+## 3. Optional Event Relay
+
+Set `ADMIN_DASH_URL` to receive same-origin website events as JSON:
+
+```json
+{ "path": "/blog", "visitorId": "daily-hmac-id", "timestamp": 1770000000000 }
+```
+
+If `ADMIN_DASH_KEY` is set, the website sends it as a bearer token. The relay is disabled when `ADMIN_DASH_URL` is empty.
