So I learned that when you use Client/StartPurchase request and pass in itemId with any currency that is not RM (real money), Playfab gives you a Payment option with purchase provider called "Title[titleId]":
"PaymentOptions": [ { "Currency": "ST", "Price": 100, "ProviderName": "Title123123", "StoreCredit": 0 } ],
I already disabled /Client/PurchaseItem using Client API policy restrictions and all purchases are made using cloud script. I would also like to disable this method of purchasing (for cheaters) while preserving the possibility to buy iAP items with RM.
If there any way to block it?
