The cancel order prebuilt component checks a user's authentication level. Once the user has been authenticated, the component provides information about the user's most recent or past orders. The user may then choose to cancel an entire order or cancel specific items in an order. This component uses the Retail authentication prebuilt component to authenticate users. The component also uses Generators for post-call summarization.
Limitations
In addition to the common prebuilt component limitations, this prebuilt component has the following limitations:
- This component does not encrypt any data.
Sample dialogs
The following sample dialogs demonstrate common scenarios handled by this prebuilt component. The sample dialogs demonstrate behavior when the component is called using telephony, which triggers the Default Welcome Intent and the first agent response at the start of the conversation.
Cancel single product in recent order
End-user has been previously authenticated. The agent confirms which items from the most recent order should be cancelled. The agent checks the original method of payment and confirms the cancellation details with the user.
