Device type of "Unknown"

I am seeing mostly “Unknown” when I use the “List Meeting Participants” API. I found 2 existing posts with the same issue but no details on how to resolve it:

As far as I can tell, the API call is successful but the device for participants is always “Unknown”. Is there a reason for this? I am using JWT auth with this API:

{{baseUrl}}/metrics/meetings/:meetingId/participants?type=past&page_size=30

Thanks,

Pete

Hi @pete_h
Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!
Could you please share the meetingID that you are using as an example to query the Get meeting participant endpoint so I can look into this issue.

If you could also share the response body that you get (just make sure to not share personal data such as email or user ids)

Thanks
Elisa

Meeting UUID is J31RP1jtRdy06OnBrkNVnQ==

Thanks @pete_h I am looking into this and will bring you an update shortly
(ZSEE-55736 Internal ticket for reference)

Hello @pete_h

Thanks for your patience while I investigated this issue further.
I just heard back from our team and this is expected when the participants that joined the meeting did not sign into their Zoom accounts to join the meeting so they are identified as guests, hence the device type is “unknown”

Hope this helps,
Elisa
