Active Merchant

This library is supposed to aid in creating e-commerce software in Ruby. In the future we want to support all "good" payment gateways.

This library is the foundation of commerce for www.shopify.com.

Please visit the ActiveMerchant homepage for more resources, tutorials and other information about this project.

Supported Direct Payment Gateways

The ActiveMerchant Wiki contains a table of features supported by each gateway.

  # Use the TrustCommerce test servers
  ActiveMerchant::Billing::Base.mode = :test

  # 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',

                  :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
  end
