API limits

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

Output​

Both methods return an awaitable Task.

Sample code​

  • Update()

    1

  • UpdateUser()

Get user updates​

Receive updates when User objects are edited or deleted:

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

Both methods accept a callback invoked when user metadata changes. They subscribe to a channel and add an objects event listener for uuid events.

Call StreamUpdates(true) to enable the OnUpdated and OnDeleted events on the user entity. OnUpdated fires when user metadata changes. OnDeleted fires when the user is hard-deleted from App Context.

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 This method has been superseded by StreamUpdates(), though it remains available for backward compatibility.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)

  • OnUpdated

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

  • OnDeleted

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

  • StreamUpdatesOn() (static)

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