[ aws . gamelift ]



Retrieves information, including current status, about a game session placement request.

To get game session placement details, specify the placement ID.

This operation is not designed to be continually called to track game session status. This practice can cause you to exceed your API limit, which results in errors. Instead, you must configure configure an Amazon Simple Notification Service (SNS) topic to receive notifications from FlexMatch or queues. Continuously polling with DescribeGameSessionPlacement should only be used for games in development with low game session usage.

--placement-id (string)

A unique identifier for a game session placement to retrieve.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.


GameSessionPlacement -> (structure)

Object that describes the requested game session placement.

PlacementId -> (string)

A unique identifier for a game session placement.

GameSessionQueueName -> (string)

A descriptive label that is associated with game session queue. Queue names must be unique within each Region.

Status -> (string)

Current status of the game session placement request.

  • PENDING – The placement request is in the queue waiting to be processed. Game session properties are not yet final.
  • FULFILLED – A new game session has been successfully placed. Game session properties are now final.
  • CANCELLED – The placement request was canceled.
  • TIMED_OUT – A new game session was not successfully created before the time limit expired. You can resubmit the placement request as needed.
  • FAILED – Amazon GameLift is not able to complete the process of placing the game session. Common reasons are the game session terminated before the placement process was completed, or an unexpected internal error.

GameProperties -> (list)

A set of key-value pairs that can store custom data in a game session. For example: {"Key": "difficulty", "Value": "novice"} .


This key-value pair can store custom data about a game session. For example, you might use a GameProperty to track a game session’s map, level of difficulty, or remaining time. The difficulty level could be specified like this: {"Key": "difficulty", "Value":"Novice"} .

You can set game properties when creating a game session. You can also modify game properties of an active game session. When searching for game sessions, you can filter on game property keys and values. You can’t delete game properties from a game session.

For examples of working with game properties, see Create a game session with properties .

Key -> (string)

The game property identifier.

Value -> (string)

The game property value.

MaximumPlayerSessionCount -> (integer)

The maximum number of players that can be connected simultaneously to the game session.

GameSessionName -> (string)

A descriptive label that is associated with a game session. Session names do not need to be unique.

GameSessionId -> (string)

A unique identifier for the game session. This value isn’t final until placement status is FULFILLED .

GameSessionArn -> (string)

Identifier for the game session created by this placement request. This identifier is unique across all Regions. This value isn’t final until placement status is FULFILLED .

GameSessionRegion -> (string)

Name of the Region where the game session created by this placement request is running. This value isn’t final until placement status is FULFILLED .

PlayerLatencies -> (list)

A set of values, expressed in milliseconds, that indicates the amount of latency that a player experiences when connected to Amazon Web Services Regions.


Regional latency information for a player, used when requesting a new game session. This value indicates the amount of time lag that exists when the player is connected to a fleet in the specified Region. The relative difference between a player’s latency values for multiple Regions are used to determine which fleets are best suited to place a new game session for the player.

PlayerId -> (string)

A unique identifier for a player associated with the latency data.

RegionIdentifier -> (string)

Name of the Region that is associated with the latency value.

LatencyInMilliseconds -> (float)

Amount of time that represents the time lag experienced by the player when connected to the specified Region.

StartTime -> (timestamp)

Time stamp indicating when this request was placed in the queue. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057" ).

EndTime -> (timestamp)

Time stamp indicating when this request was completed, canceled, or timed out.

IpAddress -> (string)

The IP address of the game session. To connect to a Amazon GameLift game server, an app needs both the IP address and port number. This value isn’t final until placement status is FULFILLED .

DnsName -> (string)

The DNS identifier assigned to the instance that is running the game session. Values have the following format:

  • TLS-enabled fleets: <unique identifier>.<region identifier>.amazongamelift.com .
  • Non-TLS-enabled fleets: ec2-<unique identifier>.compute.amazonaws.com . (See Amazon EC2 Instance IP Addressing .)

When connecting to a game session that is running on a TLS-enabled fleet, you must use the DNS name, not the IP address.

Port -> (integer)

The port number for the game session. To connect to a Amazon GameLift game server, an app needs both the IP address and port number. This value isn’t final until placement status is FULFILLED .

PlacedPlayerSessions -> (list)

A collection of information on player sessions created in response to the game session placement request. These player sessions are created only after a new game session is successfully placed (placement status is FULFILLED ). This information includes the player ID, provided in the placement request, and a corresponding player session ID.


Information about a player session. This object contains only the player ID and player session ID. To retrieve full details on a player session, call DescribePlayerSessions with the player session ID.

PlayerId -> (string)

A unique identifier for a player that is associated with this player session.

PlayerSessionId -> (string)

A unique identifier for a player session.

GameSessionData -> (string)

A set of custom game session properties, formatted as a single string value. This data is passed to a game server process in the GameSession object with a request to start a new game session (see Start a Game Session ).

MatchmakerData -> (string)

Information on the matchmaking process for this game. Data is in JSON syntax, formatted as a string. It identifies the matchmaking configuration used to create the match, and contains data on all players assigned to the match, including player attributes and team assignments.
