What is the difference between an API and a webhook?

An API is a request-response model: your app asks for data and gets a response. A webhook is an event-driven model: the external system pushes data to your app when something happens. APIs are like making a phone call; webhooks are like receiving a text notification.

How do webhooks work with WhatsApp Business API?

When a customer sends a WhatsApp message, Meta servers send an HTTP POST request (webhook) to your configured endpoint with the message data. Your server processes the message, generates a response through the AI, and sends it back via the WhatsApp API. This happens in milliseconds.

Webhooks include security mechanisms like signature verification (Meta signs each webhook payload), SSL/TLS encryption for data in transit, and token validation. The receiving server verifies the webhook signature to ensure it genuinely came from the expected source and was not tampered with.

Que es Webhook?

Definition

Webhook

Un webhook es un mecanismo de comunicacion HTTP que permite a una aplicacion enviar datos automaticamente a otra aplicacion en tiempo real cuando ocurre un evento especifico, sin necesidad de que la aplicacion receptora consulte continuamente por actualizaciones.

Understanding Webhook

Los webhooks funcionan como notificaciones push entre servidores. En lugar de que tu sistema pregunte repetidamente "hay algo nuevo?", el sistema externo te avisa automaticamente cuando ocurre algo relevante. En el ecosistema de WhatsApp, Meta envia webhooks a tu servidor cada vez que un cliente envia un mensaje, permitiendo respuestas en tiempo real. Tecca recibe webhooks principalmente de Meta Cloud API para mensajes de WhatsApp, permitiendo que el asistente reaccione instantaneamente a cualquier mensaje entrante.
