What is Webhook Tester?

Webhook tester to instantly generate a unique temporary URL for testing webhook integrations.

Send any HTTP request to your endpoint and see it appear in real-time with full details: method, headers, body, query parameters, and timestamp. Use it for debugging payment webhooks from Stripe or PayPal, testing CI/CD notifications from GitHub Actions, verifying Slack or Discord bot callbacks, or any API integration that sends HTTP callbacks. Unlike RequestBin (now paid) and webhook.site (with usage limits), ToolBox provides a free webhook testing endpoint with no account required. No signup, no usage caps, no restrictions.

How to Use Webhook Tester

1Click 'Generate URL' to create a unique temporary webhook endpoint that is ready to receive HTTP requests
2Copy the generated URL and paste it into the webhook configuration of the service you are testing (Stripe, GitHub, Slack, etc.)
3Send a test request or trigger the webhook from your integration and watch the request appear in the log in real-time
4Click on any received request to inspect its full details - HTTP method, headers, body payload, and query parameters

Frequently Asked Questions

How long are webhook URLs active?

Webhook URLs are temporary and active for your current browser session. Stored requests may be cleared on serverless cold starts. For persistent testing, keep the tab open during your debugging session.

What HTTP methods are supported?

All standard HTTP methods: GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS. The tool captures and displays the full request regardless of method.

Is this secure?

Webhook URLs are randomly generated UUIDs that are practically impossible to guess. However, as with any webhook testing service, avoid sending sensitive production secrets or real customer data to test endpoints.

Is this a free RequestBin alternative?

Yes. RequestBin moved to a paid model and webhook.site has usage limits on free accounts. ToolBox provides free webhook testing with no account creation, no usage limits, and no restrictions on the number of requests you can receive.

Can I test Stripe webhooks with this?

Yes. Generate a webhook URL, paste it into your Stripe dashboard webhook settings, and trigger a test event. The request will appear in real-time showing the full JSON payload, headers, and signature Stripe sends.

Can I see the full request body?

Yes. The tool displays the complete request including HTTP method, all headers, the raw body (JSON, form data, or plain text), query parameters, and the exact timestamp of when the request arrived.

How many requests can I receive?

There is no hard limit on the number of requests. The tool stores received requests in memory for your current session. If you need to clear old requests, generate a new URL to start fresh.

Do I need to create an account?

No. Click the generate button and you get a working webhook URL instantly. No signup, no email verification, no credit card. Just generate and start testing.
