API limits

To learn about the maximum length of parameters used to set user metadata, refer to REST API docs.

Output​

  • UpdateUser()

Get user updates​

Receive updates when User objects are edited or removed:

  • StreamUpdates() - monitors a single user
  • StreamUpdatesOn() - monitors multiple users

Both methods subscribe the current user to a channel and add an objects event listener for uuid events.

Change types

For details on ChatEntityChangeType values (Updated and Deleted) and their meaning, see Change types.

Stream update behavior
  • StreamUpdates() enables listening for updates on a single user. Use the OnUserUpdated or OnUpdate events to handle changes.
  • StreamUpdatesOn() has two overloads:
    • StreamUpdatesOn(List<User>, Action<List<User>>) returns the complete list of users you're monitoring each time any change occurs to any of them.
    • StreamUpdatesOn(List<User>, Action<User, ChatEntityChangeType>) returns only the specific user that was updated along with the type of change (Updated or Deleted).
Method naming

Earlier versions used SetListeningForUpdates() to enable streaming. This method has been superseded by StreamUpdates(), though it remains available for backward compatibility.

Method signature​

These methods take the following parameters:

  • StreamUpdates()

    1user.StreamUpdates(bool stream)

  • OnUserUpdated

    1// event on the User entity
    2public event Action<User> OnUserUpdated;
    3// needs a corresponding event handler
    4void EventHandler(User user)

  • OnUpdate

    1// event on the User entity
    2public event Action<User, ChatEntityChangeType> OnUpdate;
    3// needs a corresponding event handler
    4void EventHandler(User user, ChatEntityChangeType changeType)

  • StreamUpdatesOn() (static) - returns all users

    1User.StreamUpdatesOn(
    2    List<User> users,
    3    Action<List<User>> listener
    4)

  • StreamUpdatesOn() (static) - returns individual user with change type

    1User.StreamUpdatesOn(
    2    List<User> users,
    3    Action<User, ChatEntityChangeType> listener
    4)
