What is Webhook?

Definition

Webhook

A webhook is an HTTP communication mechanism that allows one application to automatically send data to another application in real time when a specific event occurs, without the receiving application needing to continuously check for updates.

Understanding Webhook

Webhooks function as push notifications between servers. Instead of your system repeatedly asking "is there anything new?", the external system notifies you automatically when something relevant happens. In the WhatsApp ecosystem, Meta sends webhooks to your server every time a customer sends a message, enabling real-time responses. Tecca primarily receives webhooks from Meta Cloud API for WhatsApp messages, letting the assistant react instantly to any incoming message.

FAQ: Webhook

Common questions about 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.
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.
