I just installed moodle 2.0 (preview 3) and started to play around with wweb services...
I had no problem to setup the web service and its authentication, but when I went to add function I found only about 15 of them.
It's what we got?
I understood that 'all' the api will be accessible via web services...
Did you ever get a solution to your web service requirements? I too want to do this but is it a case of using 1.9?
