# Parametric ## List category focus parametrics - [GET /ListFocusParametrics](https://docs.norce.io/api-reference/services/productservice/openapi/parametric/listfocusparametrics.md): Available focus parametrics on a category. Focus parametrics is used when filtering a ListProduct result set. ## List product parametric groups - [GET /ListParametricGroups](https://docs.norce.io/api-reference/services/productservice/openapi/parametric/listparametricgroups.md): Lists all parametric groups for the client. ## List parametric metadata - [GET /ListParametricInfo](https://docs.norce.io/api-reference/services/productservice/openapi/parametric/listparametricinfo.md): Lists metadata for parametric, ParametricInfos. ## List parametric list values - [GET /ListParametricValues2](https://docs.norce.io/api-reference/services/productservice/openapi/parametric/listparametricvalues2.md): Reference list of Parametric values. ## List product parametrics - [GET /ListProductParametrics](https://docs.norce.io/api-reference/services/productservice/openapi/parametric/listproductparametrics.md): Lists Product Parametric values for a product. What parametric values are returned is defined in the primary Category of the product, or if no primary exists, the first category by sort order. If the product does not exist or does not have a category an empty list is returned. Sort order of the parametric values is taken from the order defined for the category.
