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:
- How does Apple notify iOS apps of refunds of in-app purchases (IAP)?
- Do I get any notifications if my consumable IAPs are refunded?
Now as of 2020 it seems Apple has finally introduced a notification for it. But this sounds like it only works with an additional server. I want to make sure I'm not missing something.
I do not have my own server. Can I still somehow detect refunds using only local validation (or a similar concept)?
