What kind of editor can you use to manipulate integration flows?

In SAP Cloud Integration, integration flows are manipulated using a web-based graphical editor:

Allows drag-and-drop of adapters, mappings, scripts, and process steps.

Provides visual orchestration of message flows.

Command-line and raw code editors are not supported for iFlow design (though XML behind the iFlow exists, it is not directly edited by developers).

Thus, the editor is the Graphical editor.
