OpenAPI

Last modified: 10 August 2022

Required plugin: OpenAPI Specifications (bundled)

An OpenAPI Specification (OAS) is a description format for REST APIs. Swagger is a set of tools based on this specification for writing, documenting, and consuming REST APIs. For more information, see Swagger documentation.

IntelliJ IDEA provides coding assistance for OpenAPI definitions in YAML and JSON files, and integration with Swagger Codegen for generating server stubs, client libraries (SDKs), and documentation based on your OpenAPI specification.
