Quick Answer
A free webhook tester gives you a unique HTTPS URL that captures any HTTP request (headers, body, query params) in real time. Requex.me generates one instantly with no signup. Paste the URL into Stripe, GitHub, Shopify, or any provider and inspect the exact payload they send.
The Best Free Webhook Tester for Real-Time Debugging
Requex.me is an advanced, free webhook tester that allows developers to generate unique HTTPS endpoints, capture real-time HTTP requests, and simulate custom responses without any registration. Generate a unique webhook URL instantly and start capturing HTTP requests in real-time. Completely free, no signup required, no limits.
What exactly is a free webhook tester?
A free webhook tester is an online tool that generates a unique, public URL where you can send HTTP requests. Every request sent to this URL is captured and displayed in real-time, allowing you to inspect headers, query parameters, request bodies (JSON, XML, form data), and HTTP methods.
Webhook testers are essential for developers working with event-driven integrations. Whether you're building a Stripe payment handler, a GitHub CI/CD webhook, a Shopify order notification, or a Discord bot, a webhook tester lets you see exactly what data the external service sends before you write your handler code.
Requex.me is a completely free webhook tester with no hidden fees, no usage limits, and no account required. Just visit the homepage and your unique webhook URL is ready to use.
Key Features
Incoming requests arrive via WebSocket: no page refresh, no polling delay. Click any captured request to see full headers, body, query parameters, and HTTP method. The JSON viewer is syntax-highlighted with collapsible nodes so nested payloads (like Stripe's data.object) are navigable rather than a wall of text.
Custom response simulation is built in and free on every endpoint. Open Response Settings and set any HTTP status code, write a response body, add headers, or insert a delay. The dark mode is system-aware and works across the entire interface.
Every endpoint URL is HTTPS and uniquely generated per session. All HTTP methods are captured: POST, GET, PUT, PATCH, DELETE, HEAD, and OPTIONS.

Send Your First Test in 30 Seconds
No UI needed. Copy your webhook URL from the dashboard, then fire a test event straight from the terminal:
curl -X POST https://requex.me/hook/YOUR-WEBHOOK-ID \
-H "Content-Type: application/json" \
-d '{"event":"order.created","id":42,"amount":99.00}'The request appears in your dashboard within a second. All HTTP methods are captured: swap -X POST for GET, PUT, PATCH, or DELETE — they all work.
Test a response code (simulate a 422 for idempotency testing):
# First enable Response Settings in the dashboard, set status to 422
# Then trigger the event — the provider sees 422 and logs it
curl -X POST https://requex.me/hook/YOUR-WEBHOOK-ID \
-H "Content-Type: application/json" \
-d '{"type":"payment_intent.succeeded"}'Supported Integrations
Our free webhook tester works with any service that sends HTTP requests, including:

What Makes a Good Webhook Test?
A thorough webhook test checks more than whether the payload arrived. It verifies the full round-trip: the provider sent the correct payload structure, your endpoint responded within the timeout window, and the response code triggered the expected provider behaviour (retry, success, or failure).
Payload structure test
Confirm the provider sends the exact fields your handler expects. Capture a live event and compare it field-by-field against the documentation. Providers often include undocumented fields or change structures between API versions.
Response code test
Configure your webhook endpoint to return 200, 500, or 422 and observe what the provider does next. Stripe retries on 5xx. Shopify disables the subscription after 8 consecutive failures. Knowing this prevents silent data loss in production.
Timeout test
Add a 6-second delay and send a Shopify webhook. Shopify's 5-second timeout means it registers as a failure. Add a 35-second delay for Stripe to verify their 30-second cutoff. These tests are not possible without response delay simulation.
Idempotency test
Replay the same captured payload to your local handler three times. Your logic should produce the same outcome on every replay: no duplicate records, no double-sent emails. This is the test most developers skip and regret in production.

Frequently Asked Questions
Is the webhook tester really free?
Yes, completely. There is no hidden paid tier for core features. You get a unique URL, real-time request capture, JSON inspection, and custom response simulation all without creating an account or entering a credit card.
How do I get a free webhook URL?
Open requex.me in any browser. A unique webhook URL is generated automatically. No form to fill out, no email to confirm. Copy it and paste it wherever you need a webhook endpoint.
Can I test Stripe, GitHub, or Shopify webhooks with this tool?
Yes. Paste your Requex URL into the webhook settings of any provider and trigger a test event. The full request: headers, payload, and HTTP method — appears in your dashboard within a second. We have dedicated guides for Stripe, GitHub, and Shopify.
Can I customize what response my webhook endpoint returns?
Yes — and it is free. Click Response Settings in the dashboard to set any HTTP status code (200, 400, 422, 500), write a custom response body, add headers, or insert a delay. This is useful for testing retry logic and error handling without deploying any code. See the webhook simulator page for more detail.
What is the difference between this and webhook.site?
On webhook.site, custom responses require a paid Pro plan. On Requex.me they're free on every endpoint. Requex.me also uses WebSocket so requests appear the moment they arrive, no polling delay. Full comparison: webhook.site alternative.
Can I test webhooks on localhost?
Requex.me is the capture side. It receives the webhook from your provider and shows you the payload. You can then copy the payload and replay it to your local server with cURL. For a full walkthrough, see the local webhook testing guide.
How long are webhook requests stored?
Requests are stored for your active session. For longer-term storage or to keep a history across sessions, create a free account and your webhooks and request history will be tied to your profile. Do not rely on anonymous endpoints for data you need to keep permanently.
Does it support GET, PUT, PATCH, and DELETE: not just POST?
Yes — all HTTP methods are captured. POST, GET, PUT, PATCH, DELETE, HEAD, and OPTIONS requests all appear in your dashboard with full headers, body, and query parameters. Useful for testing REST-style callback URLs that use methods other than POST.
How do I test webhook signature verification?
Capture a real event from your provider using Requex.me, then copy the exact headers — including the signature header like Stripe-Signature or X-Hub-Signature-256 — along with the raw body. Replay this to your local handler with cURL to test your signature verification logic against a genuine signed payload. See the webhook security guide for full examples.
