<p>Used by deciders to tell the service that the <a>DecisionTask</a> identified by the <code>taskToken</code> has successfully completed. The <code>decisions</code> argument specifies the list of decisions made while processing the task.</p> <p>A <code>DecisionTaskCompleted</code> event is added to the workflow history. The <code>executionContext</code> specified is attached to the event in the workflow execution history.</p> <p> <b>Access Control</b> </p> <p>If an IAM policy grants permission to use <code>RespondDecisionTaskCompleted</code>, it can express permissions for the list of decisions in the <code>decisions</code> parameter. Each of the decisions has one or more parameters, much like a regular API call. To allow for policies to be as readable as possible, you can express permissions on decisions as if they were actual API calls, including applying conditions to some parameters.
