What is a Webhook?
A Webhook is a mechanism where one system automatically sends a message (HTTP request) to another system as soon as a defined event occurs. For example: a customer fills out a form on a website → the Webhook sends the data to N8N → N8N saves it in the CRM and sends a WhatsApp message. Everything happens automatically and in real time. Webhooks are the foundation of modern business automation: they connect different systems and enable an immediate response to any event.
How Does a Webhook Work?
- An event occurs — a new lead, order, payment, or WhatsApp message
- The source system sends an HTTP POST request — containing all the relevant data
- The destination system receives and processes it — saves it to the CRM, sends a message, or triggers a workflow
Practical Example: Contact form on a website → Webhook sends to N8N → N8N saves in Zoho CRM + sends a WhatsApp message to the customer + alerts a sales representative. Everything happens within 3 seconds.
Examples of Webhooks in Business Automation
| Event | Webhook Sends To | Result |
|---|---|---|
| New lead in form | N8N → Zoho CRM | Lead saved + WhatsApp response |
| New order in Shopify | N8N → Shipping system | Automatic shipment generation |
| Credit card payment | N8N → Invoicing system | Automatic invoice |
| Incoming WhatsApp message | WhatsApp API → N8N | AI agent responds |
Webhooks in a Business Context
Webhooks are the "glue" that connects business systems. Without them, you would have to check each system manually or write complex scripts. With them — everything happens in real time, automatically.
At Automaziot AI we use Webhooks as a core component in every automation project — connecting N8N to forms, WhatsApp Business API, Zoho CRM, and any business system.
