Available for B2B scenarios in Dynamics 365 Commerce (including headless Commerce), this feature enables retailers to configure unified sign-in in Commerce headquarters and integrate third‑party storefronts using CSU APIs. The organization selector and related capabilities are exposed via CSU endpoints so that third-party sites can consume identities, organizational context, and ordering workflows without relying on native UI components.
