What is Webhook?

A webhook is a way for one system to automatically notify another system when something happens. In messaging, webhooks let platforms like Instagram or WhatsApp instantly alert your business tools when new messages arrive, instead of constantly checking for updates. Think of it as a doorbell—it rings when someone's there, rather than making you peek outside every few seconds.

Why Webhook Matters

Real-time notifications when messages arrive
More efficient than constantly polling for updates
Enables instant automation and integrations
Foundation for building custom messaging workflows
