# Waiting Participant Left

> The waiting participant left webhook event

A waiting participant left event is sent when a knocking participant (see [blog post](https://www.daily.co/blog/manage-call-permissions-with-dailys-knocking-feature/)) leaves the knocking state. In other words, when a knocker begins to knock and leaves before being allowed into a room, a `waiting-participant.left` event is sent. If a knocker is allowed into a room and then leaves, a [`participant.left`](./participant-left) event is sent.
