        {
          "name": "Dual Handle Cardio Ball",
          "url_key": "dual-handle-cardio-ball",
          "gender": ["Men","Women","Unisex"]
        }
      ]
    }
  }
}

  "data": {
    "productDetail": {
      "items": [
        {
          "name": "Dual Handle Cardio Ball",
          "url_key": "dual-handle-cardio-ball",
