Hi @RudySeidinger , Happy to help! The List Participants documentation you shared is for past webinars. I just want to confirm whether you are looking for the userId for past or scheduled webinars? For scheduled webinars, these are the endpoints that might interest you: [https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrants](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrants) [https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantget](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantget) Here’s also some clarity on participantId vs. userId: > [@What is the difference between id and user\_id](https://devforum.zoom.us/t/what-is-the-difference-between-id-and-user-id/12681/2): > > participant.id === if participant is a registered Zoom User, it is that user’s ID (if they’re logged into Zoom, IIRC) participant.user\_id === participant’s unique identifier for this specific single meeting (this may display as a phone number for dial-in users) I found some related information in this post that might be helpful: [Unable to map meeting registrant id with live participant id](https://devforum.zoom.us/t/unable-to-map-meeting-registrant-id-with-live-participant-id/6862) Thank you, Gianni --- _[View the full topic](https://devforum.zoom.us/t/fetching-userid-for-a-scheduled-webinar/60476)._
