https://community.appian.com/discussions/f/process/11754/reagarding-smart-serviceHi, I have a question, While using smart service HTTPQuery() to communicate with external doc management if suppose the corresponding URL doesn&#39;t respond then how do we overcome that issue. Is it possible in Appian or not? Thanks In Advance, ASen-USTelligent Community 12https://community.appian.com/thread/51946?ContentTypeID=1Wed, 24 Jan 2018 07:58:13 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:af6c3c76-ace9-4da9-ba13-348e8d330806aloks0189Hi <a href="/members/aswinis">Aswini </a> as per my understanding,<br /> <br /> 1. HTTP Query Smart Service is not meant to deal with document related operations, but yes it can query the doc url, other informations and post the data to external systems.<br /> <br /> 2. You should capture the output of this smart service, which will indicate isErrorOccured as true if the url is broken. I believe this smart service has proper exception handling to avoid node execution failure<br /> <br /> 3. Apart from that, you can set a timer on this smart Service, considering as timeout period from your end, and flow this timer through a script task, set errorOccured to true() and hence you will have the track of this service invocation whether it was successful or failed.<br /> <br /> Hope this will help you.<div style="clear:both;"></div>https://community.appian.com/thread/51924?ContentTypeID=1Tue, 23 Jan 2018 15:53:52 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:54ee5853-f444-470c-bb65-646124015e67Colton Beck<p>Have you checked the application server logs for more information on the failure?</p> <p>Also keep in mind that the <a href="https://docs.appian.com/suite/help/17.1/fnc_connector_http_a_httpquery.html">httpQuery()</a> function is deprecated and replaced with <a href="https://docs.appian.com/suite/help/17.4/Integration_Object.html">Integration Objects</a></p><div style="clear:both;"></div>
