You have reached the limit for the number of attendees you can (Error ‘code’: 3000 )

API and Webhooks Webinars

I am currently encountering an issue while attempting to register attendees for a webinar using the Zoom API. Specifically, I am receiving the following error:

{'code': 3000, 'message': 'You have reached the limit for the number of attendees you can add. Contact Zoom Support for more information.'}

The solutions mentioned in earlier discussions aren’t relevant to us
because of the following reasons

  1. I’ve disabled the mails that goes from zoom.
  2. We have our internal function which sends the calendar invite to the attendees
  3. We have a limit of 500 attendees and for that webinar but there were only 371 registrants

Hi @operations_zoom1 , can you please hit the Get Webinar endpoint and share the registrants_restrict_number response value?

Here’s the settings from that endpoint
the registrant_restrict_number is 0

Hmmm okay! @operations_zoom1 , can you try to register the users again today? I wonder if there was a rate limiting issue unexpectedly hit that fired the (unexpected) error. I think that has happened before.

We’ve registered the users to the upcoming webinars
that worked and even now webinar registrations are happening.

but on 16th of September 26 leads got affected because of this and we wanted to know the exact reason on when and why this error message occurs so that we don’t miss any leads in the future.

7

I need to retrieve data on participants and other details from previous Zoom meetings. Using Zoom reports, we can only access data from the past month. Is it possible to retrieve data older than a month through API integration, or is there another way to get this information?

@gianni.zoom
Kindly respond on how we can avoid this error
We cant afford to miss any leads from registering for the webinar

@operations_zoom1 it may have been a one off error if it is not happening again. Do you have the zm-tracking-id from the failed response header? We can look into the trace error.

Hi @pranjalthakare2019 you can access up to 6 months from the day you submit the query. If you are having an issue, please create a separate post as this thread is not related to what you’re trying to accomplish.

@gianni.zoom
We’re not logging the headers and even zm-tracking-id is not in our logs
but we have to exact time the issue occurred

These are the few timestamps at which this error occurred

Hi @pranjalthakare2019 in order for us to trace the error on our end, we need the value from zm-tracking-id that’s returned in the zoom response headers. You can also test the request in Postman and get the headers there if you are not tracking in your personal configuration.
