Create SKU attribute

Creates an attribute for an SKU, which is an informative field at the SKU level that doesn't create new variants. For example, a lipstick might have color and size as structured specifications that define SKU variants, while ingredients would be an informative attribute since they don't represent a new SKU.

⚠️ Attributes only accept open-text values. The maximum length for SpecificationValue is 3,500 characters. If the request body contains characters that break the JSON string (for example, unescaped backslashes), the request will fail with a 400 status code.

You can also create and edit attributes via VTEX Admin, in Catalog > Products and SKUs > SKU editing page in the Attributes section.
