Implementing Apple Pay within apps for payment is a bit tricky, but our book solves this problem for you. Whether you are a brand new iOS app developer or a seasoned expert, this book arms you with necessary skills to successfully implement Apple Pay in your online-payment workflow. Whether you are a brand new iOS app developer or a seasoned expert, this book arms you with the necessary skills to successfully implement Apple Pay.

You will then learn how to determine whether the customer can use Apple Pay, and how to create payment requests. You will come to grips with designing a payment-processor program to interact with the payment gateway. Finally, we take a look at a business-focused view of Apple Pay protocols and classes.

Defining order management data structures

An order management system has, as a minimum, data structures representing products available for sale (inventory) and orders. To support the Apple Pay workflow, the system should also have a structure representing the supported shipping methods. The example project uses a MongoDB database to store this data, and the Mongoose data modeling module for Node.js. MongoDB is a document-based database system. Mongoose makes it easier to create documents from schemas and access the data in these documents.
