Amazon has launched an in-app purchasing service to 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.

Amazon says the service is simple for developers to integrate and helps them to monetize their apps and games, while offering customers a secure 1-Click purchasing experience. Developers and publishers that have integrated the in-app purchasing API include Disney, Glu Mobile, Gameloft, Condé Nast, The Wall Street Journal and the New York Post.

“Amazon Appstores in-app purchasing service enables developers to generate more revenue from their apps,” says Amazon Appstore director, Aaron Rubenson. “In-app purchasing is simple to integrate and gives developers access to millions of Amazon customers who are already familiar with Amazons 1-Click payment system. Many of Amazon Appstores customers have shopped with Amazon before and they trust Amazons easy payment process, which leads to higher conversion of developers in-app content and subscriptions.”
