Today at Google I/O, we launched the developer API of
      
Google In-App
      Payments for the web. In-App Payments enables any web application to receive
      payments from users and keep them engaged in your application. It is available to all US
      developers in sandbox today and will be followed by a consumer launch and an international
      rollout over the summer. 
The team started building Google In-App
      Payments soon after Jambool was 
acquired
      by Google in August 2010. This project brought Social Gold technology and expertise
      and combined it with Google scale. For the payments platform that we’re announcing today, the
      theme is simplicity:
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 have 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 are no fixed
      purchase fees, setup costs, or monthly minimums. 
The JavaScript
      version of the In-App Payments API is available to developers today. A Flash version of the
      API will be available in the coming weeks.
We invite you to 
sign up, start
      integrating your apps and 
send
      us feedback. Let’s work together to delight consumers this summer with amazing web
      apps, monetized effectively, all in the app.
