Provides information about a state machine's definition, its IAM role Amazon Resource Name (ARN), and configuration.

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
If you provide a qualified state machine ARN that refers to a Distributed Map state, the request fails with ValidationException.
The following qualified state machine ARN refers to an alias named PROD.
```
arn::states:::stateMachine:
```
If you provide a qualified state machine ARN that refers to a version ARN or an alias ARN, the request starts execution for that version or alias.
The following unqualified state machine ARN refers to a state machine named myStateMachine.
```
arn::states:::stateMachine:
```

This API action returns the details for a state machine version if the stateMachineArn you specify is a state machine version ARN.

This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.
