Topic is defined when you create a new probe for discovery or javascript etc. Here is the documentation:https://docs.servicenow.com/csh?topicname=t_CustomProbeTextFile.html&version=latesthttps://docs.servicenow.com/csh?topicname=r_Probes.html&version=latest How to create Custom powershell probe with custom topic:https://docs.servicenow.com/csh?topicname=t_CreateACustomPowershellProbe.html&version=latest setEccTopic() method is used in the scripts or BR or Scripted REST/SOAP services to set the topic name based on which mid server will take the appropriate action on a specific transaction defined in these scripts. Example: var state = new sn_ws.RESTMessageV2(); state.setEccTopic("<topic name mapped to a probe>"); Sample code : var endPoint = gs.getProperty('<property that defines end point>');var customAPI = new sn_ws.RESTMessageV2('<your rest message and function>');customAPI.setStringParameter('url', endPoint);customAPI.setRequestHeader("transactionId", tranID);customAPI.setEccTopic("<topic name mapped to a probe>" );var responsecustomAPI = customAPI.executeAsync(); //executeAsync
