My App requires video calling between two users. Before they can do that they have to pay some amount and then the video call can be connected inside the app.
After reading the Apple guidelines for In-App purchase, I'm little sure that my app falls in the In-App purchase and other transaction methods such as PayPal cannot be used here.
Question
Is it fair to use PayPal or other services like Stripe/PayPal to get the payment from user or I have to use In-App purchase?
