Fraud screening interface

The fraud screening interface implements the integration points for the system that hosts the fraud screening services of the bank.

FTM for High Value Payments defines an ISF format for the Fraud Screening Request and Fraud Screening Response messages that are used to interface with the fraud screening service. The default mapper implementation passes these ISF messages as-is. The supplied simulator is compatible with the ISF messages only. It is expected that customer-specific mappers are most likely needed to integrate with the real fraud screening service of the bank.

The fraud screening interface supports the following operations:

Table 1. Fraud screening interface
Operation	Direction	Description	Format
Fraud Screening Request	Out	Request for a fraud screening check.	ISF CreditTransfer
Fraud Screening Response	In	Response indicating fraud risk is acceptable.	ISF Acknowledgment
Fraud Screening Reject Response	In	Response indicating fraud risk is not acceptable.	ISF Acknowledgment
Fraud Screening Pending Response	In	Response indicating the fraud screening is delayed and a final result is expected later.	ISF Acknowledgment

By default, the fraud screening interface is implemented using two logical FTM channels, each using an IBM® MQ transport.

Correlation is configured on the FTM Fraud Screening Provider service participant as Correlate with UID of request transmission (IN_TXN_ACK_MQ2) At the IBM MQ level, FTM for High Value Payments sends a common ID on MsgId and CorrelId and the service must reply with either value on the CorrelId in the response.
