The ultimate test of any core banking project is not just the initial go-live, but its long-term viability.
How do you deliver a deeply customized, scalable core banking integration without creating a “code fork” that becomes a maintenance nightmare? The answer lies in a single-codebase architecture (1). Our project exemplifies a truly scalable core banking integration, delivering specific client needs while preserving universal upgradeability.
The Challenge: Customization vs. Upgradability
The institution required specific behaviors for authentication, UI embedding, and accounting. Traditionally, this would mean writing custom code, which fragments the product and makes future updates costly and complex. We needed a path to a scalable core banking integration that avoided this technical debt.
The Solution: An Intelligent Integration Layer
We achieved this by centralizing all client-specific logic in a powerful integration layer. This layer acted as a smart mediator, handling:
- API Routing: Directing requests to the correct external or internal systems.
- Data Transformation: Mapping fields and formats between different data schemas.
- Transaction Safety: Managing rollbacks using “compensate APIs” if external processes fail.
Consequently, Fimple’s core product code remained pure and untouched. The same version that served this client is deployed universally for all others.
Why This Matters for Your Future
This approach is the hallmark of scalable core banking integration. It means that when Fimple releases a new feature or security patch, every client—including this institution—benefits instantly. There is no costly re-integration project. This future-proofs your technology investment, allowing you to innovate faster with a platform that evolves with you.
