How to extract fields from webhook payloads using jsonpath
- Step 1Get a sample webhook payload — Use the platform's webhook testing tool (Stripe Dashboard →’ Developers →’ Webhooks →’ Send test event), or capture a real payload from your ngrok tunnel or webhook.site temporary endpoint.
- Step 2Paste the payload — Paste the full webhook JSON. Stripe payloads have a data.object wrapper; GitHub payloads have a top-level event structure. The tool handles both.
- Step 3Write extraction expressions for each field you need — For Stripe: $.data.object.customer for the customer ID, $.data.object.amount for payment amount, $.type for the event type. Build and verify each expression against the real payload.
- Step 4Use the expressions in your webhook handler — Use the verified JSONPath strings in your handler code with jsonpath-plus (Node.js) or jsonpath-ng (Python), or use equivalent object destructuring now that you know the exact field path.
Frequently asked questions
How do I route different event types to different handler functions?+
Extract $.type (Stripe) or $.action (GitHub) with a JSONPath expression. In your handler, use a switch statement or a handler registry keyed by event type string. The JSONPath confirms the exact key name and nesting level for the event type field.
Can I use JSONPath to validate that a webhook contains expected fields before processing?+
Yes. Run presence-check expressions before processing: if jsonpath(payload, '$.data.object.customer') is empty, reject the event. This is useful for defensive webhook processing where missing fields should trigger a rejection rather than a partial update.
Is the webhook payload — including payment data — transmitted to JAD Apps?+
No. JSONPath evaluation runs entirely in your browser. Webhook payloads including payment amounts, customer IDs, and order data are never transmitted to JAD Apps servers.
