      operationId: CreateActivity
      description: <p>Creates an activity. An activity is a task that you write in any programming language and host on any machine that has access to Step Functions. Activities must poll Step Functions using the <code>GetActivityTask</code> API action and respond using <code>SendTask*</code> API actions. This function lets Step Functions know the existence of your activity and returns an identifier for use in a state machine and when polling from the activity.</p> <note> <p>This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.</p> </note> <note> <p> <code>CreateActivity</code> is an idempotent API. Subsequent requests won’t create a duplicate resource if it was already created. <code>CreateActivity</code>'s idempotency check is based on the activity <code>name</code>. If a following request has different <code>tags</code> values, Step Functions will ignore these differences and treat it as an idempotent request of the previous. In this case, <code>tags</code> will not be updated, even if they are different.</p> </note>
