    • Use the collection of input controls provided by the Virtual Agent Designer to prompt and capture information from the user in a LINE chat conversation.

    Virtual Agent Designer is a diagram tool for creating and managing topics, which are blueprints for conversations between a virtual agent and user. For more information, see Using Virtual Agent Designer.

    User notification consent

    Users must opt in to receive notifications. No notifications can be delivered until the user grants consent.

    There are two ways for users to grant consent to receive notifications:
    • The user can enter Notification into the LINE chat with your business. The user gets a bot response with the option to subscribe or unsubscribe from receiving notifications for your business on LINE.
    • As an administrator, you can set up the option for users to subscribe or unsubscribe from notifications from your portal. See Subscription-based notifications for more information.

    User input controls

    The Conversational Integration with LINE application supports the following user input controls in Virtual Agent Designer.

    表 : 1. Supported user input controls
    User input control Description
    Text User enters a plain text string in the conversation.

    The maximum character limit is 5000 characters.
    Static Choice User selects an item from a predefined list.

    In a quick reply, the label has the maximum character limit of 20 characters. At a time, a user can view only 13 quick replies. If there are more than 13 quick replies, the pagination format is used to view more options. The default value of the maximum number of replies for a page is set in the sn_va_line.max.picker.choices system property. The property is located in the System Property [sys_properties] table.
    Boolean User enters a Boolean response to the bot. For example, the user can reply Yes or No in a chat conversation.
    File Picker User sends a file to the bot.
    The supported file types are JPG, PNG, BMP, and MP4. Files have a maximum size limit based on file type:
    • For images, the maximum size limit is 10 MB.
    • For videos, the maximum size limit is 200 MB.
    Date Time User selects a calendar date, time (hours and minutes), or both.
    Carousel User selects a single item from the carousel.

    In a carousel, the title for an image has a maximum limit of 40 characters and the text for the image has a maximum character limit of 60 characters. At a time, a user can view only 10 images. If there are more than 10 images, the pagination format is used to view more options. The default value of the maximum number of images in the carousel for a page is set in the sn_va_line.max.carousel.cards system property. The property is located in the System Property [sys_properties] table.
