Customizing the Universal Bot’s Default Dialog Task

Universal bots come with a built-in dialog task that triggers automatically for unidentified intents. You can customize this dialog task, or import another, but cannot replace it with other standard responses. You can add more nodes to the default dialog task to build a custom experience

Default Dialog Task

Before you Begin

This article assumes that you understand the fundamentals of creating dialog tasks using the Bots Platform and therefore focuses on the aspects specific to the universal bots. To refer to the fundamentals of dialog tasks, read Dialog Tasks.

Default Dialog Nodes

Nodes that can be added to universal bot are limited compared to the standard bots. Below is the list of nodes that can be added to the default dialog task in the universal bot:

  • Send a message
  • Ask a question
  • Ask for an entity
  • Make a service call
  • Run a JavaScript
  • Initiate Agent Transfer
  • Enable WebHook connections

Customize the Default Dialog

Follow these steps to customize the default dialog message:

  1. Open the universal bot for which you want to configure new channels.
  2. Hover over the left navigation panel and click Natural Language -> Default Conversation.
  3. On the Natural Language window, click Default Dialog.
  4. Listed will be the default dialog – Intent Not Identified.
  5. Click to open the dialog. You will see an Intent and Message node already configured.
  6. You can customize the default dialog like any other dialog task adding the above-mentioned nodes.

Customizing the Default Dialog for an Enabled Language

If the NLP engine cannot recognize the user intent, the universal bot responds to the users with the default dialog. You must create language-specific versions of the default dialog for each enabled language so that such bot responses go in the users’ preferred language. Otherwise, the universal bot responds applies the default bot language regardless of the user’s preferred language. Learn more.

Event Handlers

Before you Begin

This article assumes that you understand the fundamentals of Event Handler functionality using the Bots Platform and therefore focuses on the aspects specific to the universal bots. To refer to the fundamentals of Event Handling, read Event Based Bot Actions.

With the release of ver8.0 of the platform, the ‘Events’ in the Universal Bot support triggering of the Dialog Tasks from the linked bots. For events that support the execution of tasks, you can choose the linked bot and a task from the linked bot.

The linked task will be executed at the trigger of the event. If the linked bot task is not available at the run time or in the language that the end-user is having the conversation in, then the end-user would be presented with the relevant Standard Response ‘Dialog task required for conversation is not available’

Variable Management

While building Universal bots you might want to propagate few values to the linked bots, like:

  • the environment details, when building multi-lingual bots, while migrating the universal bot from one environment to another.
  • the tenant values for scoping the bot intents.

Before you Begin

This article assumes that you understand the fundamentals of creating variables using the Bots Platform and therefore focuses on the aspects specific to the universal bots. To refer to the fundamentals of variable management, read Using Bot Variables.

Variable Declaration

As with Standard bots, you can

  • Define Global and Content variables.
  • Enable the propagation of the variable value to a selected linked bot.
  • You can access these variables in the script using {{env.<variable-name}} and {{content.<variable-name>>}}
  • In case the variable name is defined in both linked and universal bot, Universal bot variable value would take precedence.
