title: 3rd party payment provider Google Analytics
body: <p>A checkout flow goes like this:</p>
  <ul>
  <li>user picks a product and goes in checkout flow on mydomain.com</li>
  <li>user pays on otherdomain.com</li>
  <li>user is redirected to a thank you page on mydomain.com</li>
  </ul>
  <p>The problem:
  All source/channel for the conversions were marked referral from otherdomain.com</p>
  <p>What I tried:
  Adding otherdomain.com to exlused domains in Universal Analytics. Referral is gone, but now the source shows&quot;direct/none&quot;. No new session is started each time, but I still can't connect the dots.</p>
  <p>I'm sure this issue pops up a lot, so I'm curious how you solve it.</p>
  <p>Bonus question: a few guides suggested we should exclude mydomain.com too. Why is that?</p>
