# Yale API Portal — Portal APIs

**Canonical:** https://apis.io/apis/yale/portal/  
**Provider:** Yale University — https://apis.io/providers/yale/  
**Base URL:** https://gw.its.yale.edu/soa-gateway  
**Documentation:** https://developers.yale.edu/api-documentation/portal-apis

Yale API Portal — Portal APIs is one of 13 APIs that [Yale University](https://apis.io/providers/yale/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Course Catalog, Buildings, Campus, and Gated. The published artifact set on APIs.io includes API documentation.

Yale's institution-operated developer portal documents four Portal APIs — Buildings (name and location of Yale campus buildings), Courses, Course Subjects and GatewayServiceMetrics. Yale's own page calls these INTERNAL APIs: a key is issued only after registering an application in the Developer Portal, and portal access requires a valid Yale NetID. The gateway is live — an anonymous call to the Courses Web Service v3 returned HTTP 400 with the body "Invalid API Key" — but no operation here is publicly callable, so no contract is claimed for it.
