i came across this in order to add items to my cart from a url http://shopping.na3.netsuite.com/app/site/query/additemtocart.nl?c=1019389&n=3&buyid=10230&qty=1 is it Is it possible to use this with an array of items I have tried adding buyid[]=item , and buyid=[item, item]

you need to use the “multi” to add multiple items, there is documentation about this in help guide.

Got it thank you
