What is WhatsApp Webhook?
A WhatsApp webhook is a URL on your server that Meta calls automatically every time something happens on your WhatsApp Business API number โ a customer message arrives, a sent message is delivered or read, or a button is tapped. Instead of your software repeatedly asking "any new messages?", WhatsApp pushes each event to you in real time as a small JSON packet.
Webhooks are what make chatbots and CRM integrations possible. When a customer replies "YES" to a demo offer, the webhook fires, your system reads the reply and can instantly create a lead in your CRM, notify a salesperson, or trigger the next bot response. For an Indian SaaS or agency, one webhook endpoint typically handles incoming messages, delivery receipts and status updates for every customer number connected.
