Tomorrow I will present Fun and Profit with the Google Checkout API at XML 2006. Checkout is a REST XML + HTTP API relying on Basic Auth over SSL and HMAC_SHA1 signatures for security. It is one of the most simple Google APIs: for level 1 integration all you need is a generated snippet of HTML to include in your page. But for level 2 integration, when you want to integrate your order management system with Google, I consider it the most complex of the Google APIs, because it involves synchronous and asynchronous calls, and is bidirectional.

XML had an interesting history in the past 10 years as a glue between systems. I’m curious to get the audience feedback about wether we should offer a RELAXNG schema for our API in addition to the XSD we provide now.

The conference program is excellent, I look foward to attending the sessions.
