Anyone with admin permissions to a repository can configure autolink references to link issues, pull requests, commit messages, and release descriptions to external third-party services.
If you use Zendesk to track user-reported tickets, for example, you can reference a ticket number in the pull request you open to fix the issue.
{% data reusables.repositories.navigate-to-repo %}
