title: How to use github api v3 to revert a pull request, or revert a commit? (NOT from github UI)
body: <p>The problem has been described clear on title</p>
  
  <p>I have read the document at : <a href="https://developer.github.com/v3/pulls/" rel="noreferrer">https://developer.github.com/v3/pulls/</a></p>
  
  <p>NO code needed</p>
  
  <p>I just want to know is that possible?  If yes, which API I should look into?  Or impossible for now, I will look for other solution path.</p>
