# API Development & Integration

We design and build a new API for your product or data – with OpenAPI, authentication and versioning

Modern companies need flexible, secure, and performant APIs to connect different systems, services, and applications. We develop RESTful and GraphQL APIs that meet the highest standards in security, documentation, and performance – including CI/CD pipelines, full observability, and OWASP-compliant security. From API architecture through implementation to documentation, versioning, and typed client SDKs – we ensure your APIs work reliably, are easy to integrate, and are future-proof.

## Perfect For



A fit if you want to open your own product or data to the outside: a SaaS application customers connect to via API, a mobile app that needs a backend, or data partners should be able to retrieve. It is about a new interface, not about connecting finished tools.

## Benefits



- RESTful & GraphQL API design and implementation

- Comprehensive API documentation (OpenAPI/Swagger) with Developer Portal

- OWASP API Top 10 compliant security (OAuth 2.0, JWT, Secrets Management)

- Rate limiting, DDoS protection, and API Gateway integration

- Observability: Distributed tracing, logging, metrics, and error budgets (SLOs)

- CI/CD pipeline with automated tests and contract testing (OpenAPI/Prism)

- Typed client SDKs and mock/sandbox environment for developers

- Backward-compatibility policy and semantic versioning

## How we work on it

- Sprint — 4 weeks · fixed price after scoping: Four weeks on one goal, with something that runs at the end.
- Build & Support — after scoping, ongoing · fixed price after scoping; support billed monthly: We build the project out and stay alongside you once it is live.

### Included

- API design with an OpenAPI specification before the first line of code
- Authentication and permission model (e.g. OAuth 2.0, API keys)
- Implementation with versioning and rate limiting
- Automated tests and deployment to your environment
- Developer documentation and handover to your team

### Not included

- Rebuilding the connected third-party systems themselves
- Frontend or app development (separately after scoping)
- Ongoing operations after the 30 days of bug fixing (optional via Build & Support)

### How it runs

- **W1 — Scoping & API design**: We clarify use cases, data model and consumers and capture the interface contract as an OpenAPI specification.
- **W2-3 — Implementation & tests**: Endpoints, authentication and error handling are built with automated tests; you see progress weekly in a staging environment.
- **W4 — Deployment & handover**: Go-live, documentation and handover to your team; followed by 30 days of bug fixing or further development in Build & Support.
