What Is a Webhook?

A webhook is an automatic message one system sends to another the moment something happens — for example, notifying your site immediately when a payment is received.

It matters because it replaces slow, repeated "has anything changed?" checking with instant, event-driven updates. That makes integrations faster, lighter and more responsive.

An Everyday Analogy

A webhook is like a doorbell. Instead of you repeatedly opening the door to check if anyone has arrived, the bell rings the instant a visitor turns up. The event tells you, not the other way around.

  • Triggered by a specific event.
  • Sends data automatically, in real time.
  • Avoids constant, wasteful polling.
  • Powers many integrations between tools.

Why It Matters to You

Webhooks make connected systems feel instant and efficient.

  • Real-time updates between your tools.
  • Less load and lower cost than constant checking.
  • Enables automations like instant order processing.
  • A common, reliable way to connect modern services.
