Update SKU attribute

Updates an existing attribute of an SKU.

⚠️ 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 status code 400 error.

Permissions

Any user or API key must have at least one of the appropriate License Manager resources to be able to successfully run this request. Otherwise they will receive a status code 403 error. These are the applicable resources for this endpoint:

ProductCategoryResource
Catalog APIGeneralEdit Product

There are no applicable predefined roles for this resource list. You must create a custom role and add at least one of the resources above in order to use this endpoint. To learn more about machine authentication at VTEX, see Authentication overview.

❗ To prevent integrations from having excessive permissions, consider the best practices for managing API keys when assigning License Manager roles to integrations.
