981235 - fxpay: check for product ownership (i.e. validate in-app receipts)

Status: RESOLVED FIXED

(Marketplace Graveyard :: Payments/Refunds, defect, P2)

Description

[Kumar McMillan [:kumar]]

The fxpay script needs a method that an app can call to answer 'does the user on this device already own product ID 123'?

Under the hood this will use the apps API to check for and validate receipts.

Would that mean the app could then decide to allow a duplicate payment or not? Some in-apps could be made multiple times, others not, others might have some app logic that makes sense to the app.

Hmm, if an app were to allow duplicate payments then that might get messy because fxpay would install multiple receipts (I think?). Maybe we need to add a 'quantity' field to the receipt to accommodate buying multiple Unicorns or whatever.
