| `issues_url` | The URL to the issue in the issue tracker project that is linked to this GitLab project. Note that the `issues_url` requires `:id` in the URL. This ID is used by GitLab as a placeholder to replace the issue number. For example, `https://customissuetracker.com/project-name/:id`. |
| `new_issue_url` | Currently unused. Will be changed in a future release. |
Once you have configured and enabled Custom Issue Tracker Service you'll see a link on the GitLab project pages that takes you to that custom issue tracker.
- Issues are referenced with `ANYTHING-<ID>`, where `ANYTHING` can be any string and `<ID>` is a number used in the target project of the custom integration (example `PROJECT-143`).
-`ANYTHING` is a placeholder to differentiate against GitLab issues, which are referenced with `#<ID>`. You can use a project name or project key to replace it for example.
