Unified Identity Authentication (CAS / SSO)
ZJU's unified identity authentication platform — a Central Authentication Service (CAS) single sign-on login fronting campus systems. It supports username/password, QR-code scanning and third-party hand-off (DingTalk, QQ, WeChat, and Azure/Microsoft for the international campus). Interactive web login only: no service-registration endpoint, no published API contract and no developer documentation are reachable unauthenticated. Recorded as an institution-operated surface, not as a consumable API.
Not an API. Zhejiang University publishes no API for this. It is a product area, listed for completeness, and it is not counted in the provider's API total.
