# Category entity

Please check the sample-data/categories.json to be sure which fields are critical for Storefront API to work.

Remember - you can add any properties you like to the JSON objects to consume them on the Storefront API level. Please make sure you added the new property names to the proper includeFields list for queries.

Here we present the core purpose of the product properties:

    "id": 24,

The type is undefined (it can be anything) - but must be unique. The category identifier is used mostly for caching purposes (as a key).

    "parent_id": 21,

If this is a child category, please set the parent category id in here. This field is used for building up Breadcrumbs.

    "path": "1/2/29",

This is a string, a list of IDs of the parent categories. It's used to build Breadcrumbs more easily.

    "name": "Hoodies & Sweatshirts",

This is just a category name.

    "url_key": "hoodies-and-sweatshirts-24",
    "url_path": "women/tops-women/hoodies-and-sweatshirts-women/hoodies-and-sweatshirts-24",

    "is_active": true,

If it's false, the category won't be displayed.

    "position": 2,

Sorting position of the category on its level.

  "level": 4,

The category level in the tree. By default, Storefront API displays categories with level: 2 in the main menu.

    "product_count": 182,

If it's false, the category won't be displayed.

    "children_data": [
      {
        "id": 27,
        "children_data": []
      },
      {
        "id": 28,
        "children_data": []
      }
    ]

Here is the children structure. It's used for constructing queries to get the child products.
