than one filter. For example:
If you specify both a Prefix and a Tag filter, wrap these filters in an And tag.

Bucket (string) --
The Amazon Resource Name (ARN) of the bucket where you want Amazon S3 to store the results.
Account (string) --
Destination bucket owner account ID. In a cross-account scenario, if you direct Amazon S3 to change replica ownership to the Amazon Web Services account that owns the destination bucket by specifying the AccessControlTranslation property, this is the account ID of the destination bucket owner. For more information, see Replication Additional Configuration: Changing the Replica Owner in the Amazon S3 User Guide.
StorageClass (string) --
The storage class to use when replicating objects, such as S3 Standard or reduced redundancy. By default, Amazon S3 uses the storage class of the source object to create the object replica.
For valid values, see the StorageClass element of the PUT Bucket replication action in the Amazon S3 API Reference.
AccessControlTranslation (dict) --
Specify this only in a cross-account scenario (where source and destination bucket owners are not the same), and you want to change replica ownership to the Amazon Web Services account that owns the destination bucket. If this is not specified in the replication configuration, the replicas are owned by same Amazon Web Services account that owns the source object.
Owner (string) --
Specifies the replica ownership. For default and valid values, see PUT bucket replication in the Amazon S3 API Reference.
EncryptionConfiguration (dict) --

{'StorageClass': {'EXPRESS_ONEZONE'}}
Retrieves an object from Amazon S3.
In the GetObject request, specify the full key name for the object.
General purpose buckets - Both the virtual-hosted-style requests and the path-style requests are supported. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg, specify the object key name as /photos/2006/February/sample.jpg. For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket, specify the object key name as /examplebucket/photos/2006/February/sample.jpg. For more information about request types, see HTTP Host Header Bucket Specification in the Amazon S3 User Guide.
Directory buckets - Only virtual-hosted-style requests are supported. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket--use1-az5--x-s3, specify the object key name as /photos/2006/February/sample.jpg. Also, when you make requests to this API operation, your requests are sent to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format ``https://bucket_name.s3express-az_id.region.amazonaws.com/key-name ``. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.
Permissions
General purpose bucket permissions - You must have the required permissions in a policy. To use GetObject, you must have the READ access to the object (or version). If you grant READ access to the anonymous user, the GetObject operation returns the object without using an authorization header. For more information, see Specifying permissions in a policy in the Amazon S3 User Guide. If you include a versionId in your request header, you must have the s3:GetObjectVersion permission to access a specific version of an object. The s3:GetObject permission is not required in this scenario. If you request the current version of an object without a specific versionId in the request header, only the s3:GetObject permission is required. The s3:GetObjectVersion permission is not required in this scenario. If the object that you request doesn’t exist, the error that Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found error.
If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Access Denied error.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.
Storage classes
If the object you are retrieving is stored in the S3 Glacier Flexible Retrieval storage class, the S3 Glacier Deep Archive storage class, the S3 Intelligent-Tiering Archive Access tier, or the S3 Intelligent-Tiering Deep Archive Access tier, before you can retrieve the object you must first restore a copy using RestoreObject. Otherwise, this operation returns an InvalidObjectState error. For information about restoring archived objects, see Restoring Archived Objects in the Amazon S3 User Guide.
Directory buckets - For directory buckets, only the S3 Express One Zone storage class is supported to store newly created objects. Unsupported storage class values won't write a destination object and will respond with the HTTP status code 400 Bad Request.
Encryption
Encryption request headers, like x-amz-server-side-encryption, should not be sent for the GetObject requests, if your object uses server-side encryption with Amazon S3 managed encryption keys (SSE-S3), server-side encryption with Key Management Service (KMS) keys (SSE-KMS), or dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS). If you include the header in your GetObject requests for the object that uses these types of keys, you’ll get an HTTP 400 Bad Request error.
Overriding response header values through the request
There are times when you want to override certain response header values of a GetObject response. For example, you might override the Content-Disposition response header value through your GetObject request.
You can override values for a set of response headers. These modified response header values are included only in a successful response, that is, when the HTTP status code 200 OK is returned. The headers you can override using the following query parameters in the request are a subset of the headers that Amazon S3 accepts when you create an object.
The response headers that you can override for the GetObject response are Cache-Control, Content-Disposition, Content-Encoding, Content-Language, Content-Type, and Expires.
To override values for a set of response headers in the GetObject response, you can use the following query parameters in the request.
response-cache-control
response-content-disposition
response-content-encoding
response-content-language
response-content-type
response-expires
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az2--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.
Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
Object Lambda access points - When you use this action with an Object Lambda access point, you must direct requests to the Object Lambda access point hostname. The Object Lambda access point hostname takes the form AccessPointName-AccountId.s3-object-lambda.*Region*.amazonaws.com.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.

