# 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.

See also: A legacy OData-style version of this endpoint is available at GET /AttributeSets({attributeSetIdentifier}).
