The Finalist 9.1 release introduced a new API called PBFNTransact (PBFNTRAN). Previously, to process a single address, an application would have to make three calls to Finalist - PBFNInit, PBFNProcess, and PBFNTerminate. PBFNTransact combines all three calls into a single call. The PBFNTransact API accepts two or three parameters - the SetupDef, and AddressData or SetupDef, and input AddressData, and output AddressData. The API is designed for quick processing of single addresses. PBFNTransact does not generate reports, uses minimal memory (storage), and is ideal for online types of applications.
