Hi,
I installed NopCommerce version 4.10 in our localhost, and Installed  Web API plugin (https://www.nopcommerce.com/p/2464/api-plugin.aspx) But I couldn't find the api documentation or API details for order and order items. I was able to find the products and customer API details.
Can someone please provide required API details for the following Categories

ProductCategoryMappings
Orders
OrderItems
ShoppingCartItemsCategories
ProductCategoryMappings

ShoppingCartItems
Also can someone provide access token generation api.
