API Design and Architecture

A good API is the backbone of any scalable architecture, a bad one the most expensive technical mistake. Under time pressure and without a concept, you end up with inconsistent endpoints, missing versioning, no documentation and an authentication that can't be extended. Every later change then becomes a risk.

We design and build REST and GraphQL APIs for longevity: clear endpoint structure, clean versioning, complete OpenAPI documentation, granular authentication and robust error handling. That way your interface stays maintainable even after years and grows with your requirements.

How we work

We start with a technical concept and the design of the endpoints, aligned with your business use cases. This is followed by the implementation with a versioning strategy and automated documentation. Before handover we set up authentication, rate limiting and monitoring and test the interface under real load conditions.

What you get

  • Technical concept and endpoint design
  • Implementation of the REST or GraphQL API
  • Automated OpenAPI documentation
  • Auth setup with OAuth2, API keys or JWT
  • Rate limiting and protection mechanisms
  • Monitoring and alerting
  • Complete handover documentation
