Delete a branch

DELETE/repos/{owner}/{name}/branches/{branch}

Needs the Write role or higher, and the repository’s rules for deleting the branch hold; the default branch is never deleted. Give head, the commit you saw it at, to leave it alone if someone has pushed since. Returns the branch as it was: its commits stay in the repository, so create_branch with that commit as from restores it. Open pull requests from it can no longer be updated or merged until it is back. Give a branch with slashes URL-encoded in the path, e.g. feature%2Flogin.

The branch as it was. Its commits stay in the repository: POST /repos/{owner}/{name}/branches with this hash as from restores it. Add ?head=<sha> to leave it alone (409) if it has moved from the commit you saw. Refused with 403 for the default branch, without the Write role, or when the repository’s rules refuse it, and 404 when there is no such branch. Send a branch name with slashes URL-encoded, as one path segment. See Branches.
