Which API architectures does Dev House Austria support?

We build RESTful APIs, GraphQL APIs, WebSocket APIs, and event-driven architectures using message brokers such as Kafka or RabbitMQ. We select the optimal approach based on your performance requirements, data model, and integration landscape.

How does your team secure APIs in production?

We apply industry-standard security controls including OAuth 2.0 and JWT authentication, enforced HTTPS, rate limiting, input validation, and scheduled security audits to protect your APIs against OWASP Top 10 vulnerabilities and emerging threats.

Will we receive full API documentation?

Yes. Every API we deliver includes comprehensive documentation built on OpenAPI/Swagger standards, interactive testing consoles, and integration guides so your teams and partners can consume the API efficiently from day one.

Can you integrate APIs with legacy systems?

Absolutely. We have extensive experience connecting modern APIs with legacy platforms, cloud-native services, third-party SaaS tools, and mobile applications, ensuring a smooth fit within your existing IT landscape.

Scope

API Development Services We Deliver

RESTful API Development

We engineer standards-compliant RESTful APIs optimised for throughput, reliability, and developer experience, enabling your applications to exchange data consistently across platforms, devices, and geographies.

GraphQL API Development

Our team builds GraphQL APIs that let clients request exactly the data they need in a single call, eliminating over-fetching and dramatically improving performance for complex, data-intensive front-ends.

Third-Party API Integration

We connect your platform with payment providers, CRM tools, logistics services, and SaaS products across the DACH ecosystem, extending functionality without redundant development effort.

API Security & Authentication

We enforce OAuth 2.0, JWT-based auth, API key management, rate limiting, and strict input validation to shield your APIs from unauthorised access, injection attacks, and abuse at every endpoint.

API Documentation

We produce comprehensive, versioned API documentation following OpenAPI/Swagger specifications, giving your internal teams, partners, and external developers everything they need for rapid, error-free integration.

API Testing & QA

Our QA engineers execute functional, security, load, and regression test suites against every API surface to guarantee reliability, performance, and data integrity before production deployment.

APIs That Drive Real Business Value

From architecture through deployment and ongoing optimisation, our API specialists deliver connected systems that grow with your organisation.
