Everything runs in your browser. Payloads are never uploaded, but avoid pasting live secrets anyway.
Working with webhook payloads
A webhook is an HTTP POST that a service sends to your URL when something happens:
a payment succeeds, a pull request opens, a form is submitted. The body is almost always JSON, and
the first job is usually finding the handful of fields your handler needs in a deeply nested
object.
Fields worth finding first
- Event type (
type,event,action): route the payload to the right handler. - Event ID (
id): store it and skip duplicates. Most providers retry, so handlers must be idempotent. - Timestamp (
created,created_at): reject stale events and order out-of-order deliveries. - Mode (
livemode,test): don't let test events touch production data. - Amounts: usually integers in minor units (4900 = $49.00).
Path syntax
Paths use JavaScript-style access: data.object.id, items[0].sku (or
items.0.sku), and headers["content-type"] for keys that aren't valid
identifiers. The same paths work in most automation tools and in jq with a leading dot.
Security
Always verify the signature header (Stripe-Signature, X-Hub-Signature-256,
X-Slack-Signature, …) server-side against the raw request body before trusting a
payload. This inspector is for reading and debugging only. It never sends your data anywhere.
If a webhook fires on a schedule, check the timing with the
Cron Expression Explainer.
