Clarification on the ability to use undocumented API endpoint

[adimmitt]

When trying to get the list of categories to use in sending to Birdeye. We found in the documentation this API: https://developers.birdeye.com/#/reference/category/all-categories/get-all-categories which calls this route: https://api.birdeye.com/resources/v1/category/all.

This lists all categories like:

[
    "3D Printing",
    "Acai Bowls",
    "Accessories",
    "Accountants",
    "Acne Treatment",
    "Acupuncture",
    "Addiction Medicine",
    "Adoption Services",
    ....
]

but does not have the details of their hierarchy of them.

We found that the API route https://api.birdeye.com/resources/v1/category returns the desired details like:

[
    {
        "id": 1,
        "name": "Advertising / Media / Agency",
        "childCategories": [
            {
                "id": 30,
                "name": "Reputation Management",
                "childCategories": [],
                "coverImageUrl": "advertising-media.jpg",
                "schemaType": null
            },
            {
                "id": 1299,
                "name": "Advertising / Media / Agency",
                "childCategories": [],
                "coverImageUrl": "advertising-media.jpg",
                "schemaType": null
            },
            ...
]

Is this an acceptable route to use for development to get the list of appropriate categories and subcategories?
