title: Convert `oauth_token` to `access_token` in LinkedIn OAuth 2 API
body: <p>How can a user convert a <code>oauth_token</code> (a short lived token) that is generated from the JavaScript SDK to a <code>access_token</code> (long lived token). I do not see any such information in the documentation, so not sure how to do that. I can see that I can use this <code>oauth_token</code> for accessing LinkedIn services, but to use it for a longer period , I would like to convert that to a long lived <code>access_token</code>.</p>
  
  <p>I have seen the REST API's flow, but that does not seem to be helpful to what I was looking for.</p>
  
  <p>Any help would be grateful. </p>
