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.
  • tagFilter.tag : String constraint. The key is swf:tagFilter.tag .
  • typeFilter.name : String constraint. The key is swf:typeFilter.name .
  • typeFilter.version : String constraint. The key is swf:typeFilter.version .

If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing OperationNotPermitted . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.
