# Active Merchant Active Merchant is an extraction from the e-commerce system [Shopify](http://www.shopify.com). 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. ## Installation ### From Git You can check out the latest source from git: git clone git://github.com/Shopify/active_merchant.git ### As a Rails plugin ActiveMerchant includes an init.rb file. This means that Rails will automatically load ActiveMerchant on startup. Run the following command from the root directory of your Rails project to install ActiveMerchant as a Rails plugin: script/plugin install git://github.com/Shopify/active_merchant.git ### From RubyGems Installation from RubyGems gem install activemerchant Alternatively, add the following to your Gemfile gem 'activemerchant', :require => 'active_merchant' ## 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 For more in-depth documentation and tutorials, see {file:GettingStarted.md} and the [API documentation](http://rubydoc.info/github/Shopify/active_merchant/master/file/README.md). ## Supported Direct Payment Gateways The [ActiveMerchant Wiki](http://github.com/Shopify/active_merchant/wikis) contains a [table of features supported by each gateway](http://github.com/Shopify/active_merchant/wikis/gatewayfeaturematrix). * [Authorize.Net](http://www.authorize.net/) -
