Item attributes allow you to define specific characteristics for items. Common examples of attributes include size, color, and material. Well-defined attributes are important because they enable item discovery and make catalog management easier.
This endpoint creates and updates item attributes to be assigned later.
1) You can add and manage unlimited attributes for your items. Once they are created, they appear as a selectable option on product pages.
2) In addition, you can assign attributes to items on an individual level or in bulk.
