title: Facebook payments, credit api , Test users can't get the details of test transaction order_id
body: <p>I am using Facebook Credits.</p>
  
  <p>I have set my user id as test user in app dashboard payments section.</p>
  
  <p>Evey thing works fine, the transaction completed successfully, I get the order_id , then while fetching the details of that order_id to check whether it exists or not, the facebook Api gives the error</p>
  
  <pre><code>Fatal error: Uncaught GraphMethodException: Unsupported get request. thrown in 
  </code></pre>
  
  <p>and testing by file_get_contents gives the following error</p>
  
  <pre><code>failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request 
  </code></pre>
  
  <p>Using cUrl for checking its details also didn't work.</p>
  
  <p>and the big point is that when i copy the link ( which is to be executed either by Facebook graph api, file_get_contents, and by cUrl ) and paste it in url, It works very fine.</p>
  
  <p>I am so much worried, what is the problem with Facebook api, file_get_contents.</p>
  
  <p>Kindly help me in this regard.
  Thanks in advance</p>
