The developer API of Google In-App Payments for the web was launched today at Google I/O, and enables any web application to receive payments from users and keep them engaged in your app.
“The simple API makes integration fast so you can start getting paid sooner. Implementing In-App Payments requires only two API calls: one to initiate the payment, and one to accept the notification when a payment is made.”
“The simple user experience will let your users pay without leaving the app or entering billing details. Users who’ve previously completed a purchase on Google Checkout, Android Market, Google eBookstore, YouTube Movies and more can use that same account to pay for items in your app in minimal steps. Fast payments that keep users in your game or site can boost customer conversion rates, increasing your revenue.”
“The simple pricing model is a flat payment processing fee of 5%. It’s 5% whether you distribute your app yourself or via the Chrome Web Store. There’re no fixed purchase fees, setup costs, or monthly minimums.”
