WhatsApp Webhook: What It Is and Why Integrations Need It
What a webhook is, what events it delivers, and why every integration runs on it.
The short answer
A WhatsApp webhook is a real-time feed that Meta uses to push events to your software: incoming messages, message statuses, and template approvals. Instead of your system asking 'anything new?', the webhook tells it the moment something happens. Every shared inbox, bot, and integration is built on webhooks.
How a webhook works
It is a simple push, with security around it.
- You register a public URL with Meta
- Meta sends JSON events to that URL in real time
- Meta verifies your endpoint with a token before sending
- Your system must acknowledge events quickly to avoid retries
Why merchants never see webhooks
Webhooks are plumbing; the inbox is the tap.
- Providers handle webhook setup, retries, and security
- Events become conversations, badges, and automations in the inbox
- You see the result — a message arriving in the shared inbox — not the JSON
- When webhooks break, messages silently stall; that is why reliability matters
How Wutt handles webhooks
Wutt runs the webhook layer for the Meta Cloud API: verified endpoints, retry handling, and real-time delivery into the shared WhatsApp and Telegram inbox. Messages appear as they arrive, and automations trigger off the same events.

Common questions
If you build your own integration, yes. With a provider like Wutt, it is handled for you.
Meta retries failed deliveries for a period. Persistent failures cause missed messages — a provider monitors and recovers them.
Meta signs webhook requests, and endpoints verify tokens before accepting events. See the security page for details.
They deliver the events; automations, chatbots, and CRMs decide what to do with them.
