Webhooks
Growth and Premium. Outbound link.clicked events so you do not poll the API.
Redirects do not wait on your server. Delivery is async. Events are sampled (default about 1 in 10 after a small first-click burst).
Register
Dashboard or POST /v1/webhooks with an https URL. You receive a secret once. HMAC-SHA256 over the raw body; header X-Lit-Signature: sha256=<hex>.
Payload
No raw IP.

Retries with backoff on 5xx and timeouts. Repeated failure disables the endpoint. Re-enable after you fix the receiver.
