title: Token validation from backend for Google+ Login on Android Application
body: <p>I am following this <a href="https://developers.google.com/identity/sign-in/web/backend-auth" rel="nofollow">link</a> to validate the token. It is mentioned in the link that for more than 100 requests we should follow below approach.</p>
  
  <p>Using one of the Google API Client Libraries is the recommended way to validate Google ID tokens in a production environment.</p>
  
  <p>The link provides code sample in Java. However I am trying to implement the same in Node.js. But did not find any help on this.</p>
  
  <p>Can anybody help me in this?</p>
