Yp::Ruby

Ruby Class bindings for the Yorkshire Payments Direct HTTP Integration API

Add this line to your application's Gemfile:

gem 'yp-ruby'

And then execute:

$ bundle

Or install it yourself as:

$ gem install yp-ruby

Different classes are available for the Gateway actions:

• Yp::Sale
• Yp::Preauth
• Yp::Verify

If you need support for more actions, please open an issue!

You will need to pass in the correct parameters according to the Yorkshire Payments integration guide:

signature_key = 'Engine0Milk12Next'

params = {
  merchantID: '101381',
  countryCode: 826,
  currencyCode:  826,
  cardNumber:  '4012001037141112',
  cardExpiryMonth:  12,
  cardExpiryYear:  15,
  cardCVV:  '083',
  customerName:  'Yorkshire Payments',
  customerEmail:  'support@yorkshirepayments.com',
  customerAddress:  '16 Test Street',
  customerPostCode:  'TE15 5ST',
  orderRef:  'Test purchase'
}

transaction = Yp::Sale.new(signature, params)

The library will not validate your parameters before sending. This feature is coming soon.

You pass in a callback method as a block, or access the response after the transaction is sent:

transaction.send! do |response|
  puts response.state # --> 'captured'
end

# OR:

response = transaction.send!
puts response.state # --> 'captured'

The client will raise a number of different types of errors:

These occur if we could not perform any validation. This means the response is malformed and can arise if you did not correctly sign your request:

• Yp::Response::InvalidSignatureError (potentially malicious)
• Yp::Response::MissingSignatureError
• Yp::Response::MissingResponseCodeError

These occur if, during validation, we found a Gateway error code. These come in three different flavours:

• Yp::Response::MissingFieldError: a field was missing in your request
• Yp::Response::InvalidFieldError: a field value was invalid in your request
• Yp::Response::GatewayError: the error could not be classified. The gateway's error message will be supplied

This occurs if the transaction has entered the Declined state:

• Yp::Response::DeclinedError

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
