# Get Attribute Set

Returns a single attribute set identified by id. Accepted values:
- default (case-insensitive) — retrieves the tenant's default attribute set.
- Positive integer — retrieves the attribute set with that numeric ID.
            
Any other value is rejected with 400 Bad Request.
            
The response includes the attribute set name and its form layout configuration for Products
and Variants (ProductLayout, VariantLayout). When the set has no Variant layout configured,
VariantLayout and VariantAttributeIds are omitted from the response.
