Step-by-Step Integration Guide

1. Setting Up Your Ruby Environment

First, ensure you have Ruby installed on your system. You can download it from Ruby’s official website.

Next, install the necessary gems. You will need the authorize-net gem to interact with the Authorize.net API.

gem install authorize-net

2. Configure API Credentials

Create a configuration file to store your API credentials securely. For example, you can create a config.yml file:

api_login_id: “YOUR_API_LOGIN_ID”

transaction_key: “YOUR_TRANSACTION_KEY”

3. Initialize the Authorize.net Client

In your Ruby application, initialize the Authorize.net client using the credentials from your configuration file.

require ‘yaml’

require ‘authorizenet’

config = YAML.load_file(‘config.yml’)

api_login_id = config[‘api_login_id’]

transaction_key = config[‘transaction_key’]

transaction = AuthorizeNet::API::Transaction.new(api_login_id, transaction_key, :gateway => :sandbox)

4. Create a Payment Transaction

To process a payment, you need to create a transaction request. Here’s an example of how to create a credit card transaction:

request = AuthorizeNet::API::CreateTransactionRequest.new

request.transactionRequest = AuthorizeNet::API::TransactionRequestType.new()

request.transactionRequest.amount = 100 # Amount in USD

request.transactionRequest.payment = AuthorizeNet::API::PaymentType.new

request.transactionRequest.payment.creditCard = AuthorizeNet::API::CreditCardType.new(‘4111111111111111’, ‘1224’) # Dummy card for sandbox

response = transaction.create_transaction(request)

if response.messages.resultCode == AuthorizeNet::API::MessageTypeEnum::Ok

  puts “Transaction ID: #{response.transactionResponse.transId}”

else

  puts “Error: #{response.messages.messages[0].text}”

end

5. Handle the Response

It’s crucial to handle the response from Authorize.net appropriately. Check for success or error messages and take necessary actions.

if response.transactionResponse.errors != nil

  response.transactionResponse.errors.errors.each do |error|

    puts “Error Code: #{error.errorCode}”

    puts “Error Message: #{error.errorText}”

  end

else

  puts “Transaction Successful!”

end
