This question is in reference to Atlassian Documentation: Configuring a custom field
How do I determine the custom field id for Jira integration? I think it's numeric...
If you go to Administration > Custom Fields and click on "Edit" (or hover over the Edit operation), you can see the custom field id at the end of the url.
