Overview

First Data payment pages emulates the Authorize.Net SIM API. See ActiveMerchant::Billing::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 #{parser.gross} and it should have been #{order.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