{'StorageClass': {'EXPRESS_ONEZONE'}}
Retrieves all the metadata from an object without returning the object itself. This operation is useful if you're interested only in an object's metadata.
GetObjectAttributes combines the functionality of HeadObject and ListParts. All of the data returned with each of those individual calls can be returned with a single call to GetObjectAttributes.
General purpose bucket permissions - To use GetObjectAttributes, you must have READ access to the object. The permissions that you need to use this operation with depend on whether the bucket is versioned. If the bucket is versioned, you need both the s3:GetObjectVersion and s3:GetObjectVersionAttributes permissions for this operation. If the bucket is not versioned, you need the s3:GetObject and s3:GetObjectAttributes permissions. For more information, see Specifying Permissions in a Policy in the Amazon S3 User Guide. If the object that you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found ("no such key") error.
If you don't have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Forbidden ("access denied") error.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.
Encryption
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers to provide the encryption key for the server to be able to retrieve the object's metadata. The headers are:
x-amz-server-side-encryption-customer-algorithm
x-amz-server-side-encryption-customer-key
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.
Directory buckets - S3 Versioning isn't enabled and supported for directory buckets. For this API operation, only the null value of the version ID is supported by directory buckets. You can only specify null to the versionId query parameter in the request.
Conditional request headers
Consider the following when using request headers:
If both of the If-Match and If-Unmodified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 200 OK and the data requested:
If-Match condition evaluates to true.
If-Unmodified-Since condition evaluates to false.
For more information about conditional requests, see RFC 7232.
If both of the If-None-Match and If-Modified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 304 Not Modified:
If-None-Match condition evaluates to false.
If-Modified-Since condition evaluates to true.
For more information about conditional requests, see RFC 7232.

Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
string
[REQUIRED]
The object key.

