The Confirmation Node allows you to prompt the user for a Yes or No answer.  It helps when you want to verify information or allow the user to make a choice.

For example, in Book Flight Bot, you can use a confirmation node to prompt the user to respond if they would like to know the weather forecast at the destination.

The confirmation node’s conditional transitions go beyond the If-Else expressions. The transition depends on user reply: assertion (yes) or negation (no). The Else condition comes into play if their answer isn’t both.

Add the Node

Setting up a confirmation node in a dialog task involves the following steps:

1. Open the dialog task to which you want to add the Confirmation node.
2. Add a Confirmation node in the designated place. For steps related to adding nodes, refer here.
3. The Confirmation window is displayed with the Component Properties tab selected by default.

Configure the Node

Component Properties

Notes:  The configurations you set up or edit in these sections reflect in all other dialog tasks that use this node.  This article works with the new dialog builder, you will find this feature in legacy builder at the same location i.e. Confirmation node -> Component Properties.

 

To configure the component properties, follow the below steps:

1. On the Component Properties tab, under the General Settings section, enter a Name and a Display Name.
2. Under the User Prompts section, you can compose the confirmation request either as plain text or as a JavaScript message.You can enter channel-specific messages for User Prompts using the Manage link. For more information, refer to Using the Prompt Editor.
   1. To add more prompts , click Add a Prompt and repeat the above steps.
   2. Enable the channel-specific standard formatting to Display Confirmation Options
      If this is not enabled, the yes/no options will not be displayed to the end-user.
   3. Platform detection of Yes/No is based on the below keywords. The platform ensures that the yes/no synonyms, including the internal ones, are processed at the same time and the earliest choice is taken. This means that something like of course not is considered as NO, and is not mapped  to YES because of course could also be part of the YES synonym. Also, the yes/no synonyms are concepts and patterns as well.
      
      For yes:

So, many of these words are only treated as a yes or no if they appear at the start or the end of an utterance, not in the middle.
3. You can use Rephrase Responses to rewrite VA replies using AI based on conversation context and user emotions. For Confirmation nodes, this feature helps rephrase the responses entered under User Prompts. To see this feature in your node’s Component Properties, please first enable the OpenAI or Azure-OpenAI integration and the Dynamic Prompt and Message Rephrasing feature under LLM and Generative AI.  This feature is disabled by default for each node. Turn on the toggle to enable Rephrase Responses.

   You can configure the number of previous user inputs to determine how many previous user messages should be sent to OpenAI as context based on which to rephrase the response sent through the node. You can choose between 0 and 5, where 0 means that no previous input is considered, while 5 means that the previous 5 responses are sent as context.
    

4. You can also add context-specific Synonyms for Yes and No within the Confirmation node to suit the dialog’s context. The Platform can identify the emojis in user utterance and consider them for confirmation/rejection, for example, a thumbs-up emoji will be taken to mean confirmation from the user.
   
   

   Note: The Platform now supports additional Synonyms for Traditional Chinese language for Yes/No confirmation. Learn more.
5. In the Variable Namespaces section, associate the variable namespaces to execute this node and its transitions. This option is visible only when the Variable Namespace is enabled for the assistant you are working with. You can go with the task level settings or customize it for this node. For more information, refer to Managing Namespace.
   

Additional Synonyms for Traditional Chinese Language

For the Traditional Chinese language, the Platform provides the following additional synonyms for “yes” and “no” responses on the Confirmation node:

Yes Confirmation

"係", "係呀", "講得啱", "啱", "冇問題"

No Confirmation

"唔係", "冇", "無", "唔得", "唔可以", "唔使", "唔要", "唔想", "唔啱"

These synonyms can be configured on the confirmation node under Component Properties > Synonyms during the Build stage of a Dialog Task.

After detecting these additional synonyms, the Confirmation node extracts “yes” or “no” from the user utterance.

Instance Properties

1. On the Confirmation Component Properties window, click the Instance Properties tab.
2. Under the Interruptions Behavior section, you can configure the interruptions behavior for this node.
   Note: The settings in the Instance Properties tab are specific to the current task and do not reflect in other dialog tasks that use this node.
   1. Use the task level ‘Interruptions Behavior’ setting: The VA refers to the Interruptions Behavior settings set at the dialog task level.
   2. Customize for this node option: You can customize the Interruptions Behavior settings for this node by selecting this option and configuring it. Refer to Interruption Handling and Context Switching article for more information.
3. Under the Precedence section, when the user’s input for an entity consists of a valid value for the entity and another intent, you can control the experience by choosing between Intent over Entity or Entity over Intent options. For example, if a Flight Booking assistant prompts for the destination and the user enters, Bangalore, how’s the weather there? you can define how the bot responds in such cases; pick the entity and add the intent to the follow-up intents stack or go ahead with the intent first based upon the Interruptions Behavior settings.
   
4. Under the Custom Tags section, add tags to build custom profiles of your VA conversations. Click here for more.
   

IVR Properties

You can use this tab to define the input mode, grammar, prompts, and call behavior parameters for this node to use in the IVR Channel. This is done at the node level. Click here for details.

Connections Properties

The Confirmation node’s conditional transitions go beyond the If-Else expressions used for the other nodes. You can define conditional expression based on a context object value, else a user assertion (yes), or else user negation (no). Beyond the three, you can define a fallback Else condition to trigger. 

Note: These conditions are applicable only for this instance and will not affect the node when being used in any other dialog.

For details on how to work with connection conditions, please see Adding IF-Else Conditions to Node Connections.
