1. How Webhooks Work
You provide a URL (endpoint) to the service you want to receive updates from. When an event occurs (new order, form submission, etc.), the service sends an HTTP POST request to your URL with event data.
2. Setting Up a Webhook Endpoint
Your endpoint must: accept POST requests, respond with 200 OK quickly, and process the payload appropriately. Automation platforms like Make and Zapier provide webhook URLs automatically.
3. Security Considerations
Verify webhook signatures when provided. Use HTTPS only. Implement rate limiting. Don't trust the payload blindly—validate and sanitize data before using it.
Wrap-up
Webhooks enable real-time automations without the overhead of polling. Most SaaS apps support webhooks—check their API documentation to get started.