{'StorageClass': {'EXPRESS_ONEZONE'}}
The HEAD operation retrieves metadata from an object without returning the object itself. This operation is useful if you're interested only in an object's metadata.
A HEAD request has the same options as a GET operation on an object. The response is identical to the GET response except that there is no response body. Because of this, if the HEAD request generates an error, it returns a generic code, such as 400 Bad Request, 403 Forbidden, 404 Not Found, 405 Method Not Allowed, 412 Precondition Failed, or 304 Not Modified. It's not possible to retrieve the exact exception of these error codes.
Request headers are limited to 8 KB in size. For more information, see Common Request Headers.
General purpose bucket permissions - To use HEAD, you must have the s3:GetObject permission. You need the relevant read object (or version) permission for this operation. For more information, see Actions, resources, and condition keys for Amazon S3 in the Amazon S3 User Guide. If the object you request doesn't exist, the error that Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found error.
If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Forbidden error.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.
Encryption
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers to provide the encryption key for the server to be able to retrieve the object's metadata. The headers are:
x-amz-server-side-encryption-customer-algorithm
x-amz-server-side-encryption-customer-key
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide.
If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.
If the specified version is a delete marker, the response returns a 405 Method Not Allowed error and the Last-Modified: timestamp response header.
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.
For more information, see Storage Classes.
RequestCharged (string) --
If present, indicates that the requester was successfully charged for the request.
ReplicationStatus (string) --
Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.
In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object ( GetObject) or object metadata ( HeadObject) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:
If requesting an object from the source bucket, Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication. For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs. Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf, are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.
If requesting an object from a destination bucket, Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created and there is no replica modification replication in progress.
When replicating objects to multiple destination buckets, the x-amz-replication-status header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.
For more information, see Replication.
PartsCount (integer) --
The count of parts this object has. This value is only returned if you specify partNumber in your request and the object was uploaded as a multipart upload.
ObjectLockMode (string) --
The Object Lock mode, if any, that's in effect for this object. This header is only returned if the requester has the s3:GetObjectRetention permission. For more information about S3 Object Lock, see Object Lock.
ObjectLockRetainUntilDate (datetime) --
The date and time when the Object Lock retention period expires. This header is only returned if the requester has the s3:GetObjectRetention permission.
ObjectLockLegalHoldStatus (string) --
Specifies whether a legal hold is in effect for this object. This header is only returned if the requester has the s3:GetObjectLegalHold permission. This header is not returned if the specified version of this object has never had a legal hold applied. For more information about S3 Object Lock, see Object Lock.
{'Uploads': {'StorageClass': {'EXPRESS_ONEZONE'}}}
This operation lists in-progress multipart uploads in a bucket. An in-progress multipart upload is a multipart upload that has been initiated by the CreateMultipartUpload request, but has not yet been completed or aborted.
The ListMultipartUploads operation returns a maximum of 1,000 multipart uploads in the response. The limit of 1,000 multipart uploads is also the default value. You can further limit the number of uploads in a response by specifying the max-uploads request parameter. If there are more than 1,000 multipart uploads that satisfy your ListMultipartUploads request, the response returns an IsTruncated element with the value of true, a NextKeyMarker element, and a NextUploadIdMarker element. To list the remaining multipart uploads, you need to make subsequent ListMultipartUploads requests. In these requests, include two query parameters: key-marker and upload-id-marker. Set the value of key-marker to the NextKeyMarker value from the previous response. Similarly, set the value of upload-id-marker to the NextUploadIdMarker value from the previous response.
For more information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide.
General purpose bucket permissions - For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.
Sorting of multipart uploads in response
General purpose bucket - In the ListMultipartUploads response, the multipart uploads are sorted based on two criteria:
Key-based sorting - Multipart uploads are initially sorted in ascending order based on their object keys.
Time-based sorting - For uploads that share the same object key, they are further sorted in ascending order based on the upload initiation time. Among uploads with the same key, the one that was initiated first will appear before the ones that were initiated later.
Directory bucket - In the ListMultipartUploads response, the multipart uploads aren't sorted lexicographically based on the object keys.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

string
[REQUIRED]
The name of the bucket to which the multipart upload was initiated.
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az2--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.
Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
string
Character you use to group keys.
All keys that contain the same string between the prefix, if specified, and the first occurrence of the delimiter after the prefix are grouped under a single result element, CommonPrefixes. If you don't specify the prefix parameter, then the substring starts at the beginning of the key. The keys that are grouped under CommonPrefixes result element are not returned elsewhere in the response.
string
Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key can contain any Unicode character; however, the XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
string
Specifies the multipart upload after which listing should begin.
integer
Sets the maximum number of multipart uploads, from 1 to 1,000, to return in the response body. 1,000 is the maximum number of uploads that can be returned in a response.
string
Lists in-progress uploads only for those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different grouping of keys. (You can think of using prefix to make groups in the same way that you'd use a folder in a file system.)
string
Together with key-marker, specifies the multipart upload after which listing should begin. If key-marker is not specified, the upload-id-marker parameter is ignored. Otherwise, any multipart uploads for a key equal to the key-marker might be included in the list only if they have an upload ID lexicographically greater than the specified upload-id-marker.
string
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).
string
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

Response Structure
(dict) --
IsTruncated (boolean) --
A flag that indicates whether Amazon S3 returned all of the results that satisfied the search criteria.
Marker (string) --
Indicates where in the bucket listing begins. Marker is included in the response if it was sent with the request.
NextMarker (string) --
When the response is truncated (the IsTruncated element value in the response is true), you can use the key name in this field as the marker parameter in the subsequent request to get the next set of objects. Amazon S3 lists objects in alphabetical order.
Contents (list) --
Metadata about each object returned.
(dict) --
An object consists of data and its descriptive metadata.
Key (string) --
The name that you assign to an object. You use the object key to retrieve the object.
LastModified (datetime) --
Creation date of the object.
ETag (string) --
The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Whether or not it is depends on how the object was created and how it is encrypted as described below:
Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-S3 or plaintext, have ETags that are an MD5 digest of their object data.
Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-C or SSE-KMS, have ETags that are not an MD5 digest of their object data.
If an object is created by either the Multipart Upload or Part Copy operation, the ETag is not an MD5 digest, regardless of the method of encryption. If an object is larger than 16 MB, the Amazon Web Services Management Console will upload or copy that object as a Multipart Upload, and therefore the ETag will not be an MD5 digest.
ChecksumAlgorithm (list) --
The algorithm that was used to create a checksum of the object.
(string) --
Size (integer) --
Size in bytes of the object
StorageClass (string) --
The class of storage used to store the object.
Owner (dict) --

