Re: [godot-devel] In app purchase apis

[박한얼 <volzhs@xxxxxxxxx>]

I can work with Android - Google play store.

I've not worked with Amazon IAP.

I think base api should have set_product_info( list ).

because we should know the IDs and inquiry them to get to know it's purchased but not consumed.

then we can make it work like "restore_purchse( product_info )" for iOS.

I think Unity has a sort of universal IAP API, does it not? we could use as reference

I fully agree, if we can have a common base with platform-specific
extensions (kind of how is done for the various flavours of InputEvent
or even the OS singleton), I think it would be cleaner code-wise and
simpler to understand for users (and simpler to document too).

volzhs did some work on the Android IAP, he might be interested. (I
see he's now subscribed to the ML, he wasn't yet when you posted
initially).
