title: Delete facebook post with Graph API - trouble getting this to work
body: <p>I'm using the following to post a message on my Facebook page:</p>
  
  <pre><code>$attachment =  array(
      'access_token' =&gt; $access_token,
      'message' =&gt; 'This is a test Message 4:',   
      'name' =&gt; "This is a test Name 4",
      'link' =&gt; "http://slashdot.org/",
      'description' =&gt; "This is a test Description 4"
  );
  
  $ret_code=$facebook-&gt;api('/me/feed', 'POST', $attachment);
  </code></pre>
  
  <p>This works great.  </p>
  
  <p>How do I delete the same post using the facebook GRAPH api? I read the docs and it says to issue a POST like: </p>
  
  <p><a href="https://graph.facebook.com/COMMENT_ID?method=delete" rel="noreferrer">https://graph.facebook.com/COMMENT_ID?method=delete</a></p>
  
  <p>To test I set this up in a simple form with submit button, POSTing the data to <a href="https://graph.facebook.com/COMMENT_ID?method=delete" rel="noreferrer">https://graph.facebook.com/COMMENT_ID?method=delete</a> (substituting COMMENT_ID fro the 11111111111_111111111111 id returned from the original publish call.   This returns "This API call requires a valid app_id".</p>
  
  <p>What is the correct way to issue a DELETE command?  </p>
