Amazon’s Appstore has offered a typical application acquisition experience, save for one important detail: in-app purchasing. Beginning today, devs can now take advantage of the familiar revenue booster already available in the iOS App Store and Google Play, through the use of the Amazon Appstore In-App Purchasing API. The service will enable Android device and Kindle Fire users to pick up expansion packs, virtual gaming currency or manage subscriptions from within individual applications, with the same one-click purchase experience available in Amazon’s online store. A handful of top devs like Disney and Conde Nast have already hopped on board, but those of you who haven’t received an early nod from AMZN can now join in on the fun as well. Click past the break for a brief video intro from the e-tailer, along with a handful of testimonials in the full press release.
