VU Amsterdam SAML 2.0 identity provider (SURFconext / eduGAIN) is one of 7 APIs that [Vrije Universiteit Amsterdam](https://apis.io/providers/vrije-universiteit-amsterdam/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, SSO, SURFconext, and eduGAIN. The published artifact set on APIs.io includes API documentation.

Vrije Universiteit Amsterdam operates its own SAML 2.0 identity provider on Microsoft ADFS and publishes signed, machine-readable federation metadata for it. entityID http://stsfed.login.vu.nl/adfs/services/trust; SingleSignOnService at https://stsfed.login.vu.nl/adfs/ls/; the metadata document carries both IDPSSODescriptor and SPSSODescriptor roles and supports SAML 2.0 alongside WS-Federation and WS-Trust. The same entity appears in the SURFconext national IdP feed with mdui:DisplayName "Vrije Universiteit Amsterdam" and shibmd:Scope vu.nl, from where SURFconext publishes it onward to eduGAIN. This is the surface a university operates by definition, it is genuinely first-party, and it was entirely absent from the June 2026 profile of this institution.
