# DeleteStateMachine
<a name="API_DeleteStateMachine"></a>

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` 
**Note**  
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](https://docs.aws.amazon.com/step-functions/latest/dg/concepts-state-machine-version.html) and [aliases](https://docs.aws.amazon.com/step-functions/latest/dg/concepts-state-machine-alias.html) associated with a state machine.

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