APIs that power your product ecosystem.
An API is the foundation of a modern software product. Whether you're building a mobile app that talks to a backend, integrating your platform with third-party services, or exposing your data to partners, the quality of your API determines the velocity of every team that builds on top of it.
Techifive designs and builds production-ready REST and GraphQL APIs using Node.js and Python, with comprehensive documentation generated via OpenAPI 3.0 and published in developer portals. We implement OAuth 2.0 and JWT authentication, role-based access control, rate limiting, and request signing — security patterns that protect both your platform and your API consumers.
Third-party integration is where API projects most often go wrong: poorly handled webhooks, missing retry logic, and no error recovery cause silent data loss. We build integrations with resilient patterns: idempotent webhook processors with signature verification, exponential backoff retry mechanisms, dead-letter queues, and reconciliation jobs that catch and correct discrepancies between systems.
Auto-generated, interactive API documentation that developers can use to explore and test endpoints without reading source code.
API versioning strategy ensures existing integrations never break when you add new capabilities.
Signature-verified, idempotent webhook handlers with retry queuing and dead-letter recovery for zero data loss.
Per-client rate limiting with graceful degradation prevents any single consumer from impacting service availability for others.
Resource modelling, endpoint specification in OpenAPI, and review with your consuming teams before implementation begins.
Authentication scheme selection, authorisation model, rate limiting configuration, and penetration test scope definition.
API development with test coverage for every endpoint, integration with your database and external services.
Interactive API docs, integration guides, code samples in multiple languages, and optional client SDK generation.
k6 load test to target RPS, fix any performance bottlenecks, then staged production rollout.
