Which webhook providers does this tool recognize?

Currently the tool detects Stripe (presence of object with livemode and type fields), GitHub (presence of repository.full_name and sender), and Slack (presence of team_id and api_app_id or event.type). Unknown payloads are still formatted and displayed without annotation.

Can I use this to test my webhook handler?

The tool is read-only — it formats and annotates existing payloads. To send test events to your handler, use the provider's test event dashboard (Stripe Dashboard, GitHub webhook test delivery, etc.).

Is the payload sent anywhere?

No. The payload stays in your browser. This tool is entirely client-side — paste your payload and everything is processed locally.

Webhook Payload Formatter accepts a raw JSON webhook payload, pretty-prints it, and attempts to detect the provider by inspecting the payload shape. For Stripe events it shows the event type and object id. For GitHub webhooks it highlights the action, repository, and sender. For Slack events it surfaces the event type and team. The formatted JSON and provider annotations make it easy to understand what happened and write handler logic. All processing runs in your browser.
