# Tareas en Segundo Plano { #background-tasks }

Puedes definir tareas en segundo plano para que se ejecuten *después* de devolver un response.

Esto es útil para operaciones que necesitan ocurrir después de un request, pero para las que el cliente realmente no necesita esperar a que la operación termine antes de recibir el response.

Esto incluye, por ejemplo:

* Notificaciones por email enviadas después de realizar una acción:
