 There are certain scenarios where sending a User-ID can be helpful. For example, if you choose to integrate with Google Analytics 4 client-side (using Gtag outside of Segment) _and_ also use Segment's Google Analytics 4 destination to send events via API, you may consider taking the following approach:
 - **Use the Gtag-generated Client ID.** Gtag will set a Client ID automatically. The Client ID is stored in a cookie and can be fetched on the web client. To tie data between client-side and server-side, pass the Gtag-generated Client ID to Segment as a property and use that value as the Client ID in the Google Analytics 4 destination mappings.
 - **Use the Segment `userId` for User-ID.** The Segment `userId` should be your company’s canonical user identifier. By setting Google's User-ID to the same value as `userId` on client-side and server-side, you can benefit from cross-platform analytics.
-In addition, if you use [Firebase to send mobile data to Google Analytics 4](docs/connections/destinations/catalog/actions-google-analytics-4/#mobile-data), using the same User-ID across web and mobile will ensure users are stitched together across devices.
