Persistent connections

Use a persistent connection channel to an external system to avoid the overhead of creating and destroying a connection for every message.

IBM® Safer Payments uses a persistent connection outgoing channel type inside the model in the form of external model components and the Forward to external system option within masterdata elements. Both of these can be used to enhance transaction scoring by using information that is retrieved from external systems. To not impose limits on these use cases, neither the external model component nor the masterdata perform special handling on encrypted attributes. The values of these attributes are always sent in clear-text.

This means that when an external model component or masterdata is set up to send sensitive data over a public network, the corresponding persistent connections must enable the Use SSL encryption option to protect the data transfer using certificates.
