Unfortunately, In-App Purchasing V1 has now been deprecated; you can find further information here.
If you now submit your IAPv1 supported app to the Amazon Appstore, it will be rejected during submission. However, if your app has been developed using Corona, GameSalad, or is an HTML5 web app which all currently rely on IAPv1, please get in touch with the team directly to be flagged for approval if your app is rejected. Ensure you include your app name, app key, live ASIN and the SDK used in your request after you have submitted your app.
