# Cancelar una sesión de clase

POST https://app.recurrente.com/api/class_sessions/{class_session_id}/cancellation

El negocio cancela una sesión ("hoy no hay yoga"): deja de recibir
lugares, la hora del instructor y del salón queda libre, y cada lugar se
cancela como el negocio y se devuelve lo que pagó (una sesión de paquete
vuelve al paquete). Cada cliente recibe el aviso de cancelación. Si algún
reembolso falla responde `422` con `code: seats_left` y `booking_ids`;
volver a llamar termina esos lugares sin devolver ninguno dos veces.
Requiere que la llave pueda mover dinero.


Reference: https://docs.recurrente.com/referencia-api/api-reference/bookings/cancel-class-session

## Authentication

- `X-SECRET-KEY` header (required) — Tu clave secreta de API. Una llave de cuenta (`sk_live_...`, `sk_test_...`) opera sobre su propia cuenta y, con `X-ACCOUNT-ID`, sobre sus cuentas conectadas. La llave también fija el ambiente: una `sk_test_` solo lista y resuelve objetos de prueba (`live_mode: false`) y una `sk_live_` solo objetos reales. Un ID del otro ambiente responde `404` (`401` en `/customers`). Una llave de organización (`sk_org_live_...`, `sk_org_test_...`) alcanza todas las cuentas de una organización y solo sirve para leer: saldos, movimientos y reportes. Para operar sobre una cuenta debe nombrarla con `X-ACCOUNT-ID`; omitirlo en una lectura devuelve todas las cuentas de la organización. Cualquier otro endpoint responde `403` con `code: organization_key_unsupported`.
