What is a 'basket line'?

[San-Zer0-786]

https://api-reference.getcandy.io/#operation/post-basket-lines (A)

I am trying to, simply allow a user to log in via the frontend. They can then add an item to their unique basket (which I presume is done via this endpoint here https://api-reference.getcandy.io/#operation/post-baskets-basketId-claim) and place an order. That's it

In link (A) above, I can see documentation that explains little to nothing. What is the request schema 'Variants'? Does this mean the product variant? So I simply place the product ID and the qty the user on frontend can choose, so the request would be something like:

{
'basketId' : 'here' (i presume you grab this after generating a new basket if user does not have one assigned
'variants': [
'id': "enter ID of the product you wish to add to basket here" (is this righr?)
'quantity': 2
]
}

What is a basket line? Googling leads to explanation regarding basketball

The request schema mentions required field 'name'.

...Name of WHAT exactly?

Why all the mystery?
