I am trying to make IAP in unity using redeemAppleAppStoreinventoryItems for validation of receipt after following integration https://learn.microsoft.com/en-us/gaming/playfab/features/economy-v2/tutorials/marketplace-integrations/google and also the validation https://learn.microsoft.com/en-us/gaming/playfab/features/economy-v2/tutorials/marketplace-redemption/google
I am getting the "errorMessage": "Marketplace returned HTTP status code 'GetInAppPurchasesFailure'
the app store is also set up with correct product ID and mapped in the playfab bundle
after using the IAP of unity the receipt is recieved is receipt : {"Payload":"ThisIsFakeReceiptData","Store":"fake","TransactionID":"825ccd33-f7a8-4188-9af7-32ab9a0f8167"}
also the unity is switched to IOS platform there are very few post for Apple store validation so i couldn't figure it out. any solution?
