A Webhook Tester gives you a temporary public URL that captures any HTTP request sent to it. Instead of writing a server to handle test events, just paste the URL into your webhook settings and inspect what arrives — headers, body, query strings, and all.
The URL is tied to your browser session. It remains active as long as your browser tab is open. Closing or refreshing the tab and clicking "New" will generate a fresh URL and clear all captured requests.
All standard methods are captured: GET, POST, PUT, PATCH, DELETE, OPTIONS, and HEAD. The method is displayed on each request card so you can see at a glance what was sent.
Requests are stored temporarily in a PHP session on the server and are tied to your browser session cookie. They are not persisted to a database and are discarded when the session expires (typically after 24 minutes of inactivity).
Yes. Copy the generated URL and paste it into the webhook settings of Stripe, GitHub, Shopify, Twilio, or any service that supports configurable HTTP callbacks. Trigger an event and the payload will appear here instantly.
The tool captures up to the PHP server's post_max_size limit (typically 8MB by default). For most webhook payloads — which are usually small JSON objects — this is more than sufficient.
Yes. Any headers sent with the request — including Authorization, X-Signature, or custom headers — are captured and displayed in the Headers tab. This lets you verify that your signing secrets are being transmitted correctly.
Up to 50 requests are stored per session. Once that limit is reached, the oldest request is automatically removed to make room for new ones. The count displayed updates in real time.
You can use the API Request Builder tool (linked in Related Tools) or your terminal with cURL: curl -X POST -H "Content-Type: application/json" -d '{"test":true}' YOUR_URL
A webhook tester is a developer tool that generates a temporary public URL — called an endpoint — which captures any HTTP request sent to it. Rather than writing and deploying a server-side handler every time you want to inspect an incoming webhook, you paste the generated URL into your webhook configuration, trigger an event, and immediately see the full request payload in your browser: headers, body, query parameters, IP address, method, and timestamp.
This makes webhook testers indispensable when integrating third-party services such as Stripe (for payment events), GitHub (for push and PR hooks), Shopify (for order events), Twilio (for SMS callbacks), and countless others. Instead of deploying a staging server just to capture a single test event, you use a webhook tester to validate the exact shape of the payload before writing a single line of handler code.
Webhooks are asynchronous — your server doesn't ask for data, the third-party service pushes it to you when something happens. This makes them harder to debug than regular API calls. If your endpoint returns a 500 error, the third-party retries automatically, but you often can't see what data it sent without logging infrastructure in place.
A webhook tester short-circuits that friction. You can:
X-Stripe-Signature or X-Hub-Signature-256 are present and correctly formatted.When you register a webhook URL with a service, that service stores it and fires an HTTP request to it whenever a relevant event occurs. For example, adding a Stripe webhook for payment_intent.succeeded means Stripe will POST a JSON payload to your URL every time a payment succeeds. Your server receives the request, validates a cryptographic signature (if provided), and processes the event.
The request typically contains:
A webhook tester captures all of these components and presents them in a readable interface so you can understand exactly what your handler will receive.
Once you have a webhook URL from this tool, you can send test requests immediately from your terminal without configuring any third-party service:
# Send a JSON POST
curl -X POST \
-H "Content-Type: application/json" \
-H "X-Custom-Header: myvalue" \
-d '{"event":"order.created","id":12345}' \
YOUR_WEBHOOK_URL
# Send form data
curl -X POST \
-F "name=John" \
-F "status=active" \
YOUR_WEBHOOK_URL
# Simulate a GET with query parameters
curl "YOUR_WEBHOOK_URL?action=ping&source=test"Each of these requests will appear in the tester within seconds, with all headers, body content, and metadata fully visible.
This tool's inspector is split into four tabs for clarity:
Signature verification failures: Stripe, GitHub, and others sign payloads with a secret key and include the signature in a header. If your server rejects the signature, use the Headers tab to confirm the header is present and inspect its format before debugging your HMAC verification code.
Unexpected content types: Some services send application/x-www-form-urlencoded instead of application/json. Seeing the Content-Type header in the inspector tells you exactly how to parse the body in your handler.
Missing fields: If your handler throws a null reference error, the Body tab lets you confirm which fields are actually present in the payload versus which ones you assumed would be there.
Retry storms: When a service retries a failed delivery, you'll see duplicate requests arrive. The timestamp on each captured request helps you correlate retries with your server logs.
Because this is a debugging tool, treat the generated URL as temporary and disposable. Do not use it in production environments or send it to external parties. Webhook payloads often contain sensitive information — order data, user PII, or API keys — so only use a webhook tester with test-mode or sandbox events from your third-party service, never with live production data.
Requests captured by this tool are stored in a server-side PHP session tied to your browser and are not persisted beyond the session lifetime. They are never shared with other users or stored in a database.
Tools like ngrok tunnel localhost traffic to a public URL, letting you receive webhooks directly in a locally running server. A browser-based webhook tester like this one is a simpler alternative when you just need to see the payload — no local server required, no software to install, no tunneling configuration. For active development where you need to run real handler code locally, ngrok is the right choice. For quickly inspecting a payload shape or debugging a misconfigured integration, a browser tester is faster and requires zero setup.
