Choose yourintegration method

The only official standard across the Yunjii ecosystem (UM / Open Platform / family products) is OAuth 2.1 + OIDC. REST / QR / SDK / iframe are flexible options on top of the standard, all converging to one identity backend.

UM product & ecosystem

UM is a product-service core ecosystem, integrating via Yunjii API and marketed via the open platform.

Two ways to integrate — pick by scenario

Both reach Yunjii API; the only difference is whether you register an app first — standard for production, lite for quick tests.

Standard · OAuth 2.1★ Recommended

Registered app · full auth

The standard interface of the Yunjii ecosystem. Plug in with Auth.js / Spring etc. — no SDK needed, stable long-term.

Lite · One address

Keyless direct · paste & go

Capability-domain routing: /user is the unified identity capability (powered by standard OAuth 2.1), consistent with /market and /models. No multi-domain juggling, no protocol trivia — paste the discovery URL and go.

GET https://api.yunjii.cn/.well-known/openid-configuration
