APIs are the language systems use to communicate. A website with a mobile app, a CRM with an e-commerce platform, or payments with accounting all depend on APIs. Well-designed APIs improve flexibility and scalability; poor design creates long-term constraints.

FAQ
Which is better — REST or GraphQL?
REST is simpler to implement and fits most projects. GraphQL gives clients more flexibility and is useful for complex data models. The right choice depends on your product requirements.
Do I need API documentation?
Yes, especially when API consumers include other teams or partners. Swagger/OpenAPI documentation significantly reduces integration and maintenance overhead.
How can API access be secured?
Use OAuth 2.0, JWT, or API keys, enforce HTTPS, add rate limiting, rotate secrets, and monitor logs. Include security requirements in your task.
Can Finnish public services be integrated via API?
Yes. Services such as Suomi.fi, DVV, and Traficom provide public interfaces. Mention the target service to match specialists with relevant integration experience.
Is this suitable for API-based business automation?
Yes. CRM sync, accounting exports, logistics integration, and event-driven workflows are typical automation use cases.
