How to set up integration in order to retrieve custom fields from Jira Instance into ServiceNow Instance via GET Issue by IDIssue In KB0815305 we created a custom field in Jira and you would like to have it retrieved by ServiceNow while running a "Get Issue by ID" Action.You will notice that following the regular "Get Issue by ID" process, your custom field exemplified in KB0815305will return your fields as following: "customfield_10057":"testingtesting" , instead of "Testingcustomfield":"testingtesting". We see therefore that in response, Jira sends its own label instead of the one of created by ServiceNow. This can be sometimes confusing and inconsistent behaviour.ReleaseLondon onwardsResolutionIn order to workaround this behaviour, so that the field is mapped correctly, follow the below steps: In the configuration screen click on "Open Action in Action Designer" Then expand "Get Issue by ID" action and in the Query Parameters ad the following: Name=expandValue=names Fill in the project name and Run the test. Now you should see in the payload the below: customfield_10057":"Testingcustomfield" additional to "customfield_10057":"testingtesting" This will help you map the fields in the response, and match the value with the label. Important note: In order to be able to modify this action, you would need to create a copy of the action (as admin) and thereafter implement the above workaround on the newly copied action.
