Which one you recommend for integration for the below use case and why?
1. User should be able to schedule a meeting
2. Once the meeting is created I would like list out the user the meeting details like Join URL, Host URL, Meeting key and meeting pwd.
XML API allows you much more control over scheduling and data retrieval, and should be the first choice for any new WebEx API development. It also allows you to build your application outside of the web browser, so that sensitive information can be sent using server to server communication that can't be packet sniffed from a local machine.
