• The request message that was being returned gave "BadRequest" as the reason for failing.
• At first I thought it was because i was using an async call in a background worker. So I moved the code out of the background worker and into the controller to process real time. The background worker was in a winservice and operates independently of the website.
• Next after a lot of time, and learning a lot about the Zoom API, I figured it out. It was to do with the json body passed to the API. Specifically the recurrence class. I filled it to have a recurrence of 1 and zoom took the request and posted the meeting returning success.
