Hi All,

Here the code of Automated Recurring Billing (ARB) in ruby.

First install the active_merchant plugins in your application.

// ruby code 

  require 'rubygems'
  require 'active_merchant'

    def payment
        ActiveMerchant::Billing::Base.mode = :test
        amount = 10       
        credit_card = ActiveMerchant::Billing::CreditCard.new(
              :first_name         => 'dinesh',
              :last_name          => 'singh',
              :number             => '4242424242424242',
              :month              => '12',
              :year               => '2020',
              :verification_value => '123'
            )
       
         if credit_card.valid?       
       
        gateway = ActiveMerchant::Billing::AuthorizeNetGateway.new(
                :login => 'username',
                :password => 'password'
              )

        # Authorize for the amount
        response = gateway.recurring( amount, credit_card,         
           {  :interval =>{:length=>1, :unit =>:months},
              :duration => {:start_date=>'2010-01-01', :occurrences=>1},
              :billing_address=>{:first_name=>'dinesh', :last_name=>'singh'}
           }
         )
       
        #response = gateway.purchase(amount, credit_card)
       
        if response.success?
          puts response.params.inspect
          puts "Successfully charged $#{sprintf("%.2f", amount / 100)} to the credit card #{credit_card.display_number}. The Account number is #{response.params['rbAccountId']}"
        else
          puts response.message
        end
      end        

     end
     
  hope this will be helpful for all
