In the following list, the required parameters are described first.

Name

A unique identifier for the matchmaking configuration to update. You can use either the configuration name or ARN value.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: [a-zA-Z0-9-\.]*|^arn:.*:matchmakingconfiguration\/[a-zA-Z0-9-\.]*

Required: Yes

AcceptanceRequired

A flag that indicates whether a match that was created with this configuration must be accepted by the matched players. To require acceptance, set to TRUE. With this option enabled, matchmaking tickets use the status REQUIRES_ACCEPTANCE to indicate when a completed potential match is waiting for player acceptance.

For example, if the configuration's rule set specifies a match for a single 12-person team, and the additional player count is set to 2, only 10 players are selected for the match. This parameter is not used if FlexMatchMode is set to STANDALONE.

Type: Integer

Valid Range: Minimum value of 0.

Required: No

BackfillMode

The method that is used to backfill game sessions created with this matchmaking configuration. Specify MANUAL when your game manages backfill requests manually or does not use the match backfill feature. Specify AUTOMATIC to have GameLift create a StartMatchBackfill request whenever a game session has one or more open slots. Learn more about manual and automatic backfill in Backfill Existing Games with FlexMatch. Automatic backfill is not available when FlexMatchMode is set to STANDALONE.

Type: Array of GameProperty objects

Array Members: Maximum number of 16 items.

Required: No

GameSessionData

A set of custom game session properties, formatted as a single string value.
