I'm currently trying to figure out how to do in-app purchases for real money (not virtual money) with Unity for an app I'm planning to release to both Android and iOS.
Everything else in the API seems straight forward, I've read through the cart section of the API and tested out the store widget for Unity but it seems these aren't what I'm looking for. I can see there's a widget that allows IAP for iOS but there isn't the same widget for Unity.
Is IAP functionality for Unity built into the API? Could you let me know how I can go about doing IAP with Unity for both Android and iOS?
