API Development & Integrations

APIs that connect your business

Modern businesses run on integrations. We design and build REST APIs that are clean, versioned, well-documented, and secure — and we integrate any third-party platform your business depends on, no matter how awkward the API.

API design and development

• RESTful API design with OpenAPI / Swagger documentation
• Django REST Framework endpoints with serialisers, viewsets, and nested routers
• Flask API microservices with async support
• Authentication — JWT, OAuth2, API key management, and session-based auth
• Rate limiting, throttling, and pagination for high-traffic endpoints
• Webhook receivers and outbound webhook dispatchers with retry logic

Third-party integrations we have shipped

• EDI (X12) — electronic data interchange with logistics and supply-chain partners
• Google Maps API — GEO coverage calculations, ZIP code routing, coverage map generation
• Transactional email — Mailgun integration with bounce handling and deliverability monitoring
• Live chat — Livechat API for support ticket creation and conversation sync
• Mapping and logistics — carrier coverage, freight routing, and address validation
• Payment gateways — Stripe, PayPal, and custom processor integrations

Reliability and observability

Third-party APIs go down, rate-limit you, and change their schemas without warning. We build integration layers with retry queues (SQS or Celery), idempotency keys, dead-letter queues, and Sentry alerting — so your system degrades gracefully instead of silently breaking.
