# In a Server Context

In a server context, managing multiple users is different from a client game. The server typically [impersonates players or exchanges tokens](/server/unreal-server/how-to/unreal-server-impersonation.md) to obtain a Game API session token for each player, then uses the SDK to manage multi user state and make requests for many users in a secure context.

### How it Works

* The server obtains a session token for each player (using impersonation or token exchange).
* The SDK's `StartSessionManual` method is used to add each session to the multi user state.
* You can then make API calls for any player by specifying their ULID.
* Remember to use all the techniques from our guide on [how to end sessions and manage state](/players/multi-user/how-to/end-sessions-and-manage-state.md) so that you have the correct sessions active and ready in your server context.
