API Integrations

Systems Connected Securely

Design, build, and maintain APIs and integrations that move data between your products and third-party platforms with reliability and clear documentation.

Overview

Integration Layer Your Stack Can Trust

Modern businesses run on dozens of tools. APIs are the glue — when built well, they keep data flowing; when built poorly, they become your biggest support burden.

We design REST and GraphQL APIs, webhook handlers, ETL jobs, and iPaaS configurations with versioning, authentication, rate limiting, and observability from day one.

Whether exposing your product to partners or consuming external services, we deliver OpenAPI documentation and error handling patterns your developers can rely on.

Integration Services

API Development

  • REST & GraphQL Versioned endpoints, pagination, filtering, and consistent error response formats.
  • Authentication OAuth 2.0, API keys, JWT, and mutual TLS for partner and internal consumers.
  • Documentation OpenAPI/Swagger specs, Postman collections, and developer portals for partners.

Third-Party Integrations

  • SaaS connectors Payment, shipping, marketing, accounting, and HR platforms connected to your core app.
  • Webhooks Inbound event handlers with signature verification, idempotency, and retry logic.
  • Legacy adapters API facades in front of older systems to unlock modern integrations without full rewrites.

Middleware & Sync

  • Message queues Kafka, RabbitMQ, and cloud queues for decoupled, resilient data propagation.
  • ETL pipelines Scheduled and event-driven sync jobs with transformation and validation.
  • iPaaS setup MuleSoft, Boomi, or Make/Zapier for faster integrations when custom code is not required.

Operations

  • Rate limiting Protect upstream systems and enforce fair usage across API consumers.
  • Monitoring Latency, error rate, and payload logging with alerts on integration failures.
  • Testing Contract tests and sandbox environments so releases do not break partners.

API Integration FAQ

REST or GraphQL for our API?

REST remains the default for most B2B integrations and public APIs. GraphQL suits complex client-driven queries and mobile apps that need flexible data fetching.

Can you fix failing integrations we already have?

Yes. We diagnose timeout issues, schema drift, auth failures, and missing retries — then harden or rebuild integrations with proper monitoring.
