Codnity Dev — API Integration & Microservices

API Integration Services & Microservices Architecture

Enterprise API development and microservices architecture connecting CRM, ERP, finance, and operational systems in real time. We eliminate data silos and build scalable distributed platforms.

Trusted by growing companies

Disconnected systems cost more than the integrations that fix them

Manual data transfers, fragile point-to-point connectors, and systems that can't share data in real time create operational drag that compounds with every new tool you add. The cost isn't just inefficiency — it's missed decisions.

⚠️

Data Lives in Silos

CRM, ERP, finance, and operational tools each hold a piece of the picture but never share it.

Manual Data Transfer Between Systems

Teams export, copy-paste, and reconcile data across platforms — wasting hours on work that should be automated.

Fragile Point-to-Point Integrations

Brittle custom connectors break when any system updates, creating downstream failures and data inconsistencies.

🔄

No Real-Time Synchronization

Batch processes and manual syncs mean decisions are made on stale data — sometimes hours or days behind reality.

🔒

Scaling Breaks Connections

As transaction volume grows, existing integrations degrade — timeouts, data loss, and cascading failures become routine.

What Our API Integration Services Include

We build complete integration architectures — from individual API endpoints to full microservices platforms. Every engagement is scoped to your systems landscape.

🔗

REST API Development

Custom RESTful API design and development with versioning, documentation, rate limiting, and authentication built in from day one.

  • RESTful endpoint design

  • OpenAPI / Swagger documentation
  • Rate limiting & throttling
  • OAuth2 & API key authentication
  • Pagination & filtering
🏗️

Enterprise System Integration (CRM + ERP + Finance)

Structured integration pipelines connecting Salesforce, HubSpot, SAP, NetSuite, Xero, QuickBooks, and other enterprise platforms into a unified data flow.

  • CRM system integration
  • ERP data synchronization
  • Financial platform connectivity
  • Bi-directional data sync
  • Conflict resolution logic
  • Multi-system orchestration
🧩

Microservices Architecture Design

Decomposing monolithic applications into independently deployable, scalable microservices with clear domain boundaries.

  • Domain-driven service decomposition
  • Service mesh configuration
  • Container orchestration (Kubernetes)
  • Service discovery & routing
  • Circuit breaker patterns
  • Independent deployment pipelines

Event-Driven Architecture

Real-time event streaming and message-based communication between services using Kafka, RabbitMQ, or cloud-native event buses.

  • Event sourcing patterns
  • Message queue implementation
  • Real-time data streaming
  • Pub/sub architecture
  • Dead letter queue handling
  • Event schema registry
🛡️

API Gateway & Security

Centralized API gateway configuration with authentication, authorization, monitoring, and traffic management across all services.

  • API gateway setup (Kong, AWS API Gateway)
  • JWT & OAuth2 implementation
  • Role-based access control
  • Request/response transformation
  • API analytics & monitoring
  • DDoS protection & IP whitelisting

How We Deliver

Every integration project follows a structured methodology designed to minimize risk, ensure data integrity, and deliver connected systems that scale.

Step 01

Systems Audit & Mapping

Comprehensive inventory of all systems, data flows, integration points, and current pain points across your technology stack.

Step 02

Integration Architecture

Architecture design defining API contracts, data models, event flows, security layers, and scalability requirements.

Step 03

API Development

Iterative development of APIs, microservices, and integration pipelines with continuous testing and documentation.

Step 04

Testing & Monitoring

Comprehensive integration testing, load testing, and monitoring setup to ensure reliability under production conditions.

Step 05

Deployment

Staged rollout with zero-downtime deployment, data migration, and system cutover coordination across all connected platforms.

Step 06

Ongoing Optimization

Performance tuning, new integration onboarding, API versioning, and proactive monitoring for continuous improvement.

What makes us different

Most integration work is reactive — connecting two systems when something breaks. We design integration architectures that anticipate growth, enforce data quality, and scale without re-engineering.

01

Systems-First Thinking

We start with a complete systems audit — mapping every data flow, dependency, and integration point before designing a single API.

02

Real-Time Architecture

Event-driven and streaming patterns ensure data moves between systems in real time, not through overnight batch jobs.

03

Security-First

Every API and integration is built with OAuth2, JWT, encryption at rest and in transit, and role-based access control from the start.

04

Scalable by Design

Microservices and API architectures designed to handle 10x growth without re-engineering the foundation.

05

Platform Agnostic

We integrate with any system — cloud, on-premise, legacy, or modern SaaS — without vendor lock-in.

06

Ongoing Monitoring

Built-in observability, alerting, and performance dashboards so you know the health of every integration at all times.

API Integration FAQ

Everything you need to know before starting an API integration or microservices project with Codnity Dev.

We integrate virtually any system — CRM platforms (Salesforce, HubSpot, Pipedrive), ERP systems (SAP, NetSuite, Odoo), financial tools (Xero, QuickBooks, Stripe), project management (ClickUp, Jira, Asana), and custom internal applications. If it has an API or database, we can connect it.

REST APIs use fixed endpoints with structured request/response patterns — ideal for most enterprise integrations. GraphQL provides flexible querying where clients request exactly the data they need — best for complex frontend applications with varied data requirements. We recommend the approach based on your specific use case and existing infrastructure.

Most integration projects take 4–12 weeks depending on the number of systems, data complexity, security requirements, and whether existing APIs are available. Simple two-system integrations can ship in 4–6 weeks. Complex multi-system architectures with event-driven patterns typically require 8–12 weeks.

Both. We build greenfield microservices architectures for new platforms and incrementally decompose monolithic applications into microservices using the strangler fig pattern. The approach depends on your current architecture, risk tolerance, and business timelines.

Security is built into every layer — OAuth2 and JWT for authentication, role-based access control for authorization, TLS encryption for data in transit, encryption at rest for sensitive data, API rate limiting to prevent abuse, and comprehensive audit logging. We follow OWASP API security best practices on every project.
