Hello,

I am using the Webinar API to retrieve a list of all absentee and registered users. Fetching all webinars and registrants works fine and returns no errors. However, when I try to retrieve the list of absentees, I receive the following error:

“response”: string “{ “code”: 3001, “message”: “Meeting does not exist: [UUID].” }”

Here are the API calls I made that returned the error (I’ve replaced the actual UUID with “[UUID]” for privacy in this message):

[https://api.zoom.us/v2/past\_webinars/[UUID]/absentees](https://api.zoom.us/v2/past_webinars/%5BUUID%5D/absentees)  
[https://api.zoom.us/v2/report/webinars/[UUID]/participants](https://api.zoom.us/v2/report/webinars/%5BUUID%5D/participants)  
[https://api.zoom.us/v2/report/webinars/[UUID]](https://api.zoom.us/v2/report/webinars/%5BUUID%5D)

When I check the list of all webinars, I can confirm that the webinar in question exists, so I am confused as to why I’m receiving this error.

Could you please assist me in resolving this issue?

Thank you in advance for your help!

Hi,

This may be happenig because the webinar has not ended yet.  
Calling the “Get/past\_webinars/{webinarUUID}/absentees” etc etc endpoints should only be done once the webinar has completed.

FYI you could check through webhooks whether a webinar has indeed finished before attempting to retrieve absentees

Hope this helps!

Cheers,

Hello,

I’ve reviewed the webinars, and most of them have already concluded—specifically, some were finished in November and December of last year.

Thank you,
