SFN / Client / delete_state_machine



Deletes a state machine. This is an asynchronous operation. It sets the state machine’s status to DELETING and begins the deletion process. A state machine is deleted only when all its executions are completed. On the next state transition, the state machine’s executions are terminated.

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 unqualified state machine ARN refers to a state machine named myStateMachine. arn:partition:states:region:account-id:stateMachine:myStateMachine

This API action also deletes all versions and aliases associated with a state machine.


For EXPRESS state machines, the deletion happens eventually (usually in less than a minute). Running executions may emit logs after DeleteStateMachine API is called.
