Shopify Plus + Scripts

Shopify is deprecating Checkout Scripts! Inteligems highly recommends using functions instead.

Add useIgCart()

• Use the useIgCart() hook if your site uses the Storefront Cart API

• Wrap ATC calls with the wrapCustomAttributes function returned by useIgCart

Add Intelligems Script to checkout.liquid

The Intelligems script may be found under settings at app.intelligems.io. Copy this script tag and add it to the header of checkout.liquid

Add Intelligems Checkout Script to Script Editor

Add the following script to your Script Editor app as a Line Item discount.

class Intelligems
  def initialize(discount_property = '_igp', allow_free = false)
    @volume_discount_property = '_igvd'
    @volume_discount_message_property = '_igvd_message'
    @depreciated_property = '_igLineItemDiscount'
    @discount_property = discount_property
    @allow_free = allow_free
  end

  def discount_product(line_item)
    ig_price = Money.new(cents: line_item.properties[@discount_property])

    discount = line_item.line_price - ig_price
    if discount > Money.zero
      discount *= line_item.quantity
      line_item.change_line_price(line_item.line_price - discount, message: 'Discount')
    end

  end

  def depreciated_discount_product(line_item)
    discount = Money.new(cents: line_item.properties[@depreciated_property])
    discount *= line_item.quantity

    if @allow_free or discount < line_item.line_price
      line_item.change_line_price(line_item.line_price - discount, message: 'Intelligems')
    end
  end

  def volume_discount(line_item)
    discount = Money.new(cents: line_item.properties[@volume_discount_property])
    discount *= line_item.quantity

    if discount < line_item.line_price
      message = line_item.properties[@volume_discount_message_property]
      line_item.change_line_price(line_item.line_price - discount, message: message)
    end
  end

  def run(cart)
    cart.line_items.each do |line_item|
      if !line_item.properties[@discount_property].nil? && !line_item.properties[@discount_property].empty?
        discount_product(line_item)
      elsif !line_item.properties[@volume_discount_property].nil? && !line_item.properties[@volume_discount_property].empty?
        volume_discount(line_item)
      elsif !line_item.properties[@depreciated_property].nil? && !line_item.properties[@depreciated_property].empty?
             depreciated_discount_product(line_item)
      end
    end
  end
end

intelligems = Intelligems.new()
intelligems.run(Input.cart)

Output.cart = Input.cart
