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
