The Authorize.Net Ruby SDK is meant to offer an alternate object-oriented model of development with the Authorize.net APIs (Version 3.1). The SDK is based entirely off the name-value pair API, but performs the core payment activities (such as error handling/parsing, network communication, and data encoding) behind the scenes. Providing the end developer with this allows the developer to start integrating immediately without having to write out a mass of boiler plate code.

• Ruby 1.8.7 or higher

• Nokogiri 1.4.3 or higher

• RubyGem 1.3.7 or higher (to build the gem)

• RDoc 1.0 or higher (to build documentation)

• Rake 0.8.7 or higher (to use the rake tasks)

Goto the Authorize.Net SDK download page and download the Ruby gem. Then

> gem install authorize-net-1.5.1.gem

require 'rubygems'
require 'authorize_net'

transaction = AuthorizeNet::AIM::Transaction.new('API_LOGIN', 'API_KEY', :gateway => :sandbox)
credit_card = AuthorizeNet::CreditCard.new('4111111111111111', '1120')
response = transaction.purchase('10.00', credit_card)

if response.success?
  puts "Successfully made a purchase (authorization code: #{response.authorization_code})"
else
  raise "Failed to make purchase."
end

A generator is provided to aid in setting up a Direct Post Method application. In the example below payments is the name of the controller to generate.

> sudo gem install rails -v '~> 2.1'
> rails my_direct_post_app
> cd my_direct_post_app
> script/generate authorize_net_direct_post payments YOUR_API_LOGIN_ID YOUR_TRANSACTION_KEY MERCH_HASH_KEY
> script/server

After running the generator you will probably want to customize the payment form found in app/views/payments/payment.erb and the receipt found in app/views/payments/receipt.erb.

There is also a default layout generated, app/views/layouts/authorize_net.erb. If you already have your own layout, you can delete that file and the reference to it in the controller (app/controllers/payments_controller.rb).

A generator is provided to aid in setting up a Server Integration Method application. In the example below payments is the name of the controller to generate.

> sudo gem install rails -v '~> 2.1'
> rails my_sim_app
> cd my_sim_app
> script/generate authorize_net_sim payments YOUR_API_LOGIN_ID YOUR_TRANSACTION_KEY MERCH_HASH_KEY
> script/server

After running the generator you will probably want to customize the payment page found in app/views/payments/payment.erb and the thank you page found in app/views/payments/thank_you.erb.

You may also want to customize the actual payment form and receipt pages. That can be done by making the necessary changes to the AuthorizeNet::SIM::Transaction object (@sim_transaction) found in the payment action in app/controllers/payments_controller.rb. The styling of those hosted pages are controlled by the AuthorizeNet::SIM::HostedReceiptPage and AuthorizeNet::SIM::HostedPaymentForm objects (which are passed to the AuthorizeNet::SIM::Transaction).

There is also a default layout generated, app/views/layouts/authorize_net.erb. If you already have your own layout, you can delete that file and the reference to it in the controller (app/controllers/payments_controller.rb).

require 'rubygems'
require 'authorize_net'

transaction = AuthorizeNet::ARB::Transaction.new('API_LOGIN', 'API_KEY', :gateway => :sandbox)
subscription = AuthorizeNet::ARB::Subscription.new(
  :name => "Monthly Gift Basket",
  :length => 1,
  :unit => :month,
  :start_date => Date.today,
  :total_occurrences => :unlimited,
  :amount => 100.00,
  :invoice_number => '1234567',
  :description => "John Doe's Monthly Gift Basket",
  :credit_card => AuthorizeNet::CreditCard.new('4111111111111111', '1120'),
  :billing_address => AuthorizeNet::Address.new(:first_name => 'John', :last_name => 'Doe')
)
response = transaction.create(subscription)

if response.success?
  puts "Successfully created a subscription (subscription id: #{response.subscription_id})"
else
  raise "Failed to create a subscription."
end

require 'rubygems'
require 'authorize_net'

transaction = AuthorizeNet::AIM::Transaction.new('API_LOGIN', 'API_KEY', :gateway => :card_present_sandbox)
credit_card = AuthorizeNet::CreditCard.new(nil, nil, :track_1 => '%B4111111111111111^DOE/JOHN^1803101000000000020000831000000?')
response = transaction.purchase('10.00', credit_card)

if response.success?
  puts "Successfully made a purchase (authorization code: #{response.authorization_code})"
else
  raise "Failed to make purchase."
end

For your reference, you can use the following test credit card numbers. The expiration date must be set to the present date or later. Use 123 for the CCV code.
