title: Refresh LinkedIn Access Token using Scribe
body: <p>I am using Scribe to access the LinkedIn API. I am saving the Access Token along with the Access Token Secret in the database and use them every time I call the API.</p>
  
  <p>The Access Token is supposed to expire 60 days after it has been generated.</p>
  
  <p>I would like to automatically refresh the access token before it expires. I couldn't find a way to do it programatically without the user intervention.</p>
