Using Application ID with the Login and ssoLogin Operations
Important:
Starting with the 2020.2 SOAP web services endpoint, request-level credentials are no longer supported for authentication. The Passport complex type isn't supported. Attempting to use request-level credentials in 2020.2 and later endpoints will result in an error and the request won't be processed. For 2020.2 and later endpoints, ensure your SOAP web services integrations use TBA. User credential authentication is still supported in 2020.1 and earlier endpoints. For more information, see Token-based Authentication and Web Services.
