Question from my comment here: How to check mergeability of a branches using the github api
Is it possible to check the mergeability of two branches using the github API without making a PR? I dont want to trigger anything by creating a PR, even if I immediately delete the PR afterwards.
You can try and use the GitHub API compare commits (which can be used for branches), as I illustrated here.
That will give you a status:
"status": "behind",
"ahead_by": 1,
"behind_by": 2,
If you see only ahead: the branch will be easily mergeable (fast-forward).
If you see both ahead and behind... there might be conflict, but it is harder to be sure.
