Redmine integration is only available in RhodeCode Enterprise.
In order to make issue numbers clickable in commit messages, see the section Issue Tracker Integration. Redmine integration is specifically for altering Redmine issues.
Redmine integration allows you to reference and change issue statuses in
Redmine directly from commit messages, using commit message patterns such as
fixes #235 in order to change the status of issue 235 to eg. “Resolved”.
To set a Redmine integration up, it is first necessary to obtain a Redmine API key. This can be found under My Account in the Redmine application. You may have to enable API Access in Redmine settings if it is not already available.
Once you have the API key, create a Redmine integration as outlined in Creating an Integration.
