# Category

The `Category` family — 7 operations.

Categories form your merchandise tree — the departments and sub-departments your range hangs from. Only leaf categories (ones without children) take product placements, so the tree stays tidy.

## Operations

| Operation | Kind | What it does |

| [createCategory](/reference/category/createCategory/) | mutation | Create a new category — the product tree’s branches at your organization. |
