+### Seated event types
+
+For event types with [seats enabled](/event-types/offer-seats), the `attendees` array in webhook payloads contains only the attendee associated with the specific seat that triggered the webhook. For example, when a new seat is booked, the webhook includes only that seat's attendee — not all attendees across the entire booking. This applies to all booking-related triggers (`BOOKING_CREATED`, `BOOKING_RESCHEDULED`, etc.).
+
 ### Example webhook payloads
 
 Most webhook events use a nested payload format with booking details inside a `payload` object. The `MEETING_STARTED` and `MEETING_ENDED` events use a different flat format where booking fields are at the top level.
