If you have the SSO URL for an application that is not in the Application Catalog, you can connect to the application without using SAML. Typically, the application already exists in your organization, but it may be an application from a service provider (SP) if the SP supplies you the URL for the application.
You can then make the application available to your single sign-on (SSO) users.
Note: Applications you’ve made available using the SSO URL cannot be added to the
authentication context in the PingOne authentication policy. However, if the SSO
URL references an application configured for SSO in PingFederate, you can apply
multi-factor authentication in PingFederate using a PingID advanced policy.
