Hands-On RESTful API Design Patterns and Best Practices

Good REST API design is more than choosing endpoint names. It involves making resources, interactions, representations, versioning, and security work together coherently. Hands-On RESTful API Design Patterns and Best Practices by Harihara Subramanian and Pethuru Raj explores those decisions, moving from REST fundamentals to patterns and operational concerns for APIs used in modern services.

Start with the architecture, then shape the interface

The book lays out the foundations of REST and resource-oriented design before turning to the practical choices that define an API: URI structure, HTTP methods and status codes, headers, media types, message bodies, and error representations. Its design guidance also considers consistency, reusability, flexibility, and how clients discover and use resources.

Patterns for everyday API decisions

Coverage of essential patterns includes statelessness, content negotiation, URI templates, pagination, discoverability, and error handling. The discussion then advances to versioning, authorization, idempotency, bulk operations, circuit breakers, API facades, and backend-for-frontend approaches. Together, these topics give readers a vocabulary for comparing design options rather than treating every endpoint as a one-off decision.

Microservices, testing, and security

Further sections examine API gateways in microservice environments, including service discovery, composition, monitoring, scaling, and resilience. The book also addresses API testing and security, with topics such as authentication, authorization, common vulnerabilities, and penetration testing.

For developers and architects working with APIs

This technical guide is aimed at web, mobile, and cloud-services developers, architects, and consultants who want to design and maintain well-structured RESTful APIs. Its progression from architectural principles to patterns, gateways, testing, and security makes it useful for readers who want to connect interface design with the wider demands of dependable services.
