Webhook providers call a public URL. A local development server usually has no public address, so testing needs a safe bridge between the provider and your machine.
ProviderSends an HTTPS callback after an event such as a payment or push.
Public TunnelReceives the callback at a public URL and forwards it inward.
Local appHandles the webhook on localhost while you inspect and debug it.
Typical webhook testing steps
- Run the app locallyStart the route that will receive the callback.

- Verify the payloadInspect signatures, retries, and business logic without redeploying.
