Check your IAP implementation

For implementation via the UDP Package

The UDP Package implementation requires that you explicitly

• initialize UDP
• query the store’s IAP inventory
• request to purchase a product
• consume the purchase

as explained in this section of the UDP Documentation.

Please read carefully and ensure your implementation is compliant. Again, test your IAPs in your generic UDP build before repacking it for submission to the stores.

For implementation via Unity IAP

The following steps: initialize UDP, query the store’s IAP inventory, request to purchase a product, consume the purchase - need NOT be specifically implemented for UDP because your game relies on the underlying Unity IAP implementation.

However, your game needs to properly use Unity IAP’s similar functions (initialization, purchase, etc) according to the Unity IAP Documentation.

(Note that the steps involved are a little different between UDP and Unity IAP. For example, Unity IAP does the “consume” automatically, so there is no API in Unity IAP for the consumption.)

Again, test your IAPs in your generic UDP build before repacking it for submission to the stores.
