Application Connector Endpoints are auto-generated based on authorization vault entries you create for Cloud Connectors. See Selecting Cloud Connector authentication. This type of endpoint enables CIC to consume web services provided by a cloud application.
You cannot create, update, or delete Application Endpoints from the CIC Cockpit.
Any integration using this type of Endpoint is driven by the Integration Engine and CIC Studio. Application Connectors Endpoints are not available to be used in Data Flows in the CIC Cockpit. They are, however, used by CIC Cockpit to display Job information on the Job List page and the Job Details page.
