We're starting a preview period for the[protected branches](https://github.com/blog/2051-protected-branches-and-required-status-checks) API. Protecting a branch prevents force-pushes to it as well as deleting it. You can also specify required status checks that are required to merge code into the branch.

To protect a branch, make a`PATCH` request to the URL of the branch:

{:.terminal}

curl "https://api.github.com/v3/repos/github/hubot/branches/master"\

-XPATCH\

-H 'Authorization: token TOKEN'

-H "Accept: application/vnd.github.loki-preview"\

-d "{\"protection\":{\"enabled\":true,\"required_status_checks\":{\"enforcement_level\":\"everyone\",\"contexts\":[\"required-status\"]}}}"\
