API Development FAQ

REST or GraphQL — which should I choose?+

REST for simple CRUD and public APIs. GraphQL for complex data requirements, mobile apps, or when clients need flexible queries. We'll recommend based on your use case.

Do you write API documentation?+

Yes — every API includes OpenAPI/Swagger documentation. For larger projects, we build interactive developer portals with code examples.

Can you add an API to our existing system?+

Yes — we build API layers on top of existing databases and systems, or extend existing APIs with new endpoints and features.

What about API security?+

All APIs include authentication (JWT/OAuth), rate limiting, input validation, and HTTPS. We follow OWASP API security guidelines.
