What are Webhooks?

Webhooks are automated messages sent from apps when something happens. They're like "event listeners" that notify your application when specific events occur on external services (like payment processing, form submissions, or code deployments).

Instead of constantly polling for changes, webhooks push data to your application in real-time, making them more efficient and responsive.

Common Webhook Use Cases

💳 Payment Processing

Stripe, PayPal send payment confirmation webhooks

📦 Shipping Updates

Shipment tracking webhooks notify your app of status changes

💬 Chat Notifications

Slack, Discord webhooks for sending messages

📝 Form Submissions

Receive notifications when forms are submitted

🔄 Deployment Notifications

GitHub, GitLab webhooks for CI/CD pipelines

📊 Analytics Events

Track user actions and send to analytics services

How to Test Webhooks

  1. Create a webhook endpoint using this tool
  2. Copy the provided URL
  3. Configure it in your service (GitHub, Stripe, etc.)
  4. Trigger the event that fires the webhook
  5. View the request details in real-time
  6. Debug headers, body, and parameters
  7. Download the request for further analysis

HTTP Methods Explained

Retrieve data from a resource without modifying it

POST

PATCH

Partially update a resource with new data

DELETE

Security Best Practices

  • Always validate webhook signatures to ensure authenticity
  • Use HTTPS/TLS encryption for all webhook URLs
  • Implement rate limiting to prevent abuse
  • Log all webhook requests for audit purposes
  • Store sensitive data (API keys, tokens) securely
  • Set up retry logic with exponential backoff
  • Implement idempotency to handle duplicate webhooks

FAQ

How long do webhook endpoints persist?

This tool creates temporary endpoints. For production, set up a dedicated server to receive webhooks.

Can I test webhooks locally?

Yes, use ngrok to expose your local server to the internet, then use the ngrok URL as your webhook endpoint.

How do I handle webhook failures?

Implement retry logic with exponential backoff. Log failures and set up monitoring alerts.
