Reference Intents in the Dialog Flow

You can reference intents directly from the dialog flow.

For dialog flows designed in Visual mode you define intent events in the Main Flow. see Map an Intent to a Flow.

For dialogs designed in YAML mode, you configure intents as action transitions for the System.Intent component to navigate to appropriate state for the resolved intent. For example, here's what the System.Intent might like if you had intents called OrderPizza and CancelPizza:
  intent:
    component: "System.Intent"
    properties:
      variable: "iResult"
    transitions:
      actions:
        OrderPizza: "startOrder"
        CancelPizza: "cancelorder"
        unresolvedIntent: "unresolved"
