Implement hotproducts(promo-code-info) and smart match products

The response "promo-code-info" of the function "hotproducts" is not implemented.

The "Smart Match Products" and "Get Featuredpromo Products" function is also not implemented.

Does anyone happen to know how to get these functions working? Or even if there's an update of this API that you could send me.

I'm new to the API world, still finding ways to learn.

Thank you very much!!