Asia Pacific (Singapore)
Asia Pacific (Sydney)
Asia Pacific (Tokyo)
Europe (Ireland)
South America (São Paulo)
ID (string) --
Container for the ID of the owner.
RestoreStatus (dict) --
Specifies the restoration status of an object. Objects in certain storage classes must be restored before they can be retrieved. For more information about these storage classes and how to work with archived objects, see Working with archived objects in the Amazon S3 User Guide.
IsRestoreInProgress (boolean) --
Specifies whether the object is currently being restored. If the object restoration is in progress, the header returns the value TRUE. For example:
x-amz-optional-object-attributes: IsRestoreInProgress="true"
If the object restoration has completed, the header returns the value FALSE. For example:
x-amz-optional-object-attributes: IsRestoreInProgress="false", RestoreExpiryDate="2012-12-21T00:00:00.000Z"
If the object hasn't been restored, there is no header response.
RestoreExpiryDate (datetime) --
Indicates when the restored copy will expire. This value is populated only if the object has already been restored. For example:
x-amz-optional-object-attributes: IsRestoreInProgress="false", RestoreExpiryDate="2012-12-21T00:00:00.000Z"
Name (string) --
The bucket name.
Prefix (string) --
Keys that begin with the indicated prefix.
Delimiter (string) --
Causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the CommonPrefixes collection. These rolled-up keys are not returned elsewhere in the response. Each rolled-up result counts as only one return against the MaxKeys value.
MaxKeys (integer) --
The maximum number of keys returned in the response body.
CommonPrefixes (list) --
All of the keys (up to 1,000) rolled up in a common prefix count as a single return when calculating the number of returns.
A response can contain CommonPrefixes only if you specify a delimiter.
CommonPrefixes contains all (if there are any) keys between Prefix and the next occurrence of the string specified by the delimiter.
CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix.
For example, if the prefix is notes/ and the delimiter is a slash ( /), as in notes/summer/july, the common prefix is notes/summer/. All of the keys that roll up into a common prefix count as a single return when calculating the number of returns.

{'Contents': {'StorageClass': {'EXPRESS_ONEZONE'}}}
Returns some or all (up to 1,000) of the objects in a bucket with each request. You can use the request parameters as selection criteria to return a subset of the objects in a bucket. A 200 OK response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately. For more information about listing objects, see Listing object keys programmatically in the Amazon S3 User Guide. To get a list of your buckets, see ListBuckets.
General purpose bucket permissions - To use this operation, you must have READ access to the bucket. You must have permission to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.
Sorting order of returned objects
General purpose bucket - For general purpose buckets, ListObjectsV2 returns objects in lexicographical order based on their key names.
Directory bucket - For directory buckets, ListObjectsV2 does not return objects in lexicographical order.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

If present, indicates that the requester was successfully charged for the request.
{'StorageClass': {'EXPRESS_ONEZONE'}}
Lists the parts that have been uploaded for a specific multipart upload.
To use this operation, you must provide the upload ID in the request. You obtain this uploadID by sending the initiate multipart upload request through CreateMultipartUpload.
The ListParts request returns a maximum of 1,000 uploaded parts. The limit of 1,000 parts is also the default value. You can restrict the number of parts in a response by specifying the max-parts request parameter. If your multipart upload consists of more than 1,000 parts, the response returns an IsTruncated field with the value of true, and a NextPartNumberMarker element. To list remaining uploaded parts, in subsequent ListParts requests, include the part-number-marker query string parameter and set its value to the NextPartNumberMarker field value from the previous response.
For more information on multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide.
General purpose bucket permissions - For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide. If the upload was created using server-side encryption with Key Management Service (KMS) keys (SSE-KMS) or dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), you must have permission to the kms:Decrypt action for the ListParts request to succeed.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

