Defines a new matchmaking configuration for use with FlexMatch. Whether your are using FlexMatch with Amazon GameLift hosting or as a standalone matchmaking service, the matchmaking configuration sets out rules for matching players and forming teams. If you're also using Amazon GameLift hosting, it defines how to start game sessions for each match. Your matchmaking system can use multiple configurations to handle different game scenarios. All matchmaking requests identify the matchmaking configuration to use and provide player attributes consistent with that configuration.

To create a matchmaking configuration, you must provide the following: configuration name and FlexMatch mode (with or without Amazon GameLift hosting); a rule set that specifies how to evaluate players and find acceptable matches; whether player acceptance is required; and the maximum time allowed for a matchmaking attempt. When using FlexMatch with Amazon GameLift hosting, you also need to identify the game session queue to use when starting a game session for the match.

In addition, you must set up an Amazon Simple Notification Service topic to receive matchmaking notifications. Provide the topic ARN in the matchmaking configuration.

AcceptanceRequiredboolean required

A flag that determines whether a match that was created with this configuration must be accepted by the matched players. To require acceptance, set to <code>TRUE</code>.
