.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a module that adds functionality to Business::OnlinePayment.  See Business::OnlinePayment.
.PP
The user instantiates a Business::OnlinePayment object per usual, adding in three processor directives
.IP "\(bu" 4
fraud_detection
.Sp
Which Fraud Detection module to use.
.IP "\(bu" 4
maximum_fraud_score
.Sp
FraudDetection drivers are expected to return a numeric \*(L"risk\*(R" factor, this parameter allows you to set the threshold to reject the transaction based on that risk.  Higher numbers are \*(L"riskier\*(R" transactions.
.IP "\(bu" 4
other driver-specific parameters.
.Sp
Consult the specific Fraud Detection module you intend to use for its required parameters.
.PP
The \f(CW$tx\fR\->\fIsubmit()\fR method is overridden to interpose a FraudDetection phase.  A subordinate object is created using the same content as the parent OnlinePayment object, and a \fIFraud Detect\fR 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.
.SH "METHODS"
.IX Header "METHODS"
This module provides no new methods.  It does, however override the
submit method to interpose an additional Fraud Detection phase.
