2024/11/22 - Amazon Simple Storage Service - 4 updated api methods
Changes Add support for conditional deletes for the S3 DeleteObject and DeleteObjects APIs. Add support for write offset bytes option used to append to objects with the S3 PutObject API.
{'IfMatchInitiatedTime': 'timestamp'}
This operation aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.
To verify that all parts have been removed and prevent getting charged for the part storage, you should call the ListParts API operation and ensure that the parts list is empty.
General purpose bucket permissions - For information about permissions required to use the multipart upload, 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.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.
The following operations are related to AbortMultipartUpload:
See also: AWS API Documentation
Request Syntax
client.abort_multipart_upload( Bucket='string', Key='string', UploadId='string', RequestPayer='requester', ExpectedBucketOwner='string', IfMatchInitiatedTime=datetime(2015, 1, 1) )
string
[REQUIRED]
The bucket name to which the upload was taking place.
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-az1--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
[REQUIRED]
Key of the object for which the multipart upload was initiated.
string
[REQUIRED]
Upload ID that identifies the multipart upload.
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 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).
datetime
If present, this header aborts an in progress multipart upload only if it was initiated on the provided timestamp. If the initiated timestamp of the multipart upload does not match the provided value, the operation returns a 412 Precondition Failed error. If the initiated timestamp matches or if the multipart upload doesn’t exist, the operation returns a 204 Success (No Content) response.

{'IfMatch': 'string', 'IfMatchLastModifiedTime': 'timestamp', 'IfMatchSize': 'long'}
Removes an object from a bucket. The behavior depends on the bucket's versioning state. For more information, see Best practices to consider before deleting an object.
To remove a specific version, you must use the versionId query parameter. Using this query parameter permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header x-amz-delete-marker to true. If the object you want to delete is in a bucket where the bucket versioning configuration is MFA delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS. For more information about MFA delete and to see example requests, see Using MFA delete and Sample request in the Amazon S3 User Guide.
General purpose bucket permissions - The following permissions are required in your policies when your DeleteObjects request includes specific headers.
s3:DeleteObject - To delete an object from a bucket, you must always have the s3:DeleteObject permission.
s3:DeleteObjectVersion - To delete a specific version of an object from a versioning-enabled bucket, you must have the s3:DeleteObjectVersion permission.
If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject, s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration permissions.
Directory buckets 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.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

{'Delete': {'Objects': {'ETag': 'string', 'LastModifiedTime': 'timestamp', 'Size': 'long'}}}
This operation enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this operation provides a suitable alternative to sending individual delete requests, reducing per-request overhead.
The request can contain a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete operation and returns the result of that delete, success or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.
The operation supports two modes for the response: verbose and quiet. By default, the operation uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete operation encountered an error. For a successful deletion in a quiet mode, the operation does not return any information about the delete in the response body.
When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete in the Amazon S3 User Guide.
General purpose bucket permissions - The following permissions are required in your policies when your DeleteObjects request includes specific headers.
s3:DeleteObject - To delete an object from a bucket, you must always specify the s3:DeleteObject permission.
s3:DeleteObjectVersion - To delete a specific version of an object from a versioning-enabled bucket, you must specify the s3:DeleteObjectVersion permission.
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.
Content-MD5 request header
General purpose bucket - The Content-MD5 request header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.
Directory bucket - The Content-MD5 request header or a additional checksum request header (including x-amz-checksum-crc32, x-amz-checksum-crc32c, x-amz-checksum-sha1, or x-amz-checksum-sha256) is required for all Multi-Object Delete requests.
HTTP Host header syntax

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-az1--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 performing the DeleteObjects operation on an MFA delete enabled bucket, which attempts to delete the specified versioned objects, you must include an MFA token. If you don't provide an MFA token, the entire request will fail, even if there are non-versioned objects that you are trying to delete. If you provide an invalid token, whether there are versioned object keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete in the Amazon S3 User Guide.
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.
boolean
Specifies whether you want to delete this object even if it has a Governance-type Object Lock in place. To use this header, you must have the s3:BypassGovernanceRetention permission.
string

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 ``.
If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

