# PassKit Accept Apple Pay payments for physical goods, real-world services, donations, and eligible recurring payments, and add passes to the user's Wallet. Covers payment buttons, payment requests, authorization, Wallet passes, and merchant configuration. Targets Swift 6.3 / iOS 26+. For advanced Apple Pay flows, one `PKPaymentRequest` can set only one optional advanced request type: recurring, automatic reload, deferred, Apple Pay Later availability, or multi-token contexts. Use separate payment requests when a checkout needs more than one of those modes. ## Contents - [Setup](#setup) - [Displaying the Apple Pay Button](#displaying-the-apple-pay-button) - [Creating a Payment Request](#creating-a-payment-request) - [Presenting the Payment Sheet](#presenting-the-payment-sheet) - [Handling Payment Authorization](#handling-payment-authorization) - [Wallet Passes](#wallet-passes) - [Checking Pass Library](#checking-pass-library) - [Common Mistakes](#common-mistakes) - [Review Checklist](#review-checklist) - [References](#references) ## Setup ### Project Configuration 1.
