The following input controls are available for capturing user responses:
* **Text:** Users can enter up to 5000 characters.
* **Static Choice:** Users select from a predefined list with a maximum of 20 characters per label. A user can see up to 13 quick replies at a time.
* **Boolean:** Users provide a Yes or No response.
* **File Picker:** Users can send files of types JPG, PNG, BMP, and MP4 with specific size limits (10 MB for images, 200 MB for videos).
* **Date Time:** Users select a date, time, or both.
* **Carousel:** Users choose an item from a carousel of up to 10 images, each with character limits on title and text.
## Bot Responses
Bot responses supported in the Virtual Agent Designer include:
* **Text:** Sends a plain text response.
* **Image:** Sends an image to the user.
* **Link:** Sends a web link.
* **Web UI Image Card:** Sends compact content with an image and text from a record.
* **Table:** Displays information in table format.
For further configuration details, refer to the Assistant Designer documentation on user input controls and bot responses.
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](https://www.servicenow.com/docs/ZSHubJIiz1AbowMvQgaAog "The Assistant Designer Asset library includes a diagram tool for creating and managing assets, which are blueprints for conversations between a Virtual Agent and a user. You can design topics that help your users resolve common work issues or guide them through self-service tasks.").
## User notification consent {#messg-line-capture-info__section_ijp_jfb_pqb}
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](https://www.servicenow.com/docs/access?context=c_SubscriptionBasedNotifications&version=australia&pubname=australia-platform-administration&ft:locale=en-US) for more information.
