GitHub API - Equivalent of GitLab's Protected branch API

Question

There is a feature named Protected branches API on GitLab API. Basically, you can restrict all the push and merge access by setting their levels to 0.

I have checked Branches section on GitHub REST API document but I couldn't find the equivalent API. How can I restrict merge and push to a branch on GitHub? Also, I want to remove this restriction after some operations.

protect master branch (do not allow any push, merge etc.)
do something
unprotect master branch

Answer 1

Going to the github api documentation, I see they have added protections. This seems pretty clear how to add proctections using API now.
