The one piece of information needed from the user. For example, `Ask the user which service catalog item they need.`
|
|
Variable name

Name of the variable that stores the user response to this prompt. The variable name is automatically created from the **Node name** property.
|
|
Prompt
|
Prompt or question for the user. The prompt can be either a text string or a script that returns text. This value is used only when the default value is not specified. For example: `What's your name?`
You can create rich text to alter the styling of the prompt:
- Use single asterisks or underscores for italic text. For example, `*text*` or `_text_`.
- Use double asterisks or underscores for bold text. For example, `**text**` or `__text__`.
- Use triple asterisks or underscores for italic and bold text. For example, `***text***` or `___text___`.
- Use a spaced hyphen to add a bullet point to a line. For example, `- text`.
- Use a spaced right angle bracket to create a block quote. For example, `> text`.
- Use between one and six hash marks to create headers. For example, `#text#` or `######text######`
- Use brackets and parentheses to create a hyperlink. For example, `[Link text](url)`. Add an exclamation point to a hyperlink to display an image. For example, ``

NLU entity
|
Option to associate an NLU entity with the node. If an NLU entity is associated with the input variable for this node, Virtual Agent can slot-fill the specified value based on the user's utterance. Select an entity from the list of entities associated with the topic intent.
When you specify an entity for the node, the Do not ask users to confirm recognized entity toggle switch is displayed. When enabled, users are not prompted to confirm the extracted entity.
This field is available only when NLU discovery is enabled on the instance.

Default value
|
|
Default Value
|
Predefined value for the user response to the question or prompt. The response defined in the **Default value confirmation** field asks the user to confirm the default value. If the user responds with `no`, the value becomes null. The default value can be either a text string or a script that returns text. For example, if you're using dot-walking, the default value might be: `Script Variables > Last username`. Or if you're using a script, the default value might be: `{{vaScripts.lastUsername}}`.

Confirmation messages
|
|
Input completion confirmation
|
Bot response shown to the user when the node interaction is complete. The message can be either a text string or a script that returns text. For example, if you're using dot-walking: `Thanks, (Input Variables > Username)!` Or if you're using a script, the acknowledgement might be: `Thanks, {{vaInputs.username}}!`
|
|
Default value confirmation
|
Message that asks the user to verify that the value in the **Default value** field is correct. This message is used instead of a value in the **Prompt** field. It can contain either a text string or a script that returns text. For example, if you're using dot-walking: `Are you (Input Variables > Username)?` Or if you're using a script, the confirmation message might be: `Are you {{vaScripts.lastUsername}}?`.

|
|
Turn on to let users change the subject
|
Option to enable NLU prediction for this node. If enabled, users can enter text to answer questions, regardless of the type of input control being used. Virtual Agent uses this utterance to match another existing intent, letting the user switch topics.
|
|
Hide or skip this node
|
|
Conditionally show this node if
|
No-code condition statement or low-code script that specifies a condition for presenting this node in the conversation. The condition must evaluate to true.
|
|
Allow user to skip this node if
|
No-code condition statement or low-code script that specifies a condition for letting users skip this node in the conversation. The condition must evaluate to true. You can set this field using either the condition builder or a script.
|
|
Skip reprompting if
|
No-code condition statement or low-code script that specifies a condition for letting users skip reprompting in the conversation. When a preceding node is revisited through a topic loopback or Dialog Act, Virtual Agent bypasses this node and automatically retains its original value.
