Get max capacity of registrants for meeting/webinar

I’m working on a website where we show our meetings and webinars and want to indicate to the user how many “seats” are left. From the zoom portal we can set a max number of registrants for a meeting/webinar, however, there doesn’t seem a way to get this number back from an API.

ou’re right, Zoom’s API doesn’t directly provide “seats left” information. Here’s a solution:
Use Zoom’s Get Registrant Report: This API call retrieves a list of registrants for a meeting/webinar.
Compare Registrant Count to Max: In your code, compare the number of registrants retrieved from the Get Registrant Report with the maximum number of attendees you set in the Zoom portal.
Calculate Seats Left: Subtract the number of registrants from the maximum number to determine the remaining “seats.”
This approach gives you the dynamic “seats left” information for your website.
