# Cancel

#### Description
Cancels a Scheduling Request using a Cronofy Account.

Authentication is with either:

- an access token for the Organizational Unit, created by authorizing an application for an [Organizational Unit scope](/developers/authorization/organization-connect/index.md) like `organizational_unit_scheduler`

- the `client_secret` of an [Internal Application](/developers/application-management/internal-applications/index.md) linked to the Organizational Unit.

The API also supports the `sub` of an Account connected to the Organizational Unit in the  `Cronofy-Impersonate` header.
