Amazon.com has introduced an In-App Purchasing (IAP) service which will enable Amazon Appstore developers to offer digital content and subscriptions for purchase within apps and games that are available on Kindle Fires and other Android devices.

The new service will enable developers to integrate and monetise their apps and games, while offering customers a secure 1-Click purchasing experience.

In-app purchasing will allowing app developers to cash in on their existing userbase as it is already a popular feature on iOS and Android devices.

Amazon Appstore’s In-App Purchasing API has already been integrated by the developers including ZeptoLab, Disney, Glu Mobile, Storm8, Social Gaming Network, Gameloft, G5 Entertainment and publishers like Condé Nast, The Wall Street Journal and New York Post, offering millions of Amazon customers in-app content and subscriptions.

Amazon Appstore director Aaron Rubenson said Amazon Appstore’s In-App Purchasing service enables developers to generate more revenue from the apps.

"In-App Purchasing is simple to integrate and gives developers access to millions of Amazon customers who are already familiar with Amazon’s 1-Click payment system," said Rubenson.
