Google Checkout

Google Checkout provides a streamlined e-commerce checkout process that can be integrated with Google AdWords and Analytics to attract more leads and drive better conversion rates. The Checkout API allows you to integrate your site with Google Checkout, either by spending 5 minutes and dropping in simple "Buy Now" buttons, or by stepping through a complete integration of your order management system with Checkout. It's a message-based REST XML API involving synchronous and asynchronous interactions between Google and the merchant's server.