{'ReplicationConfiguration': {'Rules': {'Destination': {'StorageClass': {'EXPRESS_ONEZONE'}}}}}
Creates a replication configuration or replaces an existing one. For more information, see Replication in the Amazon S3 User Guide.
Specify the replication configuration in the request body. In the replication configuration, you provide the name of the destination bucket or buckets where you want Amazon S3 to replicate objects, the IAM role that Amazon S3 can assume to replicate objects on your behalf, and other relevant information. You can invoke this request for a specific Amazon Web Services Region by using the aws:RequestedRegion condition key.
A replication configuration must include at least one rule, and can contain a maximum of 1,000. Each rule identifies a subset of objects to replicate by filtering the objects in the source bucket. To choose additional subsets of objects to replicate, add a rule for each subset.
To specify a subset of the objects in the source bucket to apply a replication rule to, add the Filter element as a child of the Rule element. You can filter objects based on an object key prefix, one or more object tags, or both. When you add the Filter element in the configuration, you must also add the following elements: DeleteMarkerReplication, Status, and Priority.
For information about enabling versioning on a bucket, see Using Versioning.
Handling Replication of Encrypted Objects
By default, Amazon S3 doesn't replicate objects that are stored at rest using server-side encryption with KMS keys. To replicate Amazon Web Services KMS-encrypted objects, add the following: SourceSelectionCriteria, SseKmsEncryptedObjects, Status, EncryptionConfiguration, and ReplicaKmsKeyID. For information about replication configuration, see Replicating Objects Created with SSE Using KMS keys.
For information on PutBucketReplication errors, see List of replication-related error codes
Permissions
To create a PutBucketReplication request, you must have s3:PutReplicationConfiguration permissions for the bucket.
By default, a resource owner, in this case the Amazon Web Services account that created the bucket, can perform this operation. The resource owner can also grant others permissions to perform the operation. For more information about permissions, see Specifying Permissions in a Policy and Managing Access Permissions to Your Amazon S3 Resources.

{'StorageClass': {'EXPRESS_ONEZONE'}}
Adds an object to a bucket.
Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. However, Amazon S3 provides features that can modify this behavior:
S3 Object Lock - To prevent objects from being deleted or overwritten, you can use Amazon S3 Object Lock in the Amazon S3 User Guide.
S3 Versioning - When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all versions of the objects. For each write request that is made to the same object, Amazon S3 automatically generates a unique version ID of that object being stored in Amazon S3. You can retrieve, replace, or delete any version of the object. For more information about versioning, see Adding Objects to Versioning-Enabled Buckets in the Amazon S3 User Guide. For information about returning the versioning state of a bucket, see GetBucketVersioning.
General purpose bucket permissions - The following permissions are required in your policies when your PutObject request includes specific headers.
s3:PutObject - To successfully complete the PutObject request, you must always have the s3:PutObject permission on a bucket to add an object to it.
s3:PutObjectAcl - To successfully change the objects ACL of your PutObject request, you must have the s3:PutObjectAcl.
s3:PutObjectTagging - To successfully set the tag-set with your PutObject request, you must have the s3:PutObjectTagging.
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.
Data integrity with Content-MD5
General purpose bucket - To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, Amazon S3 returns an error. Alternatively, when the object's ETag is its MD5 digest, you can calculate the MD5 while putting the object to Amazon S3 and compare the returned ETag to the calculated MD5 value.
Directory bucket - This functionality is not supported for directory buckets.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

string
The canned ACL to apply to the object. For more information, see Canned ACL in the Amazon S3 User Guide.
When adding a new object, you can use headers to grant ACL-based permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. By default, all objects are private. Only the owner has full access control. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API in the Amazon S3 User Guide.
If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.
bytes or seekable file-like object
Object data.
string
[REQUIRED]
The bucket name to which the PUT action was initiated.
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az2--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.
Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
string
Can be used to specify caching behavior along the request/reply chain. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.
string
Specifies presentational information for the object. For more information, see https://www.rfc-editor.org/rfc/rfc6266#section-4.
string
Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#field.content-encoding.
string
The language the content is in.

