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.
You cannot use an IAM policy to constrain this action's parameters.
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.
