Parters that have multiple sites (services) will require their users to navigate between sites. The PRIVO platform must act as the pass-through when navigating between sites. The login widget will handle this pass-through. The target URI is passed in the redirect_uri parameter in the authorization URL used to invoke the login widget. The client_id is for the target site must also be used in the authorization URL.
