API development

Build secure, scalable, and well-documented APIs that power modern applications and enable seamless system integration

Overview

APIs (Application Programming Interfaces) are the backbone of modern digital ecosystems. They enable applications to communicate, share data, and orchestrate business processes across platforms, services, and organizations. Well-designed APIs accelerate development, improve user experiences, and unlock new business models.

Our API development expertise spans the full API lifecycle, from design and development to security, documentation, versioning, and monitoring. We build RESTful APIs, GraphQL services, real-time WebSocket connections, and serverless APIs that are performant, secure, and developer-friendly.

A well-designed API in action

Request

GET/api/v1/customers/1042

Response

—
Clear resources, correct status codes and predictable errors: reads are cacheable, creates return the new location, and throttled clients are told exactly when to retry.
Explore the guide
Six focused deep dives, from choosing the right API style to running your APIs reliably in production.
Styles & technology
REST, GraphQL, gRPC, real-time and OData compared, and the frameworks we build them with.
Explore
Design principles
Resource naming, HTTP methods, status codes, error formats, pagination and filtering done consistently.
Explore
Security & identity
OAuth 2.0 and Entra ID, managed identities, role and claims-based authorization, and the essential safeguards.
Explore
Performance & scale
Caching at every layer, efficient data access, compression and horizontal scaling.
Explore
Documentation & versioning
OpenAPI contracts, documentation developers enjoy, and versions that evolve without breaking clients.
Explore
Testing & monitoring
The testing pyramid, contract and load tests, Application Insights, structured logging and health checks.

API development best practices
Design principles
  • Design for the consumer, not the implementation
  • Keep APIs simple and focused on single responsibility
  • Use consistent naming conventions and patterns
  • Plan for versioning from day one
  • Document as you build, not as an afterthought
Performance & reliability
  • Implement caching at multiple layers
  • Use async/await for I/O operations
  • Apply rate limiting and throttling
  • Design for idempotency (safe retries)
  • Implement circuit breakers for external dependencies
Security & compliance
  • Enforce HTTPS and strong TLS versions
  • Validate and sanitize all inputs
  • Use OAuth 2.0 for authentication
  • Implement proper authorization checks
  • Audit sensitive operations and data access
Our API development approach
We build APIs that are secure, performant, and developer-friendly. Our approach ensures APIs become strategic assets that enable innovation and growth.
API-first design
Design OpenAPI specification first, gather stakeholder feedback, then implement. Ensures consistency and alignment.
Security by default
Build security into every layer: authentication, authorization, input validation, encryption, audit logging.
Developer experience
Comprehensive documentation, SDKs, code samples, sandboxes, and responsive support for API consumers.
Production excellence
Monitoring, alerting, CI/CD pipelines, automated testing, and robust error handling for reliable operations.
