Cancels a created or active version of a subsidy application, when the customer revokes the authorization (Vollmacht). The time of the request is the date of the revocation. The subsidy application status will become canceled, which is final. To start the authorization again, send a new application with POST /accounts/{account_id}/subsidy_applications.

A 422 error is returned when the version is superseded. Canceling a version that is already canceled does nothing: it returns the subsidy application unchanged.

An event with type subsidy_application.canceled will be created, except when the version was already canceled.
