Apple Pay is a secure, easy way to make payments for physical goods and services, as well as donations, in iOS apps, in watchOS apps, and on websites. Users authorize payments and provide shipping and contact information, using credentials that are securely stored on the device.
Tip It’s important for app developers to understand the difference between Apple Pay and In-App Purchase. Use Apple Pay in your app to sell physical goods like groceries, clothing, and appliances; for services such as club memberships, hotel reservations, and tickets for events; and for donations. Use In-App Purchase in your app to sell virtual goods, such as premium content for your app, and subscriptions for digital content.
