# NTHU Academic Information System OAuth 2.0 Service

**Canonical:** https://apis.io/apis/nthu/nthu-oauth-api/  
**Provider:** National Tsing Hua University — https://apis.io/providers/nthu/

**Documentation:** https://oauth.ccxp.nthu.edu.tw/v1.1/doc/

NTHU Academic Information System OAuth 2.0 Service is one of 4 APIs that [National Tsing Hua University](https://apis.io/providers/nthu/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Identity and Authentication. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, authentication docs, and a support channel.

The one API National Tsing Hua University operates itself. An OAuth 2.0 authorization-code service run by the Computer and Communication Center on NTHU's own host, letting a reviewed external application authenticate an NTHU faculty, staff or student account against the Academic Information System (CCXP) and read an approved subset of six identity fields — userid, name, email, inschool, cid and lmsid. NTHU publishes the interface manual itself; the OpenAPI here is derived from that manual, not fabricated, and all three endpoints were probed live on 2026-08-30. Access is application-gated: a unit head must sign, the Computer and Communication Center must review, and each data-owning unit must approve the fields released. Secret keys expire after one year.
