                       );
  $transaction->submit();

  }
```

## DESCRIPTION

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.
