FAQ

How does webhook validation work?

You define a JSON Schema for each endpoint. When a payload arrives, it is validated against that schema. Failures trigger an alert and are logged in your dashboard.

Which services can I monitor?

Any service that sends HTTP webhooks — Stripe, GitHub, Shopify, Twilio, or your own internal APIs. Just point them at your unique WebhookGuard URL.

What happens if my schema changes?

You can update your schema at any time. WebhookGuard will alert you if incoming payloads no longer match, so you catch breaking changes before they affect production.
