title: Is it possible to use google OAuth to pull user-specific data from a non-google website that uses "Sign in with Google"?
body: <p>I would like to be able to pull information from a website periodically for my users. This website requires google authentication (Sign in with Google) and thus requires a cookie to be sent along with all HTTP requests.</p>
  <p>If I implement google OAuth in my own app, I will be given an access token and a refresh token. But, from my knowledge of Google's protocols, I will be unable to use these to access non-google APIs.</p>
  <p>So, essentially, my question is this:
  If my user logs in to MY app with google, am I able to authenticate my server to fetch data on their behalf?</p>
  <p>Other information:
  This is a web app</p>
