About

OpenAPI is a specification language for defining HTTP APIs, typically written in YAML or JSON.

It enables automated generation of interactive documentation (via tools such as Swagger UI and Redoc), schema-based request and response validation, automatic creation of client SDKs and server stubs in multiple programming languages, and integration into CI/CD pipelines.

OpenID is a decentralized authentication protocol based on OAuth 2.0 that enables applications to verify a user's identity through an external identity provider instead of managing credentials directly.

It adds an identity layer on top of OAuth by issuing ID tokens that confirm who the user is, supports single sign-on across multiple services, and allows retrieval of basic profile information.
