Hi @ttmyint ,
This is a known occurrence. It seems there were some API changes made where this info will not be returned unless the participants are on the dev’s account. I’m still awaiting more information, but here is the most recent change log release: https://devsupport.zoom.us/hc/en-us/articles/13573564717581-Zoom-Meeting-API-February-25-2023
Here’s a short thread on this for more info: Meeting participants report not returning IDs for participants - #3 by gianni.zoom
