Active Merchant

Active Merchant is an extraction from the e-commerce system Shopify. Shopify's requirements for a simple and unified API to access dozens of different payment gateways with very different internal APIs was the chief principle in designing the library.

Active Merchant has been in production use since June 2006 and is now used in most modern Ruby applications which deal with financial transactions.

It was developed for usage in Ruby on Rails web applications and integrates seamlessly as a plugin but it also works excellently as a stand alone library.

See {file:GettingStarted.md} if you want to learn more about using Active Merchant in your applications.

Usage

This simple example demonstrates how a purchase can be made using a person's credit card details.

require 'rubygems'
require 'active_merchant'

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

gateway = ActiveMerchant::Billing::TrustCommerceGateway.new(
            :login => 'TestMerchant',
            :password => 'password')

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

# 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?
  # Capture $10 from the credit card
  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
