body: <p>Hi all could you just tell what is the difference between Twitter Authenticate and Authorize </p>
  
  <pre><code>$twitterConnect = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
  $twitterToken = $twitterConnect-&gt;getRequestToken();
  
  $redirect_url = $twitterConnect-&gt;getAuthorizeURL($twitterToken, true); // authenticate 
  $redirect_url = $twitterConnect-&gt;getAuthorizeURL($twitterToken, false); //authorize
  </code></pre>
