An automated HTTP callback Meta sends so your system receives WhatsApp messages and status updates in real time.
A webhook is a mechanism where Meta pushes data to your application the moment an event happens, rather than your application repeatedly asking for updates. For the WhatsApp Business Platform, webhooks deliver inbound customer messages, message status changes (sent, delivered, read, failed), template status updates, and account events.
You register a public endpoint with Meta, verify it, and subscribe to the events you care about. From then on, every relevant event is posted to that URL as JSON, letting your platform react instantly — for example triggering a chatbot reply or updating a CRM.
Webhooks are the backbone of real-time two-way messaging; without them, a business could send but never reliably receive or track messages.
Webhooks are what make real-time replies, read receipts, and automations possible — they connect WhatsApp events to your tools instantly.
Defuser AI manages all webhook plumbing for you, so inbound messages and statuses flow straight into automations and the inbox on your WhatsApp Business API.
