Changes the order of products within one category. Requires a producer access token for the application.

You only list the products you want to move, not every product in the category. Each entry has a product_id and an optional zero-based position, and the entries are applied in list order. An entry without a position sends that product to the end. Products you don't list keep their relative order, and a product's position in any other category is not affected. Every product_id must already be in this category.

The response lists every product in the category with its display_order.
