Hi, we were just going through documentation related to webhooks and we have noticed that in meeting.participant\_joined (and other similar webooks) webhook payload it is mentioned that `id` key in participant object will be removed in future and instead we have to use `participant_user_id` to get the value, Now during testing we have observed that for some users we are getting UUID value against both keys and for some we only get it against `id` which will get removed in future according to document. Can anyone please tell why there is this difference in responses.  
Thanks

Hi @zawar.ahmed

Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!  
I was able to do some testing on my end and I can confirm that the “participant\_user\_id” along with the “id” from the participant object, they have the same value. I can also confirmed that the user associated with those ids was logged in into their Zoom account when I did the testings.

The id value will be empty if the participant did not log into Zoom when joining the meeting.

Hope this helps,  
Elisa

Thanks @elisa.zoom for looking into the issue.  
I tried with 4 zoom clients on which 4 separate users were signed in, but i only got value for both these fields for 2 users only for other 2 i received only `id` this is what confusing me that why there is different response for these users.

Thanks once again.
