Payment through the processing center in a native mobile application?

Question

Android

There are two apps for anroid/ios. The functionality is the same. On the site it is possible to pay by credit card / electronic money through the processing center (Uniteller). How can user-friendly payment be implemented in the mobile application as well? Can it be done here and there?
Maybe someone has experience? Thank you.

Answer 1

I haven't personally used it, but I know that some processing providers provide SDK for different platforms, for example www.payonline.ru/developers/SDK
Check yours, maybe there is something similar too.

Answer 2

If you are buying non-physical goods, then you need to use only the Google / iOS payment system. This is written in the guides.
