U-M Shibboleth Identity Provider (InCommon) is one of 7 APIs that [University of Michigan-Ann Arbor](https://apis.io/providers/university-of-michigan-ann-arbor/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, Shibboleth, InCommon, and SSO. The published artifact set on APIs.io includes API documentation, authentication docs, and code examples.

The University of Michigan's own Shibboleth SAML 2.0 identity provider, and the most unambiguously institution-operated machine-readable surface U-M publishes. GET https://shibboleth.umich.edu/idp/shibboleth returns 200 application/xml (10,923 bytes) — an IDPSSODescriptor with protocolSupportEnumeration urn:oasis:names:tc:SAML:2.0:protocol, signing and encryption key descriptors, SSO and SLO endpoints, and shibmd:Scope entries for umich.edu, annarbor.umich.edu, umd.umich.edu, dearborn.umich.edu and flint.umich.edu. Registered in InCommon and therefore reachable through eduGAIN. U-M ITS Identity and Access Management publishes working SAML and OIDC service-provider integration examples publicly at github.com/umich-iam. This is federation metadata, not a REST API — there is no OpenAPI to write and none has been invented.
