API and Webhooks Webinars
1

We are experiencing an issue with our Zoom Pro account, which includes a webinar license supporting up to 500 attendees.

When we try to add registrants via the API (POST /webinars/{webinarId}/registrants), we consistently receive the following error:
data: {
code: 3000,
message: ‘You have reached the limit for the number of attendees you can add. Contact Zoom Support for more information.’
}

This happens even when:

  • Creating a brand new webinar for testing
  • Using a brand new email that has never been used

We’ve verified that:

  • Webinar registration is enabled
  • The host has a 500-attendee webinar license
  • All request fields are valid

Note: webinar still can do registration and join with original zoom registration link.

@chunsiong.zoom, I am in the same team as the original poster. Could you please help us to solve this problem as we have many webinars lined up over the coming days.
