Apple Pay is a payment system designed for Apple products such as the iPhone, iPad, MacBook Pro with Touch Bar, and Apple Watch. It supports NFC payments (card present), in-app purchases (card not present, requiring a native iOS app), and browser-based solutions through Apple Pay Web.

For in-app purchases on iOS, a native app is required, and browser-based integrations can be set up using Apple Pay Web. Technical documentation and client-side integration guides are available directly from Apple.

To process Apple Pay transactions, a payment processing certificate is needed, which can be created through Apple's developer platform. This certificate is required for both native apps and web-based transactions.
