Create a unique webhook endpoint URL
Configure your service to send webhooks to this URL
See all incoming requests with headers and body
Send a webhook to your URL above to see it here
A webhook is an HTTP callback that sends real-time data from one application to another when a specific event occurs. Instead of constantly polling an API for updates, webhooks push data to your application immediately when something happens, making them more efficient than traditional polling.
Webhooks are commonly used for notifications, integrations, and automation. For example, when a payment is completed, a payment processor sends a webhook to your server with transaction details. When testing webhook integrations, you need a publicly accessible URL to receive these HTTP requests.
{
"action": "opened",
"pull_request": {
"id": 1,
"title": "Add new feature",
"user": {
"login": "developer"
}
},
"repository": {
"name": "my-repo",
"full_name": "user/my-repo"
}
}
Click "Generate Webhook URL" to create a unique endpoint. This URL is where you'll send your webhook requests for testing. The URL remains active for your testing session.
Copy the generated URL and paste it into your webhook configuration in the service you're integrating (GitHub, Stripe, Slack, etc.). Most services have a "Webhooks" or "Integrations" section in their settings.
Perform actions in your service that trigger webhooks (create a pull request, make a payment, send a message). The webhook tester will capture and display all incoming requests in real-time.
View the complete request details including HTTP method, headers, and body. This helps you understand the webhook payload structure and debug integration issues.
When building webhook integrations, use this tester to see exactly what data your application will receive. Inspect the payload structure before writing code to handle it.
If webhooks aren't working in your application, use this tester to verify that the service is sending webhooks correctly. Check if the payload format matches your expectations.
During development, you may not have a publicly accessible server. Use this tester as a temporary endpoint to receive and inspect webhooks without setting up ngrok or similar tools.
Capture real webhook payloads to document the data structure for your team. This is especially useful when the service's documentation is incomplete or outdated.
Verify that third-party services are sending webhooks as expected. Check timing, payload format, and headers before integrating into your production application.
