# Uninstall reporting

> Report removals using your uninstall page.

Uninstall reporting is optional. Provide your uninstall page URL in the extension setup, then initialize the website SDK on that page and call:

```typescript theme={null}
import { analytics } from "@crxbase/analytics/web";

analytics.init({ projectId: "YOUR_PROJECT_ID" });
await analytics.recordUninstall();
```

You can use an existing uninstall page, including one with a survey. The SDK will register the page with the information needed to associate a removal with its installation.

Browsers support one uninstall URL per extension. Provide your existing page URL to the SDK rather than registering a second URL. A removal may not be recorded if the page does not open or the request fails.
