  title: Yahoo (formerly AOL) OAuth 2.0 and OpenID Connect OAuth2 API
  description: 'Yahoo OAuth 2.0 and OpenID Connect endpoints used by developers building on

    the Yahoo / former AOL identity platform. Following AOL''s acquisition by

    Verizon and merger with Yahoo, AOL developer identity APIs have been

    consolidated into the Yahoo Developer Network. The OAuth 2.0 Authorization

    Code grant is the supported flow; OpenID Connect adds a userinfo endpoint

    and a JWKS endpoint exposed at api.login.yahoo.com.


    This specification is generated from the public Yahoo Developer Network

    OAuth 2.0 / OpenID Connect documentation and the OpenID Connect discovery

    document at https://login.yahoo.com/.well-known/openid-configuration.
