TestLink

I would like to assign requirements to a testcase via the clientAssignRequirements API function, but the function expects the ID of a requirements specication.

Is it possible to get a list of requirement specification ID's by using the API? I really want to automate this, but then I need to know to which requirement spec a requirement belongs.

I would also like to get some API functionality so I can generate a report for the following through a python script:

% Requirements Linked to Test cases
% Req - PASSED
% Req - BLOCKED
% Req - FAILED
% Test cases linked to requirements

Would be really awesome if requirements-related API calls can be implemented.
