I have searched a lot and cannot find the answer to how the App Store will take a commission from my app. The app allows users to expand their profiles and gain a large number of followers, and in the future, they can sell their shows, such as stand-up performances, singing, scientific lectures, or even business or cooking courses in live broadcasts. They can choose to have a regular free broadcast or a paid broadcast that requires payment for access. The payment works as follows: User 1 funds their internal account in the app and then can transfer money to another user, User 2, for access to their live broadcast. For this transaction, the app will take a 5% commission for using its platform. The user is essentially purchasing a ticket to enter the show or lecture, and it is a one-time payment. Here’s my question: Will Apple take a 30% commission from the 5% that the developer earns, or will it take the 30% from the total amount transferred from User 1 to User 2?
You need to answer the more fundamental question of whether in-app-purchase is allowed for this at all.
If in-app-purchase is allowed, Apple takes 30% (or 15%) of the total value of the transaction, as well as any applicable taxes. If in-app-purchase is not allowed, you need to provide your own payment processing and Apple take nothing.
As to whether in-app-purchase is allowed, the primary question is whether the purchased content is delivered in the app. You talk about "shows" and "lectures", but I take it that these are actually streamed videos; are these presented in your app? I'm not totally familiar with the current rules in this case; I think there are some relatively new exceptions for one-to-one consultations.
