| Method | Path | Description |
|--------|------|-------------|
| POST | / | Registers a player's acceptance or rejection of a proposed FlexMatch match. A matchmaking configuration may require player acceptance; if so, then matches built with that configuration cannot be completed unless all players accept the proposed match within a specified time limit.  When FlexMatch builds a match, all the matchmaking tickets involved in the proposed match are placed into status REQUIRES_ACCEPTANCE. This is a trigger for your game to get acceptance from all players in each ticket. Calls to this action are only valid for tickets that are in this status; calls for tickets not in this status result in an error. To register acceptance, specify the ticket ID, one or more players, and an acceptance response. When all players have accepted, Amazon GameLift advances the matchmaking tickets to status PLACING, and attempts to create a new game session for the match.  If any player rejects the match, or if acceptances are not received before a specified timeout, the proposed match is dropped. Each matchmaking ticket in the failed match is handled as follows:    If the ticket has one or more players who rejected the match or failed to respond, the ticket status is set CANCELLED and processing is terminated.   If all players in the ticket accepted the match, the ticket status is returned to SEARCHING to find a new match.     Learn more    Add FlexMatch to a game client    FlexMatch events (reference) |
| POST | / | This operation is used with the Amazon 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, Amazon 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 Amazon 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. Add filter options to further restrict how a game server is chosen, such as only allowing game servers on ACTIVE instances to be claimed. 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:   If the game server utilization status is UTILIZED.   If the game server claim status is CLAIMED.   If the game server is running on an instance in DRAINING status and the provided filter option does not allow placing on DRAINING instances.    Learn more   Amazon GameLift FleetIQ Guide |
| POST | / | Creates an alias for a fleet. In most situations, you can use an alias ID in place of a fleet ID. An alias provides a level of abstraction for a fleet that is useful when redirecting player traffic from one fleet to another, such as when updating your game build.  Amazon GameLift supports two types of routing strategies for aliases: simple and terminal. A simple alias points to an active fleet. A terminal alias is used to display messaging or link to a URL instead of routing players to an active fleet. For example, you might use a terminal alias when a game version is no longer supported and you want to direct players to an upgrade site.  To create a fleet alias, specify an alias name, routing strategy, and optional description. Each simple alias can point to only one fleet, but a fleet can have multiple aliases. If successful, a new alias record is returned, including an alias ID and an ARN. You can reassign an alias to another fleet by calling UpdateAlias.  Related actions   All APIs by task |
| POST | / | Creates a new Amazon GameLift build resource for your game server binary files. Combine game server binaries into a zip file for use with Amazon GameLift.   When setting up a new game build for Amazon GameLift, we recommend using the CLI command  upload-build . This helper command combines two tasks: (1) it uploads your build files from a file directory to an Amazon GameLift Amazon S3 location, and (2) it creates a new build resource.  You can use the CreateBuild operation in the following scenarios:   Create a new game build with build files that are in an Amazon S3 location under an Amazon Web Services account that you control. To use this option, you give Amazon GameLift access to the Amazon S3 bucket. With permissions in place, specify a build name, operating system, and the Amazon S3 storage location of your game build.   Upload your build files to a Amazon GameLift Amazon S3 location. To use this option, specify a build name and operating system. This operation creates a new build resource and also returns an Amazon S3 location with temporary access credentials. Use the credentials to manually upload your build files to the specified Amazon S3 location. For more information, see Uploading Objects in the Amazon S3 Developer Guide. After you upload build files to the Amazon GameLift Amazon S3 location, you can't update them.    If successful, this operation creates a new build resource with a unique build ID and places it in INITIALIZED status. A build must be in READY status before you can create fleets with it.

| POST | / | This operation is used with the Amazon GameLift containers feature, which is currently in public preview.   Creates a ContainerGroupDefinition resource that describes a set of containers for hosting your game server with Amazon GameLift managed EC2 hosting. An Amazon GameLift container group is similar to a container "task" and "pod". Each container group can have one or more containers.  Use container group definitions when you create a container fleet. Container group definitions determine how Amazon GameLift deploys your containers to each instance in a container fleet.  You can create two types of container groups, based on scheduling strategy:   A replica container group manages the containers that run your game server application and supporting software. Replica container groups might be replicated multiple times on each fleet instance, depending on instance resources.    A daemon container group manages containers that run other software, such as background services, logging, or test processes. You might use a daemon container group for processes that need to run only once per fleet instance, or processes that need to persist independently of the replica container group.    To create a container group definition, specify a group name, a list of container definitions, and maximum total CPU and memory requirements for the container group. Specify an operating system and scheduling strategy or use the default values. When using the Amazon Web Services CLI tool, you can pass in your container definitions as a JSON file.  This operation requires Identity and Access Management (IAM) permissions to access container images in Amazon ECR repositories. See  IAM permissions for Amazon GameLift for help setting the appropriate permissions.  If successful, this operation creates a new ContainerGroupDefinition resource with an ARN value assigned. You can't change the properties of a container group definition. Instead, create a new one.

| POST | / | This operation has been expanded to use with the Amazon GameLift containers feature, which is currently in public preview.  Creates a fleet of compute resources to host your game servers. Use this operation to set up the following types of fleets based on compute type:   Managed EC2 fleet  An EC2 fleet is a set of Amazon Elastic Compute Cloud (Amazon EC2) instances. Your game server build is deployed to each fleet instance. Amazon GameLift manages the fleet's instances and controls the lifecycle of game server processes, which host game sessions for players. EC2 fleets can have instances in multiple locations. Each instance in the fleet is designated a Compute. To create an EC2 fleet, provide these required parameters:   Either BuildId or ScriptId     ComputeType set to EC2 (the default value)    EC2InboundPermissions     EC2InstanceType     FleetType     Name     RuntimeConfiguration with at least one ServerProcesses configuration   If successful, this operation creates a new fleet resource and places it in NEW status while Amazon GameLift initiates the fleet creation workflow. To debug your fleet, fetch logs, view performance metrics or other actions on the fleet, create a development fleet with port 22/3389 open. As a best practice, we recommend opening ports for remote access only when you need them and closing them when you're finished.  When the fleet status is ACTIVE, you can adjust capacity settings and turn autoscaling on/off for each location.  Managed container fleet  A container fleet is a set of Amazon Elastic Compute Cloud (Amazon EC2) instances. Your container architecture is deployed to each fleet instance based on the fleet configuration. Amazon GameLift manages the containers on each fleet instance and controls the lifecycle of game server processes, which host game sessions for players. Container fleets can have instances in multiple locations. Each container on an instance that runs game server processes is registered as a Compute. To create a container fleet, provide these required parameters:    ComputeType set to CONTAINER     ContainerGroupsConfiguration     EC2InboundPermissions     EC2InstanceType     FleetType set to ON_DEMAND     Name     RuntimeConfiguration with at least one ServerProcesses configuration   If successful, this operation creates a new fleet resource and places it in NEW status while Amazon GameLift initiates the fleet creation workflow.  When the fleet status is ACTIVE, you can adjust capacity settings and turn autoscaling on/off for each location.  Anywhere fleet  An Anywhere fleet represents compute resources that are not owned or managed by Amazon GameLift. You might create an Anywhere fleet with your local machine for testing, or use one to host game servers with on-premises hardware or other game hosting solutions.  To create an Anywhere fleet, provide these required parameters:    ComputeType set to ANYWHERE     Locations specifying a custom location    Name    If successful, this operation creates a new fleet resource and places it in ACTIVE status. You can register computes with a fleet in ACTIVE status.   Learn more   Setting up fleets   Setting up a container fleet   Debug fleet creation issues   Multi-location fleets |
