@nguyenchr @vickvu what do you think about betTypeGroup

@nguyenchr After I read again you first comment I got It. I can use sportType : "NRL" or "AFL"

instead of sportType why not use competiton as "NRL" and "AFL" are sport competition

{
  "type": "FOOTY",
  "competition": "NRL",
  "betType": "PICK_THE_MARGINS",
  "stake": "$3.00",
  "flexi": false,
  "matches": [
    ["ALL"],
    [0,1],
    [4,5]
  ]
},
