Active Merchant is a simple payment abstraction library used in and sponsored by Shopify. It is written by Tobias Luetke, Cody Fauser, and contributors. The aim of the project is to feel natural to Ruby users and to abstract as many parts as possible away from the user to offer a consistent interface across all supported gateways.

# ActiveMerchant accepts all amounts as Integer values in cents
# $10.00
amount # 1000

# The card verification value is also known as CVV2, CVC2, or CID 
credit_card # ActiveMerchant::Billing::CreditCard.new(
                :first_name         #> 'Bob',
                :last_name          #> 'Bobsen',
                :number             #> '4242424242424242',
                :month              #> '8',
                :year               #> '2012',
                :verification_value #> '123'
              )

# Validating the card automatically detects the card type
if credit_card.valid?

  # Create a gateway object for the TrustCommerce service
  gateway # ActiveMerchant::Billing::TrustCommerceGateway.new(
              :login #> 'TestMerchant',
              :password #> 'password'
            )

  # Authorize for the amount
  response # gateway.purchase(amount, credit_card)

  if response.success?
    puts "Successfully charged $#{sprintf("%.2f", amount / 100)} to the credit card #{credit_card.display_number}"
  else
    raise StandardError, response.message 
  end
