API Types - INI
API Types is a classification of web API architectural styles and protocols widely used in modern software development, including REST, GraphQL, SOAP, gRPC, and WebSocket. Each type corresponds to different communication patterns, data formats, and use cases, forming the foundation for data exchange between systems. The choice of appropriate API type significantly impacts system performance, scalability, and development efficiency.
