Q:

How to add Payment integration for iOS application

I am developing an iOS application in swift, In this application, User can buy the event photos by adding selected photos to cart. Here, How can i proceed with the payment options and do i need to add Apple Pay or In App-Purchase in this scenario? 
I've done some research on this topic and I came to know.
 Apple Pay: Sells physical goods such as groceries, clothing, and appliances.
In-App: Sells virtual goods such as premium content for your app, and subscriptions for digital content.
So, in my application i am thinking about to add In-app purchase. Please confirm me? and help me out.
Thanks in Advance.

A:

Yes. You need to in-App purchase only for digital content-selling. Go with in-app purchase. If you are new to in-app purchase, here is the link to follow.
