Create a page or section in your application for the customer's administrator. Then use the Customer Connection REST API to elicit the necessary SAML connection information (SAML attribute values) from the customer.
All PingOne resource requests require authentication. You need to include your REST API Client ID and REST API Client Secret credentials in the request, otherwise the resource returns a 401 (Unauthorized) status code. Currently, we support HTTP basic authentication, which includes encrypted credentials in the request header. See Using the global REST API client credentials for more information.
