Documenting REST APIs with OpenAPI and Swagger
Generate interactive, always-up-to-date documentation for your Spring REST APIs using the OpenAPI standard and Swagger UI.
Why Document Your API?
An API is only useful if consumers understand it. Good documentation describes endpoints, parameters, request bodies, and responses so other teams can integrate without guessing.
The OpenAPI Standard
OpenAPI is a vendor-neutral specification for describing REST APIs in a machine-readable format. Tools can read it to generate docs, client SDKs, and test suites.
