                         maximum_fraud_score => 500,
                         preCharge_id => '1000000000000001',
                         preCharge_security1 => 'abcdef0123',
                         preCharge_security2 => '3210fedcba',
                        )
  my $transaction = new Business::OnlinePayment($processor, %processor_info);
  $transaction->content(
                        type       => 'Visa',
                        amount     => '49.95',
                        cardnumber => '1234123412341238',
                        expiration => '0100',
                        name       => 'John Q Doe',
                       );
  $transaction->submit();
  if($transaction->is_success()) {
    print "Card processed successfully: ".$transaction->authorization()."\n";
  } else {
    print "Card was rejected: ".$transaction->error_message()."\n";
  }

Overview

This is a module that adds functionality to Business::OnlinePayment. See Business::OnlinePayment.

The user instantiates a Business::OnlinePayment object per usual, adding in three processor directives

•

fraud_detection

Which Fraud Detection module to use.

•

maximum_fraud_score

FraudDetection drivers are expected to return a numeric "risk" factor, this parameter allows you to set the threshold to reject the transaction based on that risk. Higher numbers are "riskier" transactions.

•

other driver-specific parameters.

Consult the specific Fraud Detection module you intend to use for its required parameters.

The $tx->submit() method is overridden to interpose a FraudDetection phase. A subordinate object is created using the same content as the parent OnlinePayment object, and a Fraud Detect action is run against that subordinate object. If the resulting fraud score is less than or equal to the maximum_risk parameter, the parent transaction will be allowed to proceed. Otherwise, a failure state will exist with a suitable error message.

Methods

This module provides no new methods. It does, however override the submit method to interpose an additional Fraud Detection phase.
