About the In-App Purchasing API

The In-App Purchasing (IAP) API makes it easy for you to offer digital content and subscriptions for purchase within your app, such as in-game currency, expansion packs, upgrades, magazine issues, consumables, and more. You can quickly be up and running, ready to give millions of Amazon customers the ability to purchase engaging digital content using Amazon 1-Click settings.

In-App Purchasing handles the details of purchase flow, payment processing, receipts, and rights management for the purchasable content. With unique receipt identifiers, the IAP API enables you to easily ensure that customers receive purchased in-app items quickly, as well as track transactions and fulfillment.
