B2B Backend Partnership
Powering a client-owned B2B dashboard with a dedicated proxy backend
A B2B operator had its own dashboard, customer relationships, and commercial model. It needed a backend partner that could expose reliable proxy operations through APIs without taking ownership of the product experience.

The challenge
The client-facing product already reflected a mature B2B sales and support process. Replacing that interface would have disrupted customer workflows, yet extending the existing proxy backend to support new supply types and markets was slowing every product decision.
The integration needed to divide ownership without creating an operational gap. The client dashboard had to remain responsible for accounts, billing presentation, and customer communication, while the proxy backend needed authority over routing, limits, usage, and availability.
A loose integration would have produced conflicting records. Both systems therefore needed explicit identifiers, idempotent provisioning, lifecycle events, and enough telemetry for each team to diagnose incidents from its own operational surface.
Previous setup
Integration before the dedicated backend
Customer dashboard coupled to infrastructure-specific operations
New proxy categories required new provisioning paths
Billing records and network usage reconciled by batch jobs
Failures lacked shared request and account identifiers
Infrastructure changes competed with frontend roadmap work
Responsibility during incidents crossed team boundaries
Architecture after ProxyRequest
Network engine
Multi-protocol supply
Routing and load distribution
Quota and connection enforcement
Health monitoring and failover
Integration contract
Idempotent provisioning API
Shared account identifiers
Lifecycle and usage events
Traceable request metadata
Client application
Owned dashboard and brand
Customer and payment workflows
Business reporting
Support communication
The API boundary represents product intent rather than infrastructure commands. The client application requests a package, region, and lifecycle state; ProxyRequest resolves the network implementation and publishes attributable events back to the client’s business systems.
Before / After
| Before | After |
|---|---|
| Dashboard called infrastructure-specific actions | Stable product-oriented API contract |
| Each proxy category had a separate workflow | One lifecycle across product types |
| Usage reconciled in periodic batches | Attributable usage events and records |
| Failures investigated across disconnected logs | Shared identifiers across both systems |
| Infrastructure work blocked customer features | Backend and dashboard roadmaps decoupled |
| Incident ownership changed by symptom | Explicit operational responsibility at the API boundary |
Outcomes
The existing product experience remained intact. Customers kept familiar account, billing, and support workflows while the backend changed underneath.
New supply became an integration concern, not a frontend project. Additional network capabilities fit the same product API.
Both teams gained a shared operational language. Account, request, and lifecycle identifiers made incidents traceable across the boundary.
Responsibilities became scalable. The client team could focus on customers and commercial workflows while ProxyRequest maintained network behavior.
