Hooklistener is now fully focused on the webhook debugger. Spin up a listener, watch payloads stream in live, replay to any environment, and annotate incidents without adding a single line of code.

Every team follows the same flow—capture the webhook, inspect the payload, replay the request—whether they're shipping features or triaging outages.
Prefer a different workflow? Anything that sends HTTP can point at the debugger.
See how the debugger worksCapture, inspect, replay, and document every webhook in a single surface that everyone can open—no custom tooling or new SDKs required.

Create a Hooklistener URL, point your vendor at it, and the debugger starts storing every request with headers, payload, and metadata.

Search payloads, validate signatures, annotate failures, and share the live link so anyone on the team can see the same request.

Send the payload to prod, staging, or localhost, diff responses, and convert fixes into reusable automations when you’re ready.

Before: direct webhooks, zero context when something failed. After: Hooklistener sits in front, the debugger keeps every payload, and replaying failures is a single click.

app.post('/stripe-webhook', async (req, res) => {

);
if (event.type === 'payment_intent.succeeded') {
await updateUserSubscription(event.data.object.customer);
}
res.status(200).send('ok');
} catch (err) {
console.log('Webhook signature verification failed:', err.message);
res.status(400).send('Webhook Error');
// Stripe won't retry this 😬
