title: How to Logout of an Application Where I Used OAuth2 To Login With Google?
body: <p>In my application, I implemented Google signout using jsapi.</p>
  
  <p>I used the url <a href="https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=xxxxxx" rel="noreferrer">https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=xxxxxx</a> to connect to Google and then <a href="https://www.googleapis.com/plus/v1/people/xxxxxx" rel="noreferrer">https://www.googleapis.com/plus/v1/people/xxxxxx</a> to get user data from google profile.</p>
  
  <p>Now I need to signout the user from Google while clicking a button from my application. How can I implement this in JavaScript, or at least it must ask the Google login page every time the user signs in.</p>
  
  <p>I have tried <code>approval_prompt=force</code>, but seems not to be working.</p>
