New to web services?

Web services are web-based applications that use open, XML-based standards and transport protocols to exchange data with clients. You do not need to know what kind of programming language is being used, or the internal data structure. You can request data from a web service using simple HTTP-GET requests or more complex SOAP calls. Data is returned in XML or any other open standard.

We created a small tutorial on how to consume a web service, one on website thumbnails and a step-by-step one with the free HQAPI example API. If you are new to web services, check them out.
