How to Test Auth0 Webhooks
Auth0 can stream tenant log events in near real time, making it easy to react to signups, logins, and password lifecycle events.

Follow these steps to start receiving Auth0 webhooks for testing:
- Go to HookRay and click "Start Testing — Free" to get your unique webhook URL.
- Copy the URL (e.g.,
https://h.hookray.com/abc123). - In your Auth0 dashboard, navigate to the webhook settings and paste the HookRay URL as your endpoint.
- Select the events you want to receive (see list above).
- Trigger a test event — HookRay will show the incoming webhook in real-time.
3. Sample Auth0 Webhook Payload
Here's an example of what a Auth0 webhook payload looks like:
{
"date": "2026-03-20T09:15:30.000Z",
"type": "s",
"description": "Success Login",
"client_name": "RapidAPI Demo App",
"user_id": "auth0|abc123xyz",
"user_name": "seller@example.com",
"ip": "203.0.113.42"
}4. Frequently Asked Questions
How do I test Auth0 webhooks without deploying?
Use HookRay to get an instant public webhook URL. Paste it into your Auth0 dashboard's webhook configuration, trigger an event, and watch the payload arrive in real time. No code, no ngrok, no deployment required. The free tier captures 100 requests per month and works on all Auth0 event types.
Why aren't my Auth0 webhooks arriving?
The four most common causes: (1) the endpoint URL isn't publicly accessible — Auth0 can't reach localhost; (2) the wrong events are subscribed in your Auth0 dashboard; (3) signature verification is rejecting the request before your handler runs; (4) Auth0 can't reach your server because of a firewall, expired SSL certificate, or wrong DNS. Use HookRay's URL to isolate which of these four is failing — if HookRay receives the webhook, the problem is in your handler. If HookRay doesn't, the problem is in Auth0 configuration.
Why am I getting 400 or 500 errors from my Auth0 webhook?
Auth0 reports the response status your endpoint returned. HookRay accepts any payload and returns 200 OK by default, so if you see 400/500 in your Auth0 dashboard while pointing at HookRay, the issue is in Auth0's configuration (wrong event, malformed signing secret, etc.). If you point at your own endpoint and get 400/500, the issue is in your handler — capture the request with HookRay, replay it locally, and debug from the captured payload.
How do I verify Auth0 webhook signatures?
Auth0 signs each webhook request with a shared secret. Capture the raw headers and body using HookRay, then verify the signature in your application using Auth0's SDK or a standard HMAC library. Once verification works against HookRay-captured data, you can safely deploy. Auth0's docs (linked above) cover the exact signing algorithm.
Can I replay a captured Auth0 webhook?
Yes — HookRay's replay feature re-sends any captured webhook to a different endpoint with one click. This is the fastest way to fix a buggy handler: capture the payload once, fix your code, and replay until it works. No need to re-trigger the event in Auth0.
5. Next Steps
- Use HookRay's webhook replay feature to re-send captured webhooks while building your handler
- Enable smart parsing (Pro plan) to see Auth0-specific fields highlighted automatically
