Webhook
An HTTP callback that sends real-time data when events occur. Instead of polling for changes, systems push notifications to your endpoint automatically.
In-Depth Explanation
A webhook is an HTTP-based callback mechanism. When an event occurs in one system, it automatically sends data to a URL you specify - enabling real-time integration without polling.
How webhooks work:
- You register a URL endpoint with a service
- Event occurs in the service
- Service sends HTTP POST to your URL
- Your endpoint receives and processes the data
- You return acknowledgment (2xx status)
Webhook characteristics:
- Push-based: Data comes to you
- Real-time: Immediate notification
- Event-driven: Triggered by specific events
- HTTP-based: Standard web protocols
Common webhook events:
- Payment completed
- Form submitted
- Record created/updated
- Status changed
- File uploaded
- Message received
Business Context
Webhooks enable real-time automation. Instead of checking "did payment complete?" every minute, you're notified instantly when it happens.
