title: iOS IAP - Do I need my own server to check for refunds?
body: <p>As a new iOS developer, I was surprised to see that over all the years it has been impossible to be notified if a user had refunded a purchase. I got that from questions like these:</p>
  <ul>
  <li><a href="https://stackoverflow.com/questions/6439482/how-does-apple-notify-ios-apps-of-refunds-of-in-app-purchases-iap?rq=1">How does Apple notify iOS apps of refunds of in-app purchases (IAP)?</a></li>
  <li><a href="https://stackoverflow.com/questions/53258303/do-i-get-any-notifications-if-my-consumable-iaps-are-refunded">Do I get any notifications if my consumable IAPs are refunded?</a></li>
  </ul>
  <p>Now as of 2020 it seems Apple has finally introduced a <a href="https://developer.apple.com/documentation/storekit/original_api_for_in-app_purchase/handling_refund_notifications" rel="nofollow noreferrer">notification for it</a>. But this sounds like it only works with an <strong>additional server</strong>. I want to make sure I'm not missing something.</p>
  <p>I do not have my own server. Can I still somehow detect refunds using <strong>only local validation</strong> (or a similar concept)?</p>
