UT Austin Enterprise Identity Provider (SAML 2.0 + OpenID Connect) is one of 5 APIs that [University of Texas at Austin](https://apis.io/providers/university-of-texas-at-austin/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, Shibboleth, SAML, OpenID Connect, and InCommon. The published artifact set on APIs.io includes authentication docs and API documentation.

UT Austin's Shibboleth identity provider, and the most under-catalogued class of institutional API surface. It publishes SAML 2.0 metadata at /idp/shibboleth (entityID https://enterprise.login.utexas.edu/idp/shibboleth) with HTTP-POST, POST-SimpleSign, HTTP-Redirect and SOAP/ECP bindings, and the same entity resolves signed from the InCommon metadata query service, confirming InCommon/eduGAIN participation. It also serves a full OpenID Connect discovery document at /.well-known/openid-configuration advertising authorization, token, userinfo, JWKS, introspection, revocation, end-session and dynamic client registration endpoints, and ten scopes — six of them institution-defined (utexas_profile, utexas_restrict, utexas_student_extended, memberof, groups, iidasmail). Both documents are anonymously readable and machine-readable; obtaining client credentials is an institutional process, not self-service. Verified live (HTTP 200) on 2026-08-30.
