This guide describes the process of setting up the Amazon Appstore for use with the Unity in-app purchasing (IAP) system. This includes establishing the digital records and relationships that are required to interact with the Unity IAP API, setting up an Amazon developer account, and testing and publishing a Unity IAP application.
As with other platforms, the Amazon store allows for the purchase of virtual goods and managed products. These digital products are identified using a string identifier and an additional type to define durability, with choices including subscription (capable of being subscribed to), consumable (capable of being rebought), and non-consumable (capable of being bought once).
There are cross-store installation issues with publishing to multiple Android IAP stores (e.g. Amazon and Google) simultaneously and shared Android bundle identifiers. Please see the page on Cross-store installation issues with Android in-app purchase stores to learn more.
For non-FireOS Android devices, download and install the Amazon Appstore.
On FireOS devices, the Amazon Appstore should come pre-installed.
Once you have installed the Amazon Appstore, install the Amazon App Tester.

Setting up to use Unity’s IAP takes a few steps.
Import the Unity IAP plug-in. See Setting up Unity IAP for more information (Unity 5.3 or higher).
Set the IAP target store. You should already have an Android app set up. Set the target store using Unity IAP’s Window > Unity IAP > Android > Target Amazon menu item. This is used to toggle between Google, Amazon, and other Android stores.
Alternatively, call the API:
It’s not necessary to download Amazon’s native IAP plug-in when preparing to use the Amazon stores, as all of the functionality it provides is already included in Unity’s IAP service.
Add your app. From the Amazon Developer Portal select Add a New App.
Set up your catalog. Using the product descriptions you prepared earlier, add the items to the Amazon catalog using the Amazon Developer Portal. Navigate to your app’s page, and find the In-App Items section. Use the Add a Consumable, Add an Entitlement, or Add a Subscription buttons to set up your catalog.
