Hi,
I am currently developing an app for telecommunication services, being placed somewhere in the middle between a digital and a physical service. I want to make it possible to buy top-ups through the (principally free) app. Now I am not certain, which options for payment apply to me: if I need to use, or if I am even allowed to, use apple's in-app payment.
Can anyone recommend a company specialized in interpreting the developer guidelines, who I could contact to review the app flows and screens already in an early stage of development, or, has anybody another idea how I should approach this?
