Central Péage (CNPG) integration hub orchestrates bidirectional data flows between the badge toll system (PEABOC) and accounting system (SUPSPM). PEABOC transmits badge transactions, LIBER-T passages, and TIS toll data to CNPG, which acknowledges receipt and routes aggregated accounting entries—revenue, sales orders, billing discrepancies, and toll supplements—to SUPSPM. This hub-and-spoke topology ensures single-source-of-truth transaction processing and automated reconciliation across toll collection and financial reporting. Fork this diagram to customize integration flows, add new data sources, or document your toll system architecture. The pattern demonstrates enterprise data governance best practices for regulated transportation finance systems.
