Unity IAP and server side validation ?

Is it possible to use the easy implementation from unity iap & some kind server side validation ?
As far as i know unity iap doesnt offer a server side validation... but is it possible to receive the recipe key from unity iap, send it to the server and use the ( for example ) google api to validate the key ?

 

yes, we do this in our games, you need to implement "public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs e)"

Do a client side validation (if you want), the receipt is sent in the arguments:
e.purchasedProduct.receipt

You would need to send this receipt to your backend, alongside with platform information and do the validation and currency redemption there.

 

Great thanks a lot !
