# UAB Central Authentication Service (CAS 3.0)

**Canonical:** https://apis.io/apis/uab/sso-cas/

**Base URL:** https://sso.uab.cat/cas/  
**Documentation:** https://sso.uab.cat/cas/login

UAB Central Authentication Service (CAS 3.0) is one of 11 APIs that [Autonomous University of Barcelona](https://apis.io/providers/uab/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Single Sign-On, Apereo CAS, and Authentication. The published artifact set on APIs.io includes authentication docs.

The CAS protocol face of the same server. https://sso.uab.cat/ redirects to /cas/login and the ticket-validation endpoint at /cas/p3/serviceValidate returns a well-formed cas:serviceResponse — an INVALID_TICKET authenticationFailure for a deliberately bad ticket, which evidences a live protocol endpoint and grants nothing. It is the authentication boundary for UAB's own applications, including the virtual campus at cv.uab.cat. Service registration is administrative; there is no self-service developer path and no published contract.
