title: Send order refund to google analytics
body: <p>I get all the information about the order and sent it to google analytics (<a href="http://www.google-analytics.com/collect" rel="nofollow">http://www.google-analytics.com/collect</a>) through PHP curl.
  My data:</p>
  
  <pre><code>Array
  (
      [t] =&gt; transaction
      [ti] =&gt; 5555
      [tr] =&gt; 200.00
      [ts] =&gt; 10.00
      [tt] =&gt; 5.00
      [cu] =&gt; EUR
      [v] =&gt; 1
      [dh] =&gt; test.com
      [dl] =&gt; http://test.com/
      [dr] =&gt; http://test.com/index.php?
      [tid] =&gt; UA-XXXX-1
      [cid] =&gt; 452396293
  )
  </code></pre>
  
  <p>Everything works fine, I can see the orders in Google Analytics system.</p>
  
  <p>How to cancel an order now? I need send refund status to GA, but how?</p>
  
  <p>By google doc need add "pa=detail".</p>
  
  <p>But what I still need to send there? How looks like "Hit type" (t)?
  Maybe somebody can show refund example.</p>
