RESTful APIs

Representational State Transfer (REST) is an architectural style for designing networked applications. RESTful APIs use HTTP methods to perform CRUD operations and communicate between client and server using stateless, cacheable requests with standard conventions. This collection covers RESTful API design principles, best practices, standards, tools, and the OpenAPI Specification ecosystem.

RESTful APIs is profiled on the APIs.io network. Tagged areas include Architecture, HTTP, REST, Web Services, and OpenAPI.

The RESTful APIs catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
