# Validación Fallida

Este evento del webhook se dispara cuando el firmante alcanza el máximo permitido de intentos (3 intentos) para validar su identidad utilizando los métodos de autenticación disponibles en ZapSign: Reconocimiento Facial y Validación de Identidad.

Cuando se recibe esta notificación, significa que el firmante no puede continuar con el proceso de firma electrónica hasta que el cliente tome una acción.

### Acciones posibles que puede realizar el cliente:

* Cambiar el método de autenticación: Utilizar el endpoint [Actualizar firmante](/espanol/firmantes/atualizar-signatario.md) para cambiar el método de autenticación por uno alternativo (por ejemplo, OTP por SMS o email).
* [Reiniciar intentos de validación: ](/espanol/firmantes/reset-signer-attempts.md)Con éste endpoint el firmante tendrá tres nuevos intentos para realizar la validación.

Este evento permite que el cliente tome decisiones oportunas y rápidas para asegurar la continuidad y la seguridad del proceso de firma electrónica. 

{% hint style="warning" %}
En la respuesta el parámetro `authentication_failure_reason` explica la razón de falla de la validación
{% endhint %}
