Is that correct?</p> <p>If yes, oAuth tokens always have a pretty short expiration time and the other system needs to get a new one calling the endpoint /suite/authorization/oauth/token to get a new one.</p> <p><a href="https://docs.appian.com/suite/help/22.2/Appian_Administration_Console.html#oauth-20-clients">docs.appian.com/.../Appian_Administration_Console.html</a></p><div style="clear:both;"></div>
