# Cancel a Scheduled Event

> Cancel a scheduled Zeeg event by UUID. Notifies all invitees and hosts and marks the event as cancelled in the system.



## OpenAPI

````yaml PUT /scheduled-events/{uuid}/cancel
openapi: 3.0.0
info:
  title: Zeeg Public API
  description: >-
    Zeeg public API documentation.


    ## Authentication

    All endpoints require a Bearer token. You can generate an API token from
    [your Zeeg dashboard](https://app.zeeg.me/account/settings/api-access).


    Each token is scoped to specific permissions (e.g. `events:read`,
    `webhooks:write`). Make sure your token has the required scopes for the
    endpoints you want to use.


    ## Recommended Headers

    We recommend including the `Accept: application/json` header in all API
    requests to ensure you receive JSON responses.
