Designing a defensible consent logging architecture for BFSI systems
Choose a central consent ledger and integration pattern Implement a central consent service or ledger that exposes APIs to all channels and systems, and acts as the source of truth for consent state. Use event streaming or webhooks so downstream systems stay in sync without tight coupling. Prefer append-only, immutable events over in-place updates, with clear status transitions. Integrate the ledger with your ESB or event bus to propagate updates to core banking, LOS, CRM, and data lakes.
