title: Catching json data from hubspot webhook
body: <p>For the life of me I can't figure out what I am missing. I am using HubSpot and have a workflow setup to use a web hook that posts to a script that I have. When I set the url to capture the webhook data onto requestb.in it passed the data and I can see the raw json data. But when I try to capture it with my own code and write it to a text file, I get absolutely nothing.</p>
  
  <p>I have tried things like:</p>
  
  <pre><code>$myFile = "testFile.txt";
  $fh = fopen($myFile, 'w') or die("can't open file");
  
  fwrite($fh, $_POST);
  fwrite($fh, $_GET);
  fwrite($fh, $_REQUEST);
  fwrite($fh, $_POST['message']);
  fwrite($fh, $_GET['message']);
  
  fclose($fh);
  </code></pre>
  
  <p>And no matter what I do - I can't capture the data being posted from the webhook.</p>
  
  <p>So here's my question. In a normal procedure, when json data is posted from an api,
  am I correct in asking that the "variable" of the json data is usually "message" 
  (For example: $_POST['message'])?</p>
  
  <p>And I would kindly ask a pointer as to what I am missing or doing wrong that won't allow me to capture this data. I am really beginning to think it's HubSpot and not me, but I need to confirm that first.</p>
  
  <p>Thanks</p>
