OAuth 2.0 API

OAuth 2.0 is an HTTP-based framework that enables third-party applications to obtain limited and secure access to user-protected resources via access tokens—without exposing user credentials. It supports multiple authorization flows such as authorization code, client credentials, and device code across web, mobile, and server environments.
