At a Glance
At a high level, the interactions between the user, your app, and the App Store during the In-App Purchase
process take place in three stages, as shown in Figure I-1. First, the user navigates to your app’s store and your
app displays its products. Second, the user selects a product to buy and the app requests payment from the
App Store. Third, the App Store processes the payment and your app delivers the purchased product.

Understanding what kinds of products and behaviors are supported by In-App Purchase lets you design your
app and in-app store to make the best use of this technology.
Relevant Chapter: “Designing Your App’s Products” (page 8)
Your App Interacts with the App Store to Sell Products
All apps that use In-App Purchase need to implement the core functionality described in these chapters to let
users make purchases and then deliver the purchased products.
These development tasks need to be done in order. The relevant chapters introduce them in the order you
implement them, and they’re listed in full in “Implementation Checklist” (page 42). To help plan your
development, you may want to read the full checklist before you begin.
