The RADIO framework provides a strong foundation for designing APIs and system integrations with consistency and maintainability in mind

  System Integrations & API Design: The RADIO Framework The RADIO framework provides a consistent, maintainable, and scalable approach to designing APIs and system integrations. It stands for Resource-oriented, Addressable, Documentable, Idempotent, and Observable. Resource-Oriented (R) Principle Focus on nouns (resources) over verbs (actions). 1. Aspect Implementation Detail Maintainability/Consistency Impact API Endpoints Use nouns in the URI (e.g., /users, /products/{id}). Employ standard HTTP methods (GET, POST, PUT, DELETE, PATCH) for CRUD operations. Predictability: Developers easily infer endpoint purpose. Clarity: Leverages standard REST principles, separating the what (resource) from the how (action). Data Models Define stable, versioned schemas (JSON/XML) for resource representations that reflect the resource's state. Decoupling: Protects consumers from internal system changes by maintaining a stable external API contract. 2. Addressable (A) Principle Every resource ...
