Hi Rob,
I know this a couple of years ago, but I was hoping you could help me if possible.
I’m trying to keep the current basket while adding a link that adds multiple products, however it does not work the same way with the /add URL as it does with the /update URL. It simple gives and error message.
Ultimately I want to make a URL that adds multiple items (and quantities) to the current basket without taking away the contents.
I’m trying this;
https://store.com/cart/add?id[]=48578639298870=2&add?id[]=48588645794102=3
this work when you take away everything up to the quanity entry. example; https://store.com/cart/add?id[]=48578639298870 works.
