Adding Price To Cart

Hello,



I am just beginning to look into the cs-cart api and from what I've read so far it seems the functionality I keep seeing for getting a custom price/description of a product into a users cart would be for me to create a custom product(http://docs.cs-cart…ate-object-post) > add the product to users cart(add to cart button functionality) > redirect them to checkout. My question being is there any way for me to skip creating the product and simply add a custom description/price straight to the users cart through any methods in HTML, Javascript, or PHP?



Thank you for your responses.
