Is there any documentation that would help me get started using the SOAP API? I will not be using a library such
as PHP, etc, just making direct http posts from a C program using libcurl. I have done this before with Exchange Web Services, but with Zimbra I'm not sure how to get started - what URL do I post to? What is the Authorization token and how do I get one? Specific examples of how a POST should be formatted would be very helpful.
