 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 through the API, you can track sessions server-side. When using Gtag, [Google generates a `session_id` and `session_number` when a session begins](https://support.google.com/analytics/answer/9191807?hl=en){:target='_blank'}. The `session_id` and `session_number` generated on the client can be passed as Event Parameters to stitch events sent through the API with the same session that was collected client-side.

 > info "Session tracking limitations"
 > Session tracking server-side only works if you're also sending data to Google Analytics 4 client-side. This is because the `session_id` must match a value that was previously collected on the client. For events to stitch properly, they must arrive within a 48 hour window of when the client-side events arrived.
