title: LinkedIn Access Token to authenticate users and use JSAPI Send a message
body: <p>I am working on the PHP application, that captures "Access Token", when user click on register with Linkedin, I use that access token to get all the related information from the user's Linkedin profile.</p>
  
  <p>I now want to include LinkedIn Send a message feature <a href="http://developer.linkedin.com/documents/sample-code-sending-message" rel="nofollow">http://developer.linkedin.com/documents/sample-code-sending-message</a>. </p>
  
  <p>Is there any way I can use the Send a message feature with authentication process using user's <strong>access token</strong> without showing user to login with linkedIn again to send a message?</p>
