I want to have status reported to my Github Enterprise repository. How can I do this?

Bitrise Checks works only on Github, not on Github Enterprise. For Github Enterprise, you can use the Github Status Step.

The Step uses https://developer.github.com/v3/repos/statuses/ endpoints.

When a status is reported for a PR, it will show up first on Github surface in the Repository settings tab, under Branches > Branch protection rules.

Create a new rule. This should bring up the rule edit view. Select the report in the bottom to make it show up on the PR view.

Statuses are always set for a commit hash. Each time a PR is created, it will belong to the commit hash itself. Each commit will have its own commit hash.
