Is it mandatory to use in-app purchases for video consultation?

I am developing an iOS application for pet owner and veterinary doctor in which pet owner would consult with doctor through video/audio call and there also will be consultation charges.

Can I use stipe payment integration or I have to integrate in app purchase?
