API Development

Well-architected REST and GraphQL APIs that power your applications, connect your systems, and scale with your business demands.

OVERVIEW

APIs That Power Modern Digital Experiences

APIs are the backbone of every modern application. They connect your mobile app to your backend, your frontend to your database, and your systems to third-party services. Poorly designed APIs lead to slow applications, security breaches, and expensive rewrites. Well-designed APIs accelerate development, enable integrations, and scale effortlessly.

Gosotek builds APIs that follow industry best practices — clean resource design, proper authentication, comprehensive documentation, and thoughtful versioning. Whether you need a RESTful API for a mobile app, a GraphQL API for a complex frontend, or a microservices architecture to replace a monolith, we design and develop APIs that your team and your partners will love working with.

WHAT'S INCLUDED

Complete API Development Services

RESTful API Design

Clean, predictable resource-based APIs following REST conventions — proper HTTP methods, status codes, pagination, filtering, and HATEOAS links for discoverability.

GraphQL APIs

Flexible query-based APIs that let clients request exactly the data they need — reducing over-fetching, improving mobile performance, and simplifying complex data relationships.

Authentication & Security

OAuth 2.0 flows, JWT tokens, API key management, role-based access control, and input validation — every endpoint secured against unauthorized access and injection attacks.

Rate Limiting

Protect your API from abuse with configurable rate limits per user, per endpoint, or per API key. Graceful throttling with proper headers so clients can self-regulate.

API Documentation

Interactive Swagger/OpenAPI documentation with request/response examples, authentication guides, and a sandbox environment where developers can test endpoints live.

Versioning Strategy

Forward-compatible API versioning that lets you evolve your API without breaking existing consumers. URL or header-based versioning with clear deprecation policies.

OUR PROCESS

How We Build Your API

01

Design & Specification

We define resources, endpoints, data schemas, and authentication flows in an OpenAPI specification. You review the API contract before any code is written — design-first approach.

02

Development & Testing

We implement the API with clean architecture, write comprehensive unit and integration tests, set up CI/CD pipelines, and generate interactive documentation automatically.

03

Deploy & Monitor

Deploy to production with monitoring, logging, and alerting in place. We track response times, error rates, and usage patterns — and provide ongoing support and optimization.

WHY GOSOTEK

Why Choose Us for API Development

Design-First Approach

We design the API contract before writing code. This ensures consistency, enables parallel development, and catches issues before they become expensive to fix.

Production-Grade Quality

Comprehensive test coverage, proper error handling, logging, monitoring, and documentation — our APIs are built for production from day one, not as prototypes.

High Performance

Optimized query patterns, response caching, connection pooling, and async processing — our APIs handle thousands of requests per second without breaking a sweat.

Developer-Friendly Docs

Interactive documentation with code samples, sandbox testing, and clear guides. Your developers and partners will integrate with your API quickly and confidently.
