Installation

If using bundler, first add 'alpha_card' to your Gemfile:

gem 'alpha_card', '~> 0.4'

And run:

bundle install

Otherwise simply install the gem:

gem install alpha_card -v '0.4'

Dependencies required:

  • ruby >= 2.2.2 or jruby >= 9.0.5.0;

Configuration

In order to use Alpha Card Gateway API you need to have a Merchant account credentials such as username and password.

If your project will always use only one account for processing payments, then you can configure gem as follows:

AlphaCard::Account.username = 'username'
AlphaCard::Account.password = 'password'

In Rails applications you can create an initializer:

# config/initializers/alpha_card.rb
if Rails.env.test? || Rails.env.ci?
  AlphaCard::Account.use_demo_credentials!
else
  AlphaCard::Account.username = 'username'
  AlphaCard::Account.password = 'password'
end

Another way is to pass the credentials as a last argument when creating some transactions or perform operations (it can be useful when you need to operate with multiple Alpha Card accounts):

void = AlphaCard::Void.new(transaction_id: '312110')
void.process(username: 'demo', password: 'demo')

Example of usage

Create AlphaCard sale (pay for the order):

require 'alpha_card'

def create_payment
  # Setup merchant account credentials
  AlphaCard::Account.username = 'demo'
  AlphaCard::Account.password = 'password'

  billing = AlphaCard::Billing.new(email: 'test@example.com', phone: '+801311313111')
  shipping = AlphaCard::Shipping.new(address_1: '33 N str', city: 'New York', state: 'NY', zip_code: '132')

  order = AlphaCard::Order.new(id: 1, description: 'Test order', billing: billing, shipping: shipping)

  # Format of the amount: "XX.XX"
  sale = AlphaCard::Sale.new(card_expiration_date: '0117', card_number: '4111111111111111', amount: '1.50', cvv: '123')
  response = sale.create(order)
  #=> #<AlphaCard::Response:0x1a0fda ...>

  if response.success?
    puts "Order payed successfully: transaction ID = #{response.transaction_id}"
    true
  else
    puts "Error message: #{e.response.message}"
    puts "CVV response: #{e.response.cvv_response}"
    puts "AVS response: #{e.response.avs_response}"
    false
  end

  rescue AlphaCard::APIConnectionError => e
    puts "Connection problems: #{e.message}"
    false
end

Billing and Shipping is an optional parameters and can be not specified.

Note: take a look at the amount of the Order. It's format must be 'xx.xx'. All the information about variables formats can be found on Alpha Card Payment Gateway Integration Portal -> Direct Post API -> Documentation -> Transaction Variables

To simulate request that returns an error do the next:

  • to cause a declined message, pass an amount less than 1.00;
  • to trigger a fatal error message, pass an invalid card number;
  • to simulate an AVS match, pass 888 in the address1 field, 77777 for zip;
  • to simulate a CVV match, pass 999 in the cvv field.

AlphaCard Response

AlphaCard::Response contains all the necessary information about Alpha Card Gateway response. You can use the following API:

  • .text — textual response of the Alpha Card Gateway;
  • .message — response message be response code;
  • .transaction_id — payment gateway transaction ID;
  • .order_id — original order ID passed in the transaction request;
  • .code — numeric mapping of processor responses;
  • .auth_code — transaction authorization code;
  • .success?, .error?, .declined? — state of the request;
  • .cvv_response — CVV response message;
  • .avs_response — AVS response message.

Testing

It is recommended to mock Alpha Card gem functionality, but if you want to create a "real" specs, then you can use Alpha Card Services testing account:

AlphaCard::Account.use_demo_credentials!

Or you can pass the next credentials with any request: { username: 'demo', password: 'password' }
