4 API Architectural Styles You Should Know

REST, webhooks, gRPC, and HATEOAS each serve distinct API design needs. REST offers simple, stateless, cacheable interactions ideal for standard web services and CRUD operations. Webhooks enable real-time, event-driven communication without polling, perfect for automation and reactive applications. gRPC provides high-performance, low-latency communication using HTTP/2 and Protobuf, supporting multiple streaming patterns for microservices. HATEOAS enables dynamic discoverability through hypermedia links, offering flexibility and potential for AI agent integration. The choice depends on specific requirements like real-time events, performance needs, or dynamic navigation capabilities.
