Example

Webhook Payload Inspector

{
  "event": "order.created",
  "id": "evt_3F9a2K",
  "created_at": "2026-08-21T09:14:02Z",
  "data": {
    "order_id": "ord_1029",

  }
}

Example shown — paste your own payload to inspect.

data.customer is a nested object

How it works

  1. Paste a raw webhook payload.
  2. It's pretty-printed and summarized — top-level keys and nesting depth.
  3. Copy the summary into a ticket or a code review comment.

FAQ

What does the structure summary tell me?

The top-level keys, how deeply the payload is nested, and which fields are nested objects — a fast way to sanity-check a payload's shape before you write a parser for it.

Does this validate against a specific webhook provider?

No — it works on any well-formed JSON payload, regardless of which service sent it (Stripe, GitHub, a custom internal webhook, etc.).

Is the payload I paste sent anywhere?

No — everything is inspected locally in your browser. This matters since webhook payloads often contain customer or transaction data.
