Using Bitbucket Server 8.3.3, I can use the REST API to fetch information about pull requests for a repository.
Example: /rest/api/latest/projects/<PROJ>/repos/<REPO>/pull-requests/<ID_NO>
The response provides the author info, the state of the request, approvers etc.
In the event that a pull request was merged remotely, this information shows in the UI - is there an equivalent information available via any REST API? Without it, it appears as if the request was merged without approval
