TestLink

Why not going through the UI?
It is available on the "Personal" menu, just next to Logout. From there you can generate or access your dev key.

Just make sure you enable the api in config/custom_config

You can get the list of functions by directly looking at the xmlrpc server server source located here lib/api/xmlrpc.php
it will define a mapping between function names and functions to call in the server constructor. Look for the assignment of "$this->methods".

I don't know if this is sill needed or if this is going to help, but in order to make the "Execute and Save Results" button work, you could try to: Create and assign some speciffic custom fields to let TestLink know which xmlrpc server to contact. See function getXMLServerParams() in cfiel...
