How to Use Webhook Tester

Testing webhooks usually means deploying an endpoint or using a third-party service. The Webhook Tester gives you a unique URL to receive webhook calls so you can send requests from another app and view headers and body in real time—ideal for debugging payment gateways, CI hooks, or any service that sends HTTP callbacks.

What does the webhook tester do?

It gives you a unique URL to receive webhook calls. You send requests to that URL from another app and view headers and body here in real time. Typically you see method, URL, headers, and body (raw and optionally parsed); timestamp and IP may be shown. Incoming requests may be stored temporarily to display them—check the tool's policy; do not send sensitive production data. Use it to debug payment gateways, CI hooks, or any service that sends HTTP callbacks, and to verify payload and headers without deploying your own endpoint. If your webhook is not appearing, confirm the request reaches the URL (check firewall and HTTPS); some senders retry with backoff; ensure the tester URL is correct and the service can reach the public internet.

Key Features

• Unique URL — You get a URL to receive webhook calls. Send requests to it from another app and view them here.
• Flow — Get a unique URL, send webhooks to it, and view all incoming requests in real-time.
• Details shown — Typically method, URL, headers, and body (raw and optionally parsed). Timestamp and IP may be shown.
• Storage — Incoming requests may be stored temporarily to display them. Check the tool's policy; do not send sensitive production data.
• No account — Use as often as you need without sign-up.
• Troubleshooting — Confirm request reaches the URL (firewall, HTTPS). Senders may retry with backoff. Ensure tester URL is correct and service can reach the public internet.

How to Use the Webhook Tester

1. Open the Webhook Tester tool.
2. Copy the unique URL. Configure your app or service to send webhooks to that URL.
3. Trigger a webhook (e.g. payment, CI). View method, headers, and body in the tool. Use the "Use tool" button on the docs page if you are reading this from the documentation.

Real Use Cases

• Payment gateways — Point Stripe, PayPal, or other payment webhooks to your tester URL. Inspect payload and headers. Verify with JSON Formatter if body is JSON. Use with JWT Decoder if auth uses JWT.
• CI/CD — GitHub, GitLab, or Jenkins webhooks. See payload and headers without deploying an endpoint. Use with Base64 Encoder if payload is encoded.
• Third-party APIs — Any service that sends HTTP callbacks. Debug without exposing your own server. Use with JSON Formatter to parse body.
• Documentation — Show team or clients how webhooks are received. Use live requests as examples.
• Support — Reproduce issues by having user send webhook to your tester URL. Inspect what their service sends (redact sensitive data).
• Learning — Understand webhook format: method, headers, body. See retries and status codes.

Why Use the Webhook Tester Instead of Alternatives?

• vs. JSON Formatter — JSON Formatter formats JSON. This tool receives HTTP requests and shows full request. Use formatter to parse body after receiving.
• vs. JWT Decoder — JWT Decoder decodes JWTs. This tool receives webhooks. Use decoder if webhook auth or payload contains JWT.
• vs. Base64 Encoder — Base64 Encoder encodes/decodes base64. This tool receives and displays webhooks. Use encoder if body is base64.
• vs. Own endpoint — No deployment. Get a URL instantly. Use for quick debugging; use your own endpoint for production.

Benefits for Developers and DevOps

• Developers — Debug webhooks without deploying. See exact payload and headers.
• DevOps — Verify integrations. Test retries and failure cases with real URLs.

Common Mistakes

• Webhook not appearing — Confirm the request reaches the URL (check firewall and HTTPS). Some senders retry with backoff. Ensure the tester URL is correct and the service can reach the public internet.
• Sending production data — Incoming requests may be stored temporarily. Do not send sensitive production data; check the tool's policy.
• Wrong URL — Copy the exact URL. Missing path or typo will result in no request shown.
• Expecting persistence — Requests may be temporary. Copy or export if you need to keep them.

Frequently Asked Questions

What does the webhook tester do?

It gives you a unique URL to receive webhook calls. You send requests to that URL from another app and view headers and body here in real time.

How does it work?

Get a unique URL, send webhooks to it, and view all incoming requests in real-time.

What request details are shown?

Typically method, URL, headers, and body (raw and optionally parsed). Timestamp and IP may be shown.

Is my webhook data stored?

Incoming requests may be stored temporarily to display them. Check the tool's policy; do not send sensitive production data.

When should I use the webhook tester?

Why is my webhook not appearing?

Confirm the request reaches the URL (check firewall and HTTPS). Some senders retry with backoff. Ensure the tester URL is correct and the service can reach the public internet.

Conclusion and Try the Tool

Webhook Tester gives you a receive URL and live view in one place: get URL, send webhooks, inspect. No account. For JSON body use JSON Formatter, for JWT use JWT Decoder, and for base64 use Base64 Encoder.
