Google to make in-app payments open to all web application developers
Google has rolled out its in-app payment service for any web developer to integrate with their web apps wherever they’re hosted, including the Chrome Web Store.
The service enables developers to offer single-click payments from their applications. In order to sign up for Google's in-app payments, developers must be Google Checkout members. 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.
Consumers buying the goods in-app can also pay for goods via their Google accounts. 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 the app in minimal steps.
The service was initially announced at the Google's I/O Conference in May 2011. Google is charging a 5 percent share of revenue.
