One image plays every UI of the multi-ui sample (customer-portal, admin-portal, shop-site, ops-console): it shows the host it was reached on, and lets you call paths on that
same host. A UI with a gateway reaches its gateway's root_path (/shop/..., /manage/...): sign in first at /auth (a gateway answers a call that has no session with 401 and does not redirect); a gateway-less UI (auth: proxy, ops-console) reaches
its services at /api/<service>/... after the platform's sign-in proxy has logged the user in, with the access token attached.
Any path:
