Want to duplicate the jira issue key -> full URL functionality for other keys

[Evan hamrick]

Our helpdesk system pulls up tickets with a url in the form of helpdesk/page.asp?id=00000, so I'd like Jira to render text in the form of {prefix}{id} (e.g., HD#00000) as a clickable link to the appropriately formatted helpdesk url

Edit-

https://community.atlassian.com/t5/Jira-questions/How-to-transform-a-custom-text-field-in-a-URL-it-is-displayed-by/qaq-p/340236 seems related, but I'd prefer to not have to have a separate field for the ticket ID

Best you can do is create a url field and post the full urls into there.

If you have an automation or scripting tool, you can go a step further and possibly auto-generate it from a user entering the plain number.

Thanks for the quick answer Nic; by scripting or automation you mean something to watch for updates via the API and parse things out appropriately?

Yes, correct.
