Apple Pay transaction fees

Are there any fees involved with using Apple Pay in an app I would like to develop for a rental service? For example, my tenants would use Apple Pay on the app to pay their rent.

From my understanding, using Apple Pay to make a transaction has no commission fees, however, some online sources state that there is a 0.15% charge for payments made with Apple Pay. I also understand that in-app purchases have a 30% fee, but I would not be using this feature as my app will be selling a service.

Thank you very much.