string
The base64-encoded 128-bit MD5 digest of the message (without the headers) according to RFC 1864. This header can be used as a message integrity check to verify that the data is the same data that was originally sent. Although it is optional, we recommend using the Content-MD5 mechanism as an end-to-end integrity check. For more information about REST request authentication, see REST Authentication.
string
A standard MIME type describing the format of the contents. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-type.
string
Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding x-amz-checksum-algorithm or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request.
For the x-amz-checksum-algorithm header, replace algorithm with the supported algorithm from the following list:
CRC32
CRC32C
SHA1
SHA256
For more information, see Checking object integrity in the Amazon S3 User Guide.
If the individual checksum value you provide through x-amz-checksum-algorithm doesn't match the checksum algorithm you set through x-amz-sdk-checksum-algorithm, Amazon S3 ignores any provided ChecksumAlgorithm parameter and uses the checksum algorithm that matches the provided value in ``x-amz-checksum-algorithm ``.
string
This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32 checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.
string
This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32C checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.
string
This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 160-bit SHA-1 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.
string
This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 256-bit SHA-256 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

(string) --
(string) --
string
The server-side encryption algorithm that was used when you store this object in Amazon S3 (for example, AES256, aws:kms, aws:kms:dsse).
General purpose buckets - You have four mutually exclusive options to protect data using server-side encryption in Amazon S3, depending on how you choose to manage the encryption keys. Specifically, the encryption key options are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS or DSSE-KMS), and customer-provided keys (SSE-C). Amazon S3 encrypts data with server-side encryption by using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to encrypt data at rest by using server-side encryption with other key options. For more information, see Using Server-Side Encryption in the Amazon S3 User Guide.
Directory buckets - For directory buckets, only the server-side encryption with Amazon S3 managed keys (SSE-S3) ( AES256) value is supported.
string
By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide.
string
If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see Object Key and Metadata in the Amazon S3 User Guide.
In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:
x-amz-website-redirect-location: /anotherPage.html
In the following example, the request header sets the object redirect to another website:
x-amz-website-redirect-location: http://www.example.com/
For more information about website hosting in Amazon S3, see Hosting Websites on Amazon S3 and How to Configure Website Page Redirects in the Amazon S3 User Guide.
string
Specifies the algorithm to use when encrypting the object (for example, AES256).
string
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
string
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.
string
If x-amz-server-side-encryption has a valid value of aws:kms or aws:kms:dsse, this header specifies the ID (Key ID, Key ARN, or Key Alias) of the Key Management Service (KMS) symmetric encryption customer managed key that was used for the object. If you specify x-amz-server-side-encryption:aws:kms or x-amz-server-side-encryption:aws:kms:dsse, but do not provide `` x-amz-server-side-encryption-aws-kms-key-id``, Amazon S3 uses the Amazon Web Services managed key ( aws/s3) to protect the data. If the KMS key does not exist in the same account that's issuing the command, you must use the full ARN and not just the ID.
string
Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value is stored as object metadata and automatically gets passed on to Amazon Web Services KMS for future GetObject or CopyObject operations on this object. This value must be explicitly added during CopyObject operations.
boolean
Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Key Management Service (KMS) keys (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.
Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.
string
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.
string
The tag-set for the object. The tag-set must be encoded as URL Query parameters. (For example, "Key1=Value1")
string
The Object Lock mode that you want to apply to this object.
datetime
The date and time when you want this object's Object Lock to expire. Must be formatted as a timestamp parameter.
string
Specifies whether a legal hold will be applied to this object. For more information about S3 Object Lock, see Object Lock in the Amazon S3 User Guide.
string
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

