What does API-first mean?
API-first means designing the system interface (API) before building the user interface. Instead of the API being an afterthought, it becomes the core of the architecture.
Advantages of API-first
Flexibility (same backend can drive website, mobile app, partner integration), parallel development, easier integration, and future-proofing.
When does API-first fit?
- You are building a product that should integrate with other systems
- You plan mobile app in addition to website
- You want to offer partners or customers API access
- You are building microservices instead of monolithic application
Best practices for API design
- RESTful principles – Consistent and predictable structure
- Versioning – Plan for future changes
- Documentation – Use OpenAPI/Swagger
- Authentication – OAuth 2.0 or API keys
- Rate limiting – Protect against overload
