Integrating to the existing systems of a bank

This section provides instructions on how to approach the integration tasks specific to the internal systems of the bank.

Integration of FTM for High Value Payments into the existing systems of a bank is different for each customer. It is expected that a bank integrating FTM for High Value Payments into their environment will use their existing systems for fraud, sanction and accounting. The general approach to this should be as follows:
  1. Identify a business level mapping between the defined operations of the High Value Payments interface and the existing service interface of the bank.
  2. For each operation, define a logical mapping specification from ISF to/from the external format for each operation.
  3. Implement an outbound mapper to implement the logical transformation from ISF to the external format to cover each operation.
  4. Implement inbound mappers to implement the logical transformation from the external format to ISF to cover each operation.
  5. Implement outbound mappers to implement the logical transformation from the ISF to external format to cover each operation.
  6. Include the new maps on the relevant wrapper flow artifacts in the IBM® App Connect Enterprise workspace.
  7. Enhance your standard High Value Payments model to redefine the FTM channel definitions used for the service interface to use the new mappers.

In the default configuration, many transaction types, and therefore ISF, may not be persisted to the database to improve performance. In the context of integration, if detailed samples of ISF documents are required, it is recommended to turn on ISF logging for all channels and run High Value Payments using the provided simulators and customer specific test data. FTM then captures all ISF documents, which can be reviewed for the individual mapper design,implementation, and testing.
