For the moment my app is published on Android (google play store) and IOS and I have a php script that validate the receipts from the UnityPurchasing module that validate payments and deliver items to the users.
I would like to do the same to validate UDP payments, I see in the doc that I can call the url:
/udp/developer/api/order?orderQueryToken=&sign= to validate it but it’s not a valid url it’s missing the domain…
Or do I have to implement the callback system to make it work ?
(note I would prefer to use UnityIAP system than UDP package)
So I put my callback script in a file named index.php and point the callback url to the directory https://game.mydomain.com/UDP_callback/, now the setting is well saved but the callback is never called…
For information I didn’t publish the app yet, I just try in sandbox mode but it have to work in sandbox mode too no ?
Would like to check do you still have problem for the server side callbacks implementation? We have some updates since your enquiry last time and it might worth to take a look at our latest documentation.
As UDP was still in preview and laks some testing stuff I didn’t use it for my game.
Maybe I’ll try it on an other game as it’s now a validated package.
Thanks for the update.
