title: Google Analytics Measurement Protocol ignores products
body: <p>I am using the Google Measurement protocol to send successful transactions from delayed payments to the analytics server. Everything works fine except for the product information that just wont show up in Google Analytics. </p>
  
  <p>I have already checked if Advanced e-commerce is enabled in Analytics and tried several basic examples from the site, but nothing sticks. I used the following string (UA-ID is fake for obvious reasons.): </p>
  
  <blockquote>
    <p>v=1&amp;t=transaction&amp;tid=UA-12345678-1&amp;cid=b499f0c3-792c-4e4f-a717-d2a85ac55504&amp;ti=250303&amp;tr=105&amp;tt=10&amp;ts=5&amp;cu=EUR&amp;ds=web&amp;pr1id=testsku&amp;pr1nm=test%20product%20description&amp;pr1ca=hardware&amp;pr1pr=100&amp;pr1qt=1</p>

  <p>The measurement protocol hit builder says its a valid request, and the transaction also shows up in GA, but the actual products are missing:</p>

  I have already contacted Google Analytics support, but they had no idea :).</p>
