Get chat messages for a specific userId

Thanks a lot for the clarification.

yes, I have seen Zoom API errors if I don’t provide to_contact and to_channel parameters on the 2nd endpoint which proves the API description. The same for the 1st endpoint.

Please refer to my recent post for similar questions on how to get contacts with UserIds.

I am not sure how I can get a UserId’s contacts (with to_contact parameter). It looks the endpoint can’t get contacts for each UserId.
