User object

User refers to a single user in a chat.

Properties

The User class has the following properties:

public class User : UniqueChatEntity {
    public string Id { get; protected set; }
    public string UserName { get; }
    public string ExternalId { get; }
    public string ProfileUrl { get; }
    public string Email { get; }
    public string CustomData { get; }
    public string Status { get; }
    public string DataType { get; }
    public bool Active { get; }
    public string LastActiveTimeStamp { get; }
}

Parameter	Type	Description
Id	string	Unique identifier for the user.
UserName	string	Display name or username of the user.
ExternalId	string	Identifier for the user from an external system, such as a database or CRM.
ProfileUrl	string	URL to the user's profile or avatar image.
Email	string	User's email address.
CustomData	string	Any custom data that you want to store for the user.
Status	string	Current status of the user (e.g., online, offline, away).
DataType	string	Type of user's data.
Active	bool	Returned info on whether the user is active (true) or not active (false) on the channel. The returned value depends strictly on how you configure your chat app during initialization - if you set the StoreUserActivityInterval parameter to the default 600000 milliseconds (10 minutes) and the user has been active in the app within the last 10 minutes (based on their LastActiveTimeStamp property), accessing the Active property returns true.
LastActiveTimeStamp	string	Timestamp for the last time the user was active in a chat app.
