# Yale University Identity Federation Metadata

**Canonical:** https://apis.io/apis/yale/identity-federation/  
**Provider:** Yale University — https://apis.io/providers/yale/  
**Base URL:** https://auth.yale.edu  
**Documentation:** https://its.yale.edu/

Yale University Identity Federation Metadata is one of 13 APIs that [Yale University](https://apis.io/providers/yale/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Identity Federation, SAML, Shibboleth, and InCommon. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Yale operates a Shibboleth Identity Provider at auth.yale.edu and publishes a signed SAML 2.0 EntityDescriptor for entityID https://auth.yale.edu/idp/shibboleth, unauthenticated, declaring OrganizationName "Yale University", shibmd:Scope "yale.edu" and SingleSignOnService endpoints for the Shibboleth 1.0, SAML 1.1 and SAML 2.0 profiles. The same entity is registered in InCommon (registrationAuthority https://incommon.org) and retrievable from InCommon's per-entity metadata query service, which carries it into eduGAIN. The host resolves inside Yale's own AWS identity estate. This is not a REST API and was never meant to be one — it is catalogued because it is a verified, machine-readable, unambiguously institution-operated surface, and it is the artifact universities publish most consistently and catalog least often.
