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

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginDescribeStateMachine and EndDescribeStateMachine.
