Overview
The thinking behind it
Banking environments are notoriously fragmented: Oracle FLEXCUBE, OBDX, payment switches, CBS adapters, and dozens of third-party integrations all require careful orchestration. The Finexta API Gateway provides a single, hardened control plane for managing this complexity. Built from real implementation experience, it handles authentication, rate limiting, transformation, routing, and observability out of the box.
Product specifications
Applications
Where it gets used
Core banking modernisation
Expose FLEXCUBE services to digital channels without modifying the core — the gateway handles versioning, throttling, and format translation.
Open banking compliance
Publish PSD2 and equivalent APIs with regulatory-grade security controls enforced at the gateway, not scattered across upstream services.
Third-party ecosystem
Onboard fintech partners and data aggregators with controlled API access, SLA enforcement, and usage analytics.
Why it matters
What you gain
Faster integration cycles
Pre-built connectors cut typical integration work from weeks to days. Teams iterate on business logic, not plumbing.
Reduced operational risk
A single security enforcement point eliminates the inconsistencies that occur when 20 services each implement their own auth.
Visibility across the stack
Real-time dashboards and audit trails give operations and compliance teams the data they need without bespoke tooling.
Client voices
What our clients say
Finexta's team brought deep Oracle expertise and a real commitment to our go-live deadline. The OBDX implementation was smooth and the post-production support has been outstanding.
What set Finexta apart was their ability to bridge business requirements and technical delivery. Our FLEXCUBE migration completed on schedule with zero critical post-go-live incidents.
The 24/7 managed services team is responsive and proactive. We've seen measurable improvement in system uptime and our internal team now focuses on innovation rather than firefighting.
