Webhook Tester

Generate a unique webhook URL to capture and inspect incoming HTTP requests from any service.

How to Use the Webhook Tester

This tool provides you with a unique URL that captures any HTTP requests sent to it. Perfect for testing webhooks from third-party services.

Step-by-Step Instructions:

1. Copy your webhook URL from the box above
2. Configure your webhook in the service you're testing (GitHub, Stripe, Slack, etc.)
3. Trigger the webhook by performing an action in that service
4. View the captured request below - headers, body, and all details
5. Regenerate URL if you want a fresh endpoint
6. Clear History to remove all captured webhooks

Common Use Cases:

• GitHub Webhooks: Test repository events, pull requests, issues, and push notifications
• Stripe Webhooks: Debug payment events, subscription updates, and customer events
• Slack Webhooks: Test slash commands, interactive components, and event subscriptions
• Custom APIs: Verify your webhook payload format before implementing the receiver
• Third-party Integrations: Inspect webhook data from any service that sends HTTP callbacks

Example Webhook Request:

curl -X POST https://internettoolset.com/api-tools/webhook-capture/7e4ef357210e \
  -H "Content-Type: application/json" \
  -d '{"event": "user.created", "user_id": 12345, "email": "user@example.com"}'

Features:

• Captures all HTTP methods: GET, POST, PUT, DELETE, PATCH
• Displays full request headers
• Shows query parameters and request body
• Stores last 10 webhook requests
• Auto-detects content type
• Session-based storage (data clears when session ends)
