<p>Deletes a grant. Typically, you retire a grant when you no longer need its permissions. To identify the grant to retire, use a <a href="https://docs.aws.amazon.com/kms/latest/developerguide/grants.html#grant_token">grant token</a>, or both the grant ID and a key identifier (key ID or key ARN) of the KMS key. The <a>CreateGrant</a> operation returns both values.</p> <p>This operation can be called by the <i>retiring principal</i> for a grant, by the <i>grantee principal</i> if the grant allows the <code>RetireGrant</code> operation, and by the Amazon Web Services account in which the grant is created. It can also be called by principals to whom permission for retiring a grant is delegated.
