Summary
Andrew (a veteran software architect) shares his API First design methodology rooted in object-oriented thinking: design the interface (API spec) before implementation, using OOP concepts to model the domain and then translate class interfaces into REST API endpoints. He argues that API spec quality accounts for 70%+ of an API’s success, and that combining a few deeply-mastered fundamentals (OOP, state machines, auth/authz) gives architects combinatorial problem-solving power.
Andrew 分享以物件導向思維為基礎的 API First 設計方法：在實作前先設計介面（API 規格），用 OOP 概念建模領域，再將類別介面翻譯成 REST API 端點。他認為 API 規格品質占 API 成功的 70% 以上，並強調精通少數基礎技能（OOP、狀態機、認證授權）的組合運用能力。
Key Points
- API spec quality determines 70%+ of API success — implementation quality is secondary
- API First = Interface First: design objects/classes/interfaces in OOP, then translate to API spec
- OOP mapping: class → resource, constructor → POST/PUT (create), getter/setter → GET/PATCH, methods → actions
- State machine thinking: model resource lifecycle states, then design APIs around state transitions
- Mastering a few fundamentals deeply gives more problem-solving range than knowing many shallowly

Insights
The OOP-to-API translation framework is a practical bridge for engineers comfortable with object-oriented design. The key insight is that API design is not a different discipline from OOP — it’s the same interface design problem, just expressed over HTTP. The emphasis on state machines for resources is particularly useful: most poorly-designed APIs fail because they don’t think about state transitions and end up with inconsistent, unpredictable behavior.

Raw Excerpt
API 的成功與否，規格定的好不好 (這是設計議題) 占了 70% 以上，規格定對了，後面的實做 (效能，可靠度等等) 做得好才有加分。
