This operation is used with the GameLift FleetIQ solution and game server groups.

Locates an available game server and temporarily reserves it to host gameplay and players. This operation is called from a game client or client service (such as a matchmaker) to request hosting resources for a new game session. In response, GameLift FleetIQ locates an available game server, places it in CLAIMED status for 60 seconds, and returns connection information that players can use to connect to the game server.

To claim a game server, identify a game server group. You can also specify a game server ID, although this approach bypasses GameLift FleetIQ placement optimization. Optionally, include game data to pass to the game server at the start of a game session, such as a game map or player information.

When a game server is successfully claimed, connection information is returned. A claimed game server's utilization status remains AVAILABLE while the claim status is set to CLAIMED for up to 60 seconds. This time period gives the game server time to update its status to UTILIZED after players join. If the game server's status is not updated within 60 seconds, the game server reverts to unclaimed status and is available to be claimed by another request. The claim time period is a fixed value and is not configurable.

If you try to claim a specific game server, this request will fail in the following cases:

When claiming a specific game server, this request will succeed even if the game server is running on an instance in DRAINING status. To avoid this, first check the instance status by calling DescribeGameServerInstances .
