Hello. Very new to all of this, so bare with me!
So I want to start an UberEats style app where you can order items from a store and get it delivered to your house. But let’s use Walmart as an example. They have a TON of items. Do I have to add each individual item that the store carries, or is there a way to direct users to a specific Walmart’s website, have them place items in a cart from that website, and have those items transferred over to my app to finalize checkout?
