**Description**  
I want to get at least webinar participant email, ideally other custom data.

We run webinars without requiring _your_ pre-registration (but we send individual invites and reminders, and we have PII in our system). I understand you still collect name/email at time user joins the webinar.

Using OAuth to GET # /metrics/webinars/{webinarId}/participants

Do I just take each user\_id and make a get-user call to get their email address?

For extra credit - is there a way for me to pass in custom data at the time of joining by adding a url-arg with a `person_id=key` in the link to Zoom, which then becomes available in the user record?

Hey @fluxent, thanks for posting and using Zoom!

To get the email and other data call the [Webinar Participant Report endpoint](https://marketplace.zoom.us/docs/api-reference/zoom-api/reports/reportmeetingparticipants).

As for passing in custom data, you could implement [Webinar Registration](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantcreate) in your code which allows you to add custom data fields.
