Stripe Webhook Tester — Test & Inspect Online

If you are wiring up Stripe webhooks, the first question is always the same: what does Stripe actually send? The docs show an idealised payload, but the real request — its headers, its Stripe-Signature header, the exact JSON shape — is what your handler has to parse. A Stripe webhook tester gives you a public URL that captures those real requests so you can read every byte before you write any code.

Get a free Stripe webhook tester URL

The fastest way is our free Webhook Bin — a no-code webhook tester that gives you an instant public URL and stores every request that hits it, headers and body included. No signup, no deploy:

1. Open the Webhook Bin and copy the URL it generates for you.
2. In Developers → Webhooks in the Stripe Dashboard, add a webhook endpoint and paste that URL.
3. Trigger an event (see below) and watch the request land in the bin in real time.

Because the bin keeps the full request, you can inspect the Stripe-Signature header, the Content-Type, and the complete payload — the three things you need to build and verify a handler.

What a Stripe webhook looks like

Stripe delivers webhooks as an HTTP POST with a application/json body. Stripe lets you fire test events straight from the dashboard or with the Stripe CLI, so you can replay a real payment_intent.succeeded into your bin and read every field it actually sends.

A typical payment_intent.succeeded payload looks like this:

{
  "id": "evt_1P...",
  "object": "event",
  "type": "payment_intent.succeeded",
  "data": {
    "object": {
      "id": "pi_3P...",
      "object": "payment_intent",
      "amount": 1999,
      "currency": "usd",
      "status": "succeeded"
    }
  }
}

Common Stripe events you will want to test:

• payment_intent.succeeded
• checkout.session.completed
• customer.subscription.updated
• invoice.paid

Verifying the Stripe signature

Stripe signs each request so you can prove it really came from Stripe. The signature travels in the Stripe-Signature header and is HMAC-SHA256 computed over timestamp.payload, using a signing secret that starts with whsec_. Capture a real request first, then use our Stripe signature verifier and the verify a webhook signature guide to confirm your verification logic against a payload you can actually see.

From inspecting to receiving on localhost

A bin is perfect for seeing the payload. When you are ready to drive your local handler with real Stripe events — without deploying — forward them straight to localhost with the Webhook Relay agent. The full walkthrough is here: Receive Stripe webhooks on localhost.

That gives you a stable public URL that tunnels to your machine, so Stripe keeps delivering to the same endpoint while you iterate on localhost, no firewall changes or public IP required.

Test Stripe webhooks online in three steps

1. Capture — point Stripe at a Webhook Bin URL and inspect the real request.
2. Verify — confirm the Stripe-Signature header with the Stripe signature verifier.
3. Forward — when the shape is clear, receive Stripe webhooks on localhost and build your handler.
