API & Systems Integration

Who this is for

Businesses struggling with isolated data silos or needing automated synchronization between internal systems and third-party platforms.

Problems we help with

• Employees manually copying data between CRM, accounting software, and operational databases
• Dropped webhook events or duplicate data writes causing billing or inventory chaos
• Inability to connect modern web applications to legacy on-premise databases
• Lack of observability when third-party APIs fail or experience downtime

What you receive

• Idempotent API middleware service with automatic retry queues and dead-letter storage
• Rate-limiting and request throttling protecting backend services from overload
• Comprehensive OpenAPI / Swagger contract documentation
• Centralized logging dashboard with real-time alerting on integration failures
• Zero-downtime deployment setup via Docker containers

How it works

1. 1

   Endpoint & Schema Discovery

   Analyzing API documentation, authentication schemes (OAuth2, API keys, mTLS), and data mapping requirements.

2. 2

   Middleware Architecture

   Engineering transform pipelines, error handlers, and message queuing (Redis / RabbitMQ).

3. 3

   Simulated Integration Testing

   Mocking endpoint outages, rate-limit responses, and payload schema changes to verify resilience.

4. 4

   Live Deployment

   Staged rollout with dual-write validation before decommissioning manual synchronization.

Scope and exclusions

• Access credentials to third-party vendor APIs must be provided by the client
• Third-party API subscription fees are the responsibility of the client
