# Cancel a Meeting

> Cancel a meeting and run all cancellation side effects. Works on any meeting belonging to your client.

When cancelled, Nexor:

* Cancels the lead's and host's pending reminders.
* Notifies the host and sends the lead a cancellation email.
* Deletes the external calendar event and frees the availability slot.
* Logs a `meeting_cancelled` timeline activity.
* Fires a `meeting.cancelled` outbound webhook and, when configured, triggers the re-engage agent.

Meetings owned by an external provider that Nexor doesn't control (e.g. an inbound-only Calendly invitee) are **not** cancelled; the response returns `"skipped": true`.

**Idempotency:** cancelling a meeting that is already `cancelled` is a safe no-op (`"idempotent": true`).
