Apple Pay or in-app purchases for mobile application payments
Apple Pay and in-app purchases are used differently, depending on the type of purchase.
Apple Pay should be used to sell physical goods such as groceries, clothing, and appliances. Apple Pay is also recommended for services such as club memberships, hotel reservations, and tickets for events.
In-App Purchases should be used to sell virtual goods such as premium content for your app and subscriptions for digital content.
