Challenge
The primary challenge of this project was handling the highly complex and heterogeneous fraud resolution processes followed by thousands of banks. Each bank had different workflows, response formats, timelines, and technical maturity levels.
Additionally, the system needed to manage long-running fraud cases, asynchronous communication, secure data exchange, and large volumes of complaints without manual intervention. Coordinating and assisting multiple bank development teams to align with a single automated process was another major hurdle.
Our Solution
We built a centralized and scalable fraud automation platform using .NET Core Web APIs and Entity Framework Core. The system automatically registers fraud complaints and sends them to respective banks using scheduler-based background services.
Banks process the complaints and respond via dedicated response APIs. These responses are consumed, validated, and stored back into our database, allowing the automation cycle to continue until the fraud case is fully resolved.
Automated complaint registration and bank communication- Scheduler-driven API calls and background processing
- Secure and reliable data exchange with banks
- Scalable architecture supporting thousands of banks
- End-to-end automation until fraud resolution
- Robust logging, tracking, and audit support
The Solution
A generic and configurable API framework was designed so that all banks could integrate using a common logic. The scheduler fetches pending complaints from the database and automatically pushes them to banks based on defined rules and timelines.
Generic API contracts adaptable to all banks
Scheduler-based automation for zero manual intervention
Secure, scalable, and high-performance API architecture
The Impact
The system significantly reduced fraud resolution time by eliminating manual processes. Banks were onboarded faster, and complaint tracking became transparent and auditable.
Faster fraud resolution and improved efficiency
Seamless coordination across thousands of banks
Reliable audit trails and regulatory compliance
Conclusion
This project showcases how a carefully designed, generic fraud resolution API platform can handle complex, high-volume banking workflows at a national scale. By collaborating closely with banking teams and focusing on reliability, validation, and automation, we delivered a system that simplifies fraud case handling while meeting strict operational and compliance requirements.
Generic & Reusable APIs
Built a fully generic API layer that supports multiple banks, complaint categories, and fraud types—eliminating the need for bank-specific implementations and reducing long-term maintenance overhead.
Secure & Validated Workflows
Implemented strict request validation, authorization checks, and audit-ready workflows to ensure secure data exchange between banks and central fraud systems.
Operational Impact
Automated end-to-end fraud resolution, reduced manual processing time, and improved response speed—enabling banks to act faster and improve customer trust.
