The link you referenced has a pretty nice walk through of authentication. What it doesn't mention though, is the /auth.xml URL on line 5 of the first code block actually returns a nice list of their 'undocumented' apis. The particular one you are looking for is: /my-site-name/workbooks?format=xml. You should also checkout Power Tools for Tableau . We've got a lot of tools that make great additions to your workflows for both tableau server and desktop.
