<p>Returns information about the specified workflow execution including its type and some statistics.</p> <note> <p>This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.</p> </note> <p> <b>Access Control</b> </p> <p>You can use IAM policies to control this action's access to Amazon SWF resources as follows:</p> <ul> <li> <p>Use a <code>Resource</code> element with the domain name to limit the action to only specified domains.</p> </li> <li> <p>Use an <code>Action</code> element to allow or deny permission to call this action.</p> </li> <li> <p>You cannot use an IAM policy to constrain this action's parameters.</p> </li> </ul> <p>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 <code>cause</code> parameter is set to <code>OPERATION_NOT_PERMITTED</code>. For details and example IAM policies, see <a href="https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html">Using IAM to Manage Access to Amazon SWF Workflows</a> in the <i>Amazon SWF Developer Guide</i>.</p>
