question

Hello! I have a question about matchmaking quick start.

PlayFabMultiplayerAPI.CreateMatchmakingTicket(
    new CreateMatchmakingTicketRequest
    {
        // The ticket creator specifies their own player attributes.
        Creator = new MatchmakingPlayer
        {
            Entity = new EntityKey
            {
                Id = "<Entity ID goes here>",
                Type = "<Entity type goes here>",
            },


            // Here we specify the creator's attributes.
            Attributes = new MatchmakingPlayerAttributes
            {
                DataObject = new
                {
                    Skill = 24.4
                },
            },
        },


        // Cancel matchmaking if a match is not found after 120 seconds.
        GiveUpAfterSeconds = 120,


        // The name of the queue to submit the ticket into.
        QueueName = "myqueue",
    },


    // Callbacks for handling success and error.
    this.OnMatchmakingTicketCreated,
    this.OnMatchmakingError);

Do I have to fill in Skill = 24.4 on the client? I think it's not safe.

1. Should I implement this feature with a cloud script?

2. How can I use a cloud script to listen for the matchmaking_match_found event;

Thanks!
