I am trying to update line's item quantity with API and can not find qty attribute on "LineItem" API.
In my example, I am trying to increase number of sold pancakes from 1 to 3. I am starting with:
Super Pancakes1 @ $13.23/
and executed:
```
Header key=[Authorization] val=[Bearer aa-*************************-4d]
Payload=[{"name":"Super Pancakes","price":1323,"unitQty":3000}]
```
My objective is to have
3 @ $13.23/
I am realizing that `unitQty`relates to price; however, I could not find any attribute that would relate to just quantity.
