Platform Migration
Guide clients through CPaaS migrations without emergency redevelopment — their existing integrations keep working while you move the infrastructure beneath them.
Master API Wrapper
Nexus Flow
Nexus Flow
Nexus Flow sits between your clients' existing software and a new messaging platform, acting as a silent translation layer. When your platform migrates or is deprecated, their API calls are intercepted, translated, and passed on — so critical business systems keep working without a single line of code changed. Your customers stay, their workflows stay intact, and your migration is invisible to them.
Where it fits
Use Cases
Nexus Flow keeps migration projects commercially safe by protecting customer integrations, routing logic, and mission-critical messaging workflows while the underlying platform changes.
Critical Workflow Protection
Keep life-critical communications running in utilities, healthcare, and emergency services during platform transitions where downtime is simply not an option.
Multi-Region Routing
Apply complex routing logic — such as directing Australian traffic to one platform and all other traffic to another — without touching a single line of client code.
Legacy System Continuity
Let clients keep their existing credentials, API calls, and business logic intact while you modernise the messaging infrastructure beneath them at your own pace.
How it works
Features
Built to sit in the middle without getting in the way, Nexus Flow gives you the routing, translation, and cutover controls needed to move platforms without forcing customers to rebuild.
Silent Translation
Intercepts existing API calls and translates them to the new platform format — invisibly and in real time, with no disruption to the client experience.
Master Router
A central routing engine that directs traffic based on fully configurable rules — geography, account type, message content, or any custom logic you define.
Modular Adapters
Swappable, platform-specific adapters mean you can add new destination platforms without rebuilding the core system — extend as your portfolio grows.
Configuration Store
Manage all routing rules and client mappings in one place — no code deployments needed when rules change. Update and apply in real time.
Credential Passthrough
Clients authenticate with their existing credentials. The Wrapper handles translation to new platform authentication transparently behind the scenes.
Zero-Downtime Cutover
Clients simply point their software to a new endpoint. Their calls, workflows, and integrations continue without interruption — migration becomes a non-event.
