I am getting the below error

code 3000: “You have reached the limit for the number of attendees you can add. Contact Zoom Support for more information.”

I have more than 100 accounts of Webinar & meeting of 500 participants

When I add a registrant using Pabbly or Zapier into Zoom as Webinar Registrant then above error is occuring.

Need help.
