Hypermedia APIs & HATEOAS — Complete Guide

This tutorial series explores Hypermedia as the Engine of Application State (HATEOAS), the most advanced REST constraint. You'll learn the Richardson Maturity Model Level 3, hypermedia links with rel and href attributes, action definitions, link formats including HAL, JSON API, and Siren, dynamic API discovery, media types like application/hal+json, building HATEOAS clients, Design Patterns, the Temple payload pattern, partial representations, comparisons with Graphql, tools and frameworks including Spring HATEOAS, and a complete HATEOAS project. Hypermedia enables self-descriptive, evolvable APIs that clients can navigate without prior knowledge of endpoints.
