How can I aggregate an account from an authoritative application (creating identity cube as well) using SCIM API? Which SCIM endpoint should I use? Can anyone share any example?
This will depend on which SCIM endpoints are exposed/supported by your authoritative application. Typically, you want to aggregate from an endpoint that provides a list of user accounts along with the account attributes that are needed to build the identity cubes (first name, last name, email, manager, etc.). You would create a new Application definition in IdentityIQ using the SCIM Connector. Please refer to the SCIM Connector Guide: https://community.sailpoint.com/t5/IdentityIQ-Connectors/8-2-System-for-Cross-Domain-Identity-Management-2-0-Connector/ta-p/202784
