Reliance Jio Authentication
Reliance Jio's publicly documented authentication surface is entirely the JioMeet / JioEvents developer platform. Two distinct models are in play. Server-to-server (JioMeet Platform Server API, JioEvents Platform Server API) uses a self-signed JWT built from app credentials issued in the JioMeet console and sent in the Authorization header - the spec models it as a required header PARAMETER, not a securityScheme, so it is invisible to tooling that only reads components.securitySchemes. User-authorized access (JioMeet Platform OAuth API) is a real OAuth 2.0 authorization-code flow with HTTP Basic client authentication at the token endpoint and HTTP Bearer on every subsequent call - that surface IS modelled as securitySchemes. Jio's network / CAMARA APIs are not in scope here: they are partner-gated through Aduna and the GSMA federated hub, and Jio publishes no CIBA endpoint and no OIDC discovery document anywhere in its estate.
Reliance Jio secures its APIs with http, jwt-bearer, and oauth2 across 3 declared security schemes, as derived from its OpenAPI definitions. OAuth 2.0 is offered via the authorizationCode flow(s).