Message (string) --
The error message contains a generic description of the error condition in English. It is intended for a human audience. Simple programs display the message directly to the end user if they encounter an error condition they don't know how or don't care to handle. Sophisticated programs with more exhaustive error handling and proper internationalization are more likely to ignore the error message.
{'WriteOffsetBytes': 'long'}Response
{'Size': 'long'}
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. If the object is encrypted with SSE-KMS, you must also have the kms:GenerateDataKey and kms:Decrypt permissions in IAM identity-based policies and KMS key policies for the KMS key.
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-az1--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.
integer
Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-length.
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 ``.
For directory buckets, when you use Amazon Web Services SDKs, CRC32 is the default checksum algorithm that's used for performance.
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 CRC-32 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 CRC-32C 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.
datetime
The date and time at which the object is no longer cacheable. For more information, see https://www.rfc-editor.org/rfc/rfc7234#section-5.3.
string
Uploads the object only if the object key name does not already exist in the bucket specified. Otherwise, Amazon S3 returns a 412 Precondition Failed error.
If a conflicting operation occurs during the upload S3 returns a 409 ConditionalRequestConflict response. On a 409 failure you should retry the upload.
Expects the '*' (asterisk) character.
For more information about conditional requests, see RFC 7232, or Conditional requests in the Amazon S3 User Guide.
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]
Object key for which the PUT action was initiated.
integer
Specifies the offset for appending data to existing objects in bytes. The offset must be equal to the size of the existing object being appended to. If no object exists, setting this header to 0 will create a new object.
dict
A map of metadata to store with the object in S3.
(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, there are only two supported options for server-side encryption: server-side encryption with Amazon S3 managed keys (SSE-S3) ( AES256) and server-side encryption with KMS keys (SSE-KMS) ( aws:kms). We recommend that the bucket's default encryption uses the desired encryption configuration and you don't override the bucket default encryption in your CreateSession requests or PUT object requests. Then, new objects are automatically encrypted with the desired encryption settings. For more information, see Protecting data with server-side encryption in the Amazon S3 User Guide. For more information about the encryption overriding behaviors in directory buckets, see Specifying server-side encryption with KMS for new object uploads. In the Zonal endpoint API calls (except CopyObject and UploadPartCopy) using the REST API, the encryption request headers must match the encryption settings that are specified in the CreateSession request. You can't override the values of the encryption settings ( x-amz-server-side-encryption, x-amz-server-side-encryption-aws-kms-key-id, x-amz-server-side-encryption-context, and x-amz-server-side-encryption-bucket-key-enabled) that are specified in the CreateSession request. You don't need to explicitly specify these encryption settings values in Zonal endpoint API calls, and Amazon S3 will use the encryption settings values from the CreateSession request to protect new objects in the directory bucket.
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
Specifies the KMS key ID (Key ID, Key ARN, or Key Alias) to use for object encryption. If the KMS key doesn't exist in the same account that's issuing the command, you must use the full Key ARN not the Key ID.
General purpose buckets - If you specify x-amz-server-side-encryption with aws:kms or aws:kms:dsse, this header specifies the ID (Key ID, Key ARN, or Key Alias) of the KMS key to use. 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.
Directory buckets - If you specify x-amz-server-side-encryption with aws:kms, the x-amz-server-side-encryption-aws-kms-key-id header is implicitly assigned the ID of the KMS symmetric encryption customer managed key that's configured for your directory bucket's default encryption setting. If you want to specify the x-amz-server-side-encryption-aws-kms-key-id header explicitly, you can only specify it with the ID (Key ID or Key ARN) of the KMS customer managed key that's configured for your directory bucket's default encryption setting. Otherwise, you get an HTTP 400 Bad Request error. Only use the key ID or key ARN. The key alias format of the KMS key isn't supported. Your SSE-KMS configuration can only support 1 customer managed key per directory bucket for the lifetime of the bucket. The Amazon Web Services managed key ( aws/s3) isn't supported.
string
Specifies the Amazon Web Services KMS Encryption Context as an additional encryption context to use for object encryption. The value of this header is a Base64-encoded string of a UTF-8 encoded JSON, which contains the encryption context as key-value pairs. This value is stored as object metadata and automatically gets passed on to Amazon Web Services KMS for future GetObject operations on this object.
General purpose buckets - This value must be explicitly added during CopyObject operations if you want an additional encryption context for your object. For more information, see Encryption context in the Amazon S3 User Guide.
Directory buckets - You can optionally provide an explicit encryption context value. The value must match the default encryption context - the bucket Amazon Resource Name (ARN). An additional encryption context value is not supported.
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).
General purpose buckets - Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS. Also, specifying this header with a PUT action doesn't affect bucket-level settings for S3 Bucket Key.
Directory buckets - S3 Bucket Keys are always enabled for GET and PUT operations in a directory bucket and can’t be disabled. S3 Bucket Keys aren't supported, when you copy SSE-KMS encrypted objects from general purpose buckets to directory buckets, from directory buckets to general purpose buckets, or between directory buckets, through CopyObject, UploadPartCopy, the Copy operation in Batch Operations, or the import jobs. In this case, Amazon S3 makes a call to KMS every time a copy request is made for a KMS-encrypted object.
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) --

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 CRC-32C 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.
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.
SSEKMSKeyId (string) --

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 string of a UTF-8 encoded JSON, which contains the encryption context as key-value pairs. This value is stored as object metadata and automatically gets passed on to Amazon Web Services KMS for future GetObject 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).
Size (integer) --
The size of the object in bytes. This will only be present if you append to an object.
RequestCharged (string) --
If present, indicates that the requester was successfully charged for the request.
