# Manejo de Errores

Existen muchas situaciones en las que necesitas notificar un error a un cliente que está usando tu API.

Este cliente podría ser un navegador con un frontend, un código de otra persona, un dispositivo IoT, etc.

Podrías necesitar decirle al cliente que:

* El cliente no tiene suficientes privilegios para esa operación.
* El cliente no tiene acceso a ese recurso.
* El ítem al que el cliente intentaba acceder no existe.
* etc.
