Parámetros de cabecera

Idempotency-Key?string

Clave única generada por el cliente para garantizar la idempotencia en los reintentos. Te permite reenviar de forma segura la misma petición: la primera respuesta se cachea y se devuelve sin volver a ejecutar la mutación. Es una cadena opaca para el servidor; cualquier valor único de hasta 64 caracteres es válido (UUID v7, UUID v4, ULID, nanoid, etc.). Se recomienda UUID v7 por coherencia con los identificadores de la API. La misma clave reutilizada con un body distinto devuelve 409 idempotency_key_reused.

Longitud1 <= length <= 64
