# Attributes

> A read-only view over both attribute strings and attribute lists.

An **Attribute** is the **read-only, unified view** over the two kinds of category attribute - [attribute strings](/api/product-management/attribute-strings/) and [attribute lists](/api/product-management/attribute-lists/). It exposes the fields they share (`name`, `categories`), so you can list or read every attribute of a category regardless of its kind.

To **create or modify** an attribute, use its specific resource ([attribute strings](/api/product-management/attribute-strings/) or [attribute lists](/api/product-management/attribute-lists/)) - this resource is read-only.

This resource is read-only - it has no create, update or delete operations.
