{
"listNavigationalCatalogs": {
"items": [
{
"catalogCategories": {
"items": [
{
"categoryTheme": {
"backgroundColor": {
"blue": 226,
"green": 215,
"red": 163
},
"descriptionColor": null,
"indicatorColor": {
"red": 54,
"green": 186,
"blue": 228
},
"selectedColor": null,
"unSelectedColor": null
},
"description": "Adventure Sports",
"button": {
"color": {
"blue": 228,
"green": 186,
"red": 54
},
"text": "SEE ALL",
"textColor": null
},
"image": "https://i.postimg.cc/pLjSRBvn/adv.jpg",
"name": "Adventure",
"priority": 3,
"_deleted": null
}
]
},

"interval": 1,
"fetchedDate": "2021-11-25T00:00Z",
"fetchRealTime": false,
