We want to give our first time purchasers a card in their package that offers 10% off. We integrate with ShipStation and need a way to indicate if someone is making their first purchase so that when the packaging team is putting orders together, they know that it is a first time purchase, and that they need to include the discount card. ShipStation does not offer a way to notify first time purchases.
I thought a good solution would be to add additional script to the checkout page. Maybe like a checkbox that says "First Time Purchase?" I tried a few different html codes and nothing showed up when I did a trial checkout.
Does anyone have any suggestions on how we can either add code to the checkout page or find another way to notify ShipStation that it is a first time purchase?