Response Structure
(dict) --
Expiration (string) --
If the expiration is configured for the object (see PutBucketLifecycleConfiguration) in the Amazon S3 User Guide, the response includes this header. It includes the expiry-date and rule-id key-value pairs that provide information about object expiration. The value of the rule-id is URL-encoded.
ETag (string) --
Entity tag for the uploaded object.
General purpose buckets - To ensure that data is not corrupted traversing the network, for objects where the ETag is the MD5 digest of the object, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.
Directory buckets - The ETag for the object in a directory bucket isn't the MD5 digest of the object.
ChecksumCRC32 (string) --
The base64-encoded, 32-bit CRC32 checksum of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
ChecksumCRC32C (string) --
The base64-encoded, 32-bit CRC32C checksum of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
ChecksumSHA1 (string) --
The base64-encoded, 160-bit SHA-1 digest of the object. This will only be present if it was uploaded with the object. When you use the API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
ChecksumSHA256 (string) --
The base64-encoded, 256-bit SHA-256 digest of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
ServerSideEncryption (string) --
The server-side encryption algorithm used when you store this object in Amazon S3 (for example, AES256, aws:kms, aws:kms:dsse).
VersionId (string) --
Version ID of the object.
If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects. For more information about versioning, see Adding Objects to Versioning-Enabled Buckets in the Amazon S3 User Guide. For information about returning the versioning state of a bucket, see GetBucketVersioning.
SSECustomerAlgorithm (string) --
If server-side encryption with a customer-provided encryption key was requested, the response will include this header to confirm the encryption algorithm that's used.
SSECustomerKeyMD5 (string) --
If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide the round-trip message integrity verification of the customer-provided encryption key.

SSEKMSEncryptionContext (string) --
If present, indicates the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value is stored as object metadata and automatically gets passed on to Amazon Web Services KMS for future GetObject or CopyObject operations on this object.
BucketKeyEnabled (boolean) --
Indicates whether the uploaded object uses an S3 Bucket Key for server-side encryption with Key Management Service (KMS) keys (SSE-KMS).
RequestCharged (string) --
If present, indicates that the requester was successfully charged for the request.
{'RestoreRequest': {'OutputLocation': {'S3': {'StorageClass': {'EXPRESS_ONEZONE'}}}}}
Restores an archived copy of an object back into Amazon S3
This functionality is not supported for Amazon S3 on Outposts.
This action performs the following types of requests:
select - Perform a select query on an archived object
restore an archive - Restore an archived object
For more information about the S3 structure in the request body, see the following:
Managing Access with ACLs in the Amazon S3 User Guide
Protecting Data Using Server-Side Encryption in the Amazon S3 User Guide
Define the SQL expression for the SELECT type of restoration for your query in the request body's SelectParameters structure. You can use expressions like the following examples.
The following expression returns all records from the specified object. SELECT * FROM Object
Assuming that you are not using any headers for data stored in the object, you can specify columns with positional headers. SELECT s._1, s._2 FROM Object s WHERE s._3 > 100
If you have headers and you set the fileHeaderInfo in the CSV structure in the request body to USE, you can specify headers in the query. (If you set the fileHeaderInfo field to IGNORE, the first row is skipped for the query.) You cannot mix ordinal positions with header column names. SELECT s.Id, s.FirstName, s.SSN FROM S3Object s
When making a select request, you can also do the following:
To expedite your queries, specify the Expedited tier. For more information about tiers, see "Restoring Archives," later in this topic.
Specify details about the data serialization format of both the input object that is being queried and the serialization of the CSV-encoded query results.
The following are additional important facts about the select feature:
The output results are new Amazon S3 objects. Unlike archive retrievals, they are stored until explicitly deleted-manually or through a lifecycle configuration.
You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't duplicate requests, so avoid issuing duplicate requests.
Amazon S3 accepts a select request even if the object has already been restored. A select request doesn’t return error response 409.
Permissions
To use this operation, you must have permissions to perform the s3:RestoreObject action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.
Restoring objects
Objects that you archive to the S3 Glacier Flexible Retrieval Flexible Retrieval or S3 Glacier Deep Archive storage class, and S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, are not accessible in real time. For objects in the S3 Glacier Flexible Retrieval Flexible Retrieval or S3 Glacier Deep Archive storage classes, you must first initiate a restore request, and then wait until a temporary copy of the object is available. If you want a permanent copy of the object, create a copy of it in the Amazon S3 Standard storage class in your S3 bucket. To access an archived object, you must restore the object for the duration (number of days) that you specify. For objects in the Archive Access or Deep Archive Access tiers of S3 Intelligent-Tiering, you must first initiate a restore request, and then wait until the object is moved into the Frequent Access tier.
To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.
When restoring an archived object, you can specify one of the following data access tier options in the Tier element of the request body:
Expedited - Expedited retrievals allow you to quickly access your data stored in the S3 Glacier Flexible Retrieval Flexible Retrieval storage class or S3 Intelligent-Tiering Archive tier when occasional urgent requests for restoring archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals is typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.
Standard - Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for retrieval requests that do not specify the retrieval option. Standard retrievals typically finish within 3–5 hours for objects stored in the S3 Glacier Flexible Retrieval Flexible Retrieval storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 12 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Standard retrievals are free for objects stored in S3 Intelligent-Tiering.
Bulk - Bulk retrievals free for objects stored in the S3 Glacier Flexible Retrieval and S3 Intelligent-Tiering storage classes, enabling you to retrieve large amounts, even petabytes, of data at no cost. Bulk retrievals typically finish within 5–12 hours for objects stored in the S3 Glacier Flexible Retrieval Flexible Retrieval storage class or S3 Intelligent-Tiering Archive tier. Bulk retrievals are also the lowest-cost retrieval option when restoring objects from S3 Glacier Deep Archive. They typically finish within 48 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.
For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon S3 User Guide.
You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. For more information, see Upgrading the speed of an in-progress restore in the Amazon S3 User Guide.
To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon S3 User Guide.
After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.
If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon S3 User Guide.
Responses
A successful action returns either the 200 OK or 202 Accepted status code.
If the object is not previously restored, then Amazon S3 returns 202 Accepted in the response.
If the object is previously restored, Amazon S3 returns 200 OK in the response.
Special errors:
Code: RestoreAlreadyInProgress
Cause: Object restore is already in progress. (This error does not apply to SELECT type requests.)
HTTP Status Code: 409 Conflict
SOAP Fault Code Prefix: Client
Code: GlacierExpeditedRetrievalNotAvailable
Cause: expedited retrievals are currently not available. Try again later. (Returned if there is insufficient capacity to process the Expedited request. This error applies only to Expedited retrievals and not to S3 Standard or Bulk retrievals.)
HTTP Status Code: 503
SOAP Fault Code Prefix: N/A

