Does Apple charge for Paypal transactions?

Question

I want to integrate Paypal payment gateway in my iOS application but before that I want to know that "does Apple take any fees for the transaction as I am doing it through Paypal and not the In-App Purchase?". I know that Paypal take around 3.50% + $0.15 for each transaction.

Answer 1

Apple takes 30% of any transaction done with their StoreKit. They do not take any percentage of any other payment system.

But most importantly, you can not use any other payment system than Apple's own system for digital goods. So Paypal can only be used for physical goods like Food delivery, clothes, ...

Any digital goods like e-books, music, video, passes for services, etc have to bought via Apple's StoreKit.
