PurchaseToken is always NULL in the iOS plugin

[jahlen]

Hi,

I was trying to implement server side verification of iOS InApp purchases, and never was able to get anything but NULL in the PurchaseToken.

I checked the source code and noticed that the PurchaseToken is never set from either InAppBillingImplementation.PurchaseAsync or InAppBillingImplementation.ToIABPurchase.

Probably this is because there is nothing called PurchaseToken in iOS, but instead a TransactionReceipt (which can be validated server side against https://buy.itunes.apple.com/verifyReceipt or https://sandbox.itunes.apple.com/verifyReceipt).

I see that the IInAppBillingVerifyPurchase callback is passed a receipt, but that is the receipt for the app (NSBundle.MainBundle.AppStoreReceiptUrl) instead of the InAppPurchase receipt.

Suggestions

• Pass the TransactionReceipt in the PurchaseToken field
• In the IInAppBillingVerifyPurchase callback, make sure to pass the TransactionReceipt from the InAppPurchase, not the app

I can provide the code changes if that helps.

Kind Regards
Johan

Hi James,
Thanks for quickly changing this. However, the PurchaseAsync method also needs to be updated.

Hi James,
Any chance you will update the package on NuGet soon? It's still version 1.2.5 (from before this change).
Thanks!

Note that TransactionReceipt is deprecated!

Apple recommends using the mainBundle's appStoreReceiptURL instead.
