How To Reproduce

@largeclass Hope you will be fine.

Are you following

  • Rate Limit :point_down: 10 req/sec with Pro Plan & 40 req/sec with Bus+
  • Use this API to register up to 30 registrants at once for a scheduled webinar that requires registration.

Please reply if any query still. Thanks

Yes i’m following 10 request / sec rate limit although i’ve business account.

But i’ve got this issue for a single request as well.

@largeclass what limit you have with Webinar Registrants?

Once you face code:3000 then please try to request /webinars/{webinarId}/registrants and compare your limit and registrants count and calculate if is there any registrant limit available or not.

Possible code:3000 in response

@freelancer.nak We have limit of 500 attendees but not on number of registrants and also when creating webinar we are giving registrants_restrict_number = 0 so that there is no limit(max - 20000 as per zoom) in number of registrations via API. Also we are unable to register in webinar having 0 registrants.
