Affirm Merchant Help

Set a Price Floor for Checkout (Shopify Plus only)

Merchants using Shopify Plus can set a price floor that displays Affirm as a payment option when the customer's cart exceeds a minimum dollar amount.

  1. Go to the Shopify script editor
  2. Click Create Script
  3. Choose Payment Gateway for the script type
  4. Choose Blank Template
  5. Click Create Script
  6. In the Title box, enter Affirm price floor as the script name
  7. Click Code to open the Ruby source code console
  8. Paste the following code into the console (250 sets the floor to $250. You can change it to your desired price floor)
available_gateways = Input.payment_gateways
cart = Input.cart
subtotal = cart.subtotal_price
unless cart.line_items.empty? or cart.discount_code.nil?
  case cart.discount_code
  when CartDiscount::Percentage
    if cart.subtotal_price >= cart.discount_code.minimum_order_amount
      subtotal = cart.subtotal_price * ((Decimal.new(100) - cart.discount_code.percentage) / 100)
    else
      subtotal = cart.subtotal_price
    end
  when CartDiscount::FixedAmount
    if cart.subtotal_price >= cart.discount_code.minimum_order_amount
      subtotal = cart.subtotal_price - cart.discount_code.amount
    else
      subtotal = cart.subtotal_price
    end
  else
    subtotal = cart.subtotal_price
  end
end
if subtotal < Money.new(cents:100) * 250
  available_gateways = available_gateways.delete_if do |payment_gateway|
    payment_gateway.name == "Affirm"
  end
end
Output.payment_gateways = available_gateways
 
  1. Click Run Script
  2. Click Save and Publish

The price floor takes effect immediately. Test it by attempting a checkout for an item less than the price floor amount.
