Transaction data not returned for iOS

[lozan]

In my application I am using the purchase receipt for verification. However, if I make a purchase on AppStore I am only getting TransactionDataSignature and getTransactionData() always returns null.

This is unusable in my case, because the users cannot get what they paid for without verification on my server. With getTransactionDataSignature I can bet the base64 encoded signature, but as I said, in my case (any many others) it's useless.

By the way, this is for MOE, not RoboVM

We currently have no app with MOE running with gdx-pay.

Have you tried debugging the issue yourself?

It is not hard to do that. Steps:

• Clone gdx-pay repo.
• Follow steps: https://github.com/libgdx/gdx-pay/#using-gdx-pay-locally-build-binaries-in-a-project
• In class com.badlogic.gdx.pay.ios.apple.PurchaseManageriOSApple, put some logging statements around line 282

Probably there is something wrong with these statements:

    if (payment.requestData() != null) {
        final String transactionData;
        transactionData = payment.requestData().base64EncodedStringWithOptions(0);
        transaction.setTransactionData(transactionData);
    } else {
        transaction.setTransactionData(null);
    }

It seems that your implementation is good. My bad. At my validation server we used https://developer.apple.com/documentation/storekit/skpaymenttransaction/1617722-transactionreceipt

However, that function is deprecated since iOS 7 (although it still works on iOS 11). So, we'll update the server-side implementation. I don't see a point in adding that transactionReceipt in gdx-pay.

Thanks

By the way, In case you need a validation for the MOE implementation, it does what it's supposed to and returns the correct data. there's just no way to get the transactionReceipt property of SKPaymentTransaction, and that was my issue.

Thanks for responding, closing issue

Hi Guys. Experiencing now the same issue with the 1.0.0 version and RoboVM. payment.requestData() is always null.

Do you have any ideas? With the previous version, everything was ok .
