title: How to get all posts of a group via facebook graph api
body: <p>I want to grab all the posts from the facebook group with reference to its ID. I tried this: </p>
  
  <pre><code>https://graph.facebook.com/".$group_id."/feed?time_format=U&amp;".$authToken
  </code></pre>
  
  <p>which only gives me certain posts. I want all the posts to be retrieved by a single url if possible if not by pagination url. But pagination url contains paging token as</p>
  
  <pre><code>https://graph.facebook.com/55259308085/feed?limit=500&amp;access_token=ACCESS_TOKEN&amp;until=1298025645&amp;__paging_token=55259308085_10150259582898086
