| **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`. |

is a number used in the target project of the custom integration.
`<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.
