Class: OffsitePayments::Integrations::FirstData::Notification

Inherits:
AuthorizeNetSim::Notification show all
Defined in:
lib/offsite_payments/integrations/first_data.rb

Overview

First Data payment pages emulates the Authorize.Net SIM API. See OffsitePayments::Integrations::FirstData::Notification for more details.

Example:

parser = FirstData::Notification.new(request.raw_post) passed = parser.complete?

order = Order.find_by_order_number(parser.invoice_num)

unless order @message = 'Error--unable to find your transaction! Please contact us directly.' return render :partial => 'first_data_payment_response' end

if order.total != parser.gross.to_f logger.error "First Data said they paid for #parserparser.gross and it should have been #orderorder.total!" passed = false end

Theoretically, First Data will never pass us the same transaction

ID twice, but we can double check that... by using

parser.transaction_id, and checking against previous orders' transaction

id's (which you can save when the order is completed)....

unless parser.acknowledge FIRST_DATA_TRANSACTION_KEY, FIRST_DATA_RESPONSE_KEY passed = false logger.error "ALERT POSSIBLE FRAUD ATTEMPT" end

unless parser.cavv_matches? and parser.avs_code_matches? logger.error 'Warning--non matching CC!' + params.inspect

Could fail them here, as well (recommended)...

end

if passed

Set up your session, and render something that will redirect them to

your site, most likely.

else

Render failure or redirect them to your site where you will render failure

end
