Requires the `X-Customer-Session` header. The enterprise service API key is OPTIONAL (see /customer/tickets). Only cancels PENDING sales (releases inventory and seats). A CONFIRMED sale responds 409 with code `REFUND_REQUIRED`: refunds are handled by the organizer. `{id}` accepts the sale id or its `reference`.

`POST /customer/tickets/{id}/cancel`
