Lists versions for the specified state machine Amazon Resource Name (ARN).
The results are sorted in descending order of the version creation time.
If nextToken is returned, there are more results available. The value of nextToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged. Each pagination token expires after 24 hours. Using an expired pagination token will return an HTTP 400 InvalidToken error.

updateDate (datetime) --
The date and time the state machine alias was updated.
Creates an alias for a state machine that points to one or two versions of the same state machine. You can set your application to call StartExecution with an alias and update the version the alias uses without changing the client's code.
You can also map an alias to split StartExecution requests between two versions of a state machine. To do this, add a second RoutingConfig object in the routingConfiguration parameter. You must also specify the percentage of execution run requests each version should receive in both RoutingConfig objects. Step Functions randomly chooses which version runs a given execution based on the percentage you specify.
To create an alias that points to a single version, specify a single RoutingConfig object with a weight set to 100.
You can create up to 100 aliases for each state machine. You must delete unused aliases using the DeleteStateMachineAlias API action.
CreateStateMachineAlias is an idempotent API. Step Functions bases the idempotency check on the stateMachineArn, description, name, and routingConfiguration parameters. Requests that contain the same values for these parameters return a successful idempotent response without creating a duplicate resource.

Creates a version from the current revision of a state machine. Use versions to create immutable snapshots of your state machine. You can start executions from versions either directly or with an alias. To create an alias, use CreateStateMachineAlias.
You can publish up to 1000 versions for each state machine. You must manually delete unused versions using the DeleteStateMachineVersion API action.
PublishStateMachineVersion is an idempotent API. It doesn't create a duplicate state machine version if it already exists for the current revision. Step Functions bases PublishStateMachineVersion's idempotency check on the stateMachineArn, name, and revisionId parameters. Requests with the same parameters return a successful idempotent response. If you don't specify a revisionId, Step Functions checks for a previously published version of the state machine's current revision.

Creates a state machine. A state machine consists of a collection of states that can do work ( Task states), determine to which states to transition next ( Choice states), stop an execution with an error ( Fail states), and so on. State machines are specified using a JSON-based, structured language. For more information, see Amazon States Language in the Step Functions User Guide.
If you set the publish parameter of this API action to true, it publishes version 1 as the first revision of the state machine.

Returns the history of the specified execution as a list of events. By default, the results are returned in ascending order of the timeStamp of the events. Use the reverseOrder parameter to get the latest events first.
If nextToken is returned, there are more results available. The value of nextToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged. Each pagination token expires after 24 hours. Using an expired pagination token will return an HTTP 400 InvalidToken error.
This API action is not supported by EXPRESS state machines.

{'publish': 'boolean', 'versionDescription': 'string'}
Response {'revisionId': 'string', 'stateMachineVersionArn': 'string'}
Updates an existing state machine by modifying its definition, roleArn, or loggingConfiguration. Running executions will continue to use the previous definition and roleArn. You must include at least one of definition or roleArn or you will receive a MissingRequiredParameter error.
A qualified state machine ARN refers to a Distributed Map state defined within a state machine. For example, the qualified state machine ARN arn:partition:states:region:account-id:stateMachine:stateMachineName/mapStateLabel refers to a Distributed Map state with a label mapStateLabel in the state machine named stateMachineName.
A qualified state machine ARN can either refer to a Distributed Map state defined within a state machine, a version ARN, or an alias ARN.
The following are some examples of qualified and unqualified state machine ARNs:
The following qualified state machine ARN refers to a Distributed Map state with a label mapStateLabel in a state machine named myStateMachine. arn:partition:states:region:account-id:stateMachine:myStateMachine/mapStateLabel
The following qualified state machine ARN refers to an alias named PROD. arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine:PROD>
The following unqualified state machine ARN refers to a state machine named myStateMachine. arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine>
After you update your state machine, you can set the publish parameter to true in the same action to publish a new version. This way, you can opt-in to strict versioning of your state machine.
