The `variation_matrix` can then be added to your catalogs.The order of the variations in the `variation_matrix` is the order of the variations in the array when the variations were linked to the product. For example, the first variation in the `variation_matrix` corresponds to the first variation in the array, and so on. You can use the `sort_order`attribute to sort the order of your variation and variation options in the `variation_matrix` object. The sort order value is visible when you add the variations and variation options to your catalogs. You can then use the `sort_order` value to program your storefront to display the variations and variation options in the order that you want.Add the `sort_order` attribute to the body of your request and specify a `sort_order` value. A `sort_order` value must be a number. You can specify any numbers that you want.- 1, 2, 3, or 100, 90, 80, and so on.- Zero or negative numbers.You can set `sort_order` to either `null` or omit it entirely from the request if you wish to remove an existing `sort_order` attribute.:::caution- Commerce does not sort variations and variation options. You must program your storefront to sort the variations and variation options in the order that you want.- You must rebuild your products for the sort order changes to take effect.
