API Development & System Integration

Design, build, and operate the APIs and integrations that let your enterprise applications talk to each other — reliably and securely.

API & Integration

Connect Every System You Run

Modern enterprises run on integration. Pro Lens designs and delivers REST, GraphQL, and event-driven APIs, plus middleware and EAI that connect ERPs, CRMs, portals, and legacy systems into one coherent platform.

From API strategy and gateway design to legacy adapters and real-time event pipelines, we build integrations that are secure, observable, and built to last.

What We Offer

API & Integration Capabilities

REST & GraphQL API Design

Well-designed, documented, and versioned REST and GraphQL APIs — aligned with OpenAPI standards and built for developer experience.

System Integration Architecture

Enterprise integration patterns, architecture blueprints, and reference implementations that map cleanly to your application landscape.

Middleware & ESB

Middleware and enterprise service bus implementations using modern platforms — routing, transformation, and orchestration across systems.

Legacy System Integration

Adapters, wrappers, and facades that bring mainframe and legacy applications into a modern API-driven architecture without a full rewrite.

API Gateway & Management

API gateway setup, rate limiting, authentication, developer portals, and full API lifecycle management for governance and control.

Event-Driven Integration

Kafka, message queues, and event-streaming pipelines that enable real-time, decoupled communication between enterprise systems.

Why Choose Pro Lens for API & Integration
Why Pro Lens

Why Choose Us for API & Integration

API-First Approach

We design APIs as products — contracts first, with clear versioning, documentation, and developer experience at the core.

Vendor-Neutral Architecture

We pick the right integration stack for your landscape — not the one that maximises a vendor's license revenue.

Security & Governance Built-In

OAuth2, mTLS, quotas, audit logs, and gateway policies applied by default — not bolted on later.

Monitoring-Ready Delivery

Every integration ships with logging, metrics, and tracing hooks so operations can see what's happening from day one.
