Github webhooks - pre-push hooks

Question

My requirement is that whenever developers are pushing to github, then before the push a CI build should trigger on Jenkins server. If that build fails, then push to github

Answer 1

After some research, I've found that it is possible to trigger jenkins build using github's webhooks, but it's not possible to reject the github push request if the jenkins' build fails. So, basically, we cannot control the github's push, atleast not in free github account.
