SWF / Client / undeprecate_activity_type



Undeprecates a previously deprecated activity type. After an activity type has been undeprecated, you can create new tasks of that activity type.


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

Access Control

You can use IAM policies to control this action’s access to Amazon SWF resources as follows:

  • Use a Resource element with the domain name to limit the action to only specified domains.

  • Use an Action element to allow or deny permission to call this action.

  • Constrain the following parameters by using a Condition element with the appropriate keys.

    • activityType.name: String constraint. The key is swf:activityType.name.

    • activityType.version: String constraint. The key is swf:activityType.version.

If the caller doesn’t have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute’s cause parameter is set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.