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.
string
Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request. For more information, see Checking object integrity in the Amazon S3 User Guide.
If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.
string
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

Passes transformed objects to a GetObject operation when using Object Lambda access points. For information about Object Lambda access points, see Transforming objects with Object Lambda access points in the Amazon S3 User Guide.
This operation supports metadata that can be returned by GetObject, in addition to RequestRoute, RequestToken, StatusCode, ErrorCode, and ErrorMessage. The GetObject response metadata is supported so that the WriteGetObjectResponse caller, typically an Lambda function, can provide the same metadata when it internally invokes GetObject. When WriteGetObjectResponse is called by a customer-owned Lambda function, the metadata returned to the end user GetObject call might differ from what Amazon S3 would normally return.
You can include any number of metadata headers. When including a metadata header, it should be prefaced with x-amz-meta. For example, x-amz-meta-my-custom-header: MyCustomValue. The primary use case for this is to forward GetObject metadata.
Amazon Web Services provides some prebuilt Lambda functions that you can use with S3 Object Lambda to detect and redact personally identifiable information (PII) and decompress S3 objects. These Lambda functions are available in the Amazon Web Services Serverless Application Repository, and can be selected through the Amazon Web Services Management Console when you create your Object Lambda access point.
Example 1: PII Access Control - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically detects personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.
Example 2: PII Redaction - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically redacts personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.
Example 3: Decompression - The Lambda function S3ObjectLambdaDecompression, is equipped to decompress objects stored in S3 in one of six compressed file formats including bzip2, gzip, snappy, zlib, zstandard and ZIP.
For information on how to view and use these functions, see Using Amazon Web Services built Lambda functions in the Amazon S3 User Guide.

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 32-bit CRC32 checksum of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation. For more information about checksums, see Checking object integrity in the Amazon S3 User Guide.
Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.
