# Webhooks

Webhooks deliver market events to an HTTPS endpoint you register. They are another access path to the same events the application writes. They are not a second source of truth.

Create a subscription from the signed-in developer webhook screen. The signing secret is shown once.

Delivery includes an event id, a delivery id, and a timestamp. Verify the signature before you trust the body. Reject timestamps outside your replay window. Retries continue until the delivery succeeds or the retry budget ends. A failed delivery stays visible on the subscription so you can replay it.

Event names: [catalog](https://breezewish.com/developers/webhooks/events). Signing: [security](https://breezewish.com/developers/webhooks/security).
