im currently working on ue4 playfab iap validation.
i can find receipt data from ue4 iap info
but there's no signature whrre is it?
or is it transaction identifier?
and i printed receipt data and it seems no problem
but error code says invalid receipt
According to the known case -- https://community.playfab.com/questions/45680/invalid-receipt-response-to-validate-google-play-p.html, you can get the data { "receiptData": "xxx", "signature": "xxxx" } through getting InAppPurchaseReceiptInfo.ValidationInfo. Then you need to decode the receiptData that be encoded in Base64 to allow you pass it as ReceiptJson. You can also refer to this answer -- https://community.playfab.com/answers/46085/view.html for the solution of CPP.
