Webhook when a participant authenticates

There are two webhooks related to user authenticated and user presence:

  1. https://marketplace.zoom.us/docs/api-reference/webhook-reference/user-events/user-signed-in
  2. https://marketplace.zoom.us/docs/api-reference/webhook-reference/user-events/presence-status-updated

These may/may not be exactly what you are seeking, but just making note of them here.

You can subscribe to the (meeting|webinar).participant_joined events for meetings and webinars. Using these events, you can identify if a user is an authenticated Zoom user by using the EventObject->payload->{relativeMeetingObject}->participant->id property and the user_name property.

You can correlate current meeting participants to Zoom users with the id property in (meeting|webinar).participant_joined event.
