Kits as reward

Hi, has anybody used kits as reward before? I cant seem to make it work. Am i doing things correctly? 

    {
      "Invites Amount": 1,
      "ID": 1,
      "Show Description": false,
      "Description": [],
      "Type": "Kit",
      "Image": "",
      "Title": "",
      "Command (%steamid%)": "",
      "Kit": "Trailblazer",
      "Plugin": {
        "Hook": "API_OpenPlugin",
        "Plugin name": "Kits",
        "Amount": 0,
        "(GameStores) Store ID in the service": "UNDEFINED",
        "(GameStores) Server ID in the service": "UNDEFINED",
        "(GameStores) Secret Key": "UNDEFINED"
      },

In your case it would be better to issue via console command
