Announcing the In-App Purchasing API for Kindle Fire and Other Android Devices

Announcing the availability of our Amazon Appstore for Android SDK and In-App Purchasing API to our developer community. The In-App Purchasing API enables you to offer digital content and subscriptions--such as in-game currency, expansion packs, upgrades, and magazine issues--for purchase within apps. 

We created the In-App Purchasing API to make it easy for you to increase customer engagement and monetize your apps on Kindle Fire and other Android devices. With the Amazon Appstore for Android In-App Purchasing solution, you can reach customers with existing accounts who have already bought apps, including millions of Kindle Fire customers. Our simple, secure, and trusted 1-Click purchase experience is easy for customers to use, increasing conversion rates for purchases within your app. Plus, we designed our in-app purchasing (IAP) solution to be simple and easy to integrate so you can be up and running quickly. 

It’s easy to get started from the Amazon Appstore Developer Portal, where you'll find documentation, sample code, tutorials, frequently asked questions, and more.  In the coming weeks, we’ll also be featuring strategies and tips from in-app purchasing beta program partners, such as Glu Mobile, G5 Entertainment, Storm8, and New York Post, here on our developer blog. You can also learn more about our IAP solution from our Introduction to IAP video.

What do our beta program partners say about IAP on the Amazon Appstore for Android?

“Storm8 coordinated closely with Amazon’s team during the initial launch of its IAP beta test, and within two months of integration, we saw revenue grow by tenfold from our game,” said Perry Tam, CEO and co-founder at Storm8, producer of games such as Restaurant Story, Bakery Story, Farm Story, and Fashion Story. “We immediately brought over additional Storm8 games, and in two weeks, not only did our revenue continue to grow, but we had four of the top five free apps in the Amazon Appstore. With the tremendous initial success, we definitely plan on continuing to invest in the platform and can't wait to bring additional Storm8/TeamLava games to Kindle Fire and Amazon users.

“Amazon's in-app purchasing solution created a great way for us to reduce friction and drive more revenue from our games, as millions of people already have Amazon accounts,” said Michael Ritter, senior vice president Licensing & Distribution at Social Gaming Network, maker of Warp Rush, Dress Up! Fashion, Bird's the Word, and Night of the Living Dead Defense. “Kindle Fire already has a well-integrated storefront and marketplace to distribute mobile games. By enabling in-app purchases we are able to be more flexible in pricing. We can release free games, provide updates, and enhancements, and continue to monetize.”

“We found that by offering a product with IAP, rather than other monetization types, our conversion rates went up as did our revenue on a per title basis,” said Larissa McCleary, director of marketing at G5 Entertainment, Inc., creator of Virtual City Playground and Mahjong Artifacts. “Although our experience on Amazon has always been great, we are thrilled now that IAP is available. This will allow us to continue our business model, but also to allow other developers to partake as well. Eventually, if more and more developers participate, we think we will experience even higher conversion rates, since players will be more familiar with what IAP is and how it functions, making the play experience even more engaging.”

We look forward to seeing how you integrate the API into your apps!
