Manage channel updates

Update channel metadata and receive real-time change events.

Requires App Context

Enable App Context for your keyset in the Admin Portal.

Update channel details

Edit channel metadata with Update() or UpdateChannel().

Both methods produce the same result. Call Update() on a Channel object or UpdateChannel() on the Chat object with the channel ID.

Method signature

These methods take the following parameters:

• Update()

  1channel.Update(ChatChannelData updatedData)
  2
  
  3public class ChatChannelData
  4{
  5    public string Name { get; set; } = string.Empty;
  6    public string Description { get; set; } = string.Empty;
  7    public Dictionary<string, object> CustomData { get; set; } = new ();
  8    public string Status { get; set; } = string.Empty;
  9    public string Type { get; set; } = string.Empty;
  10}

• UpdateChannel()

  1chat.UpdateChannel(
  2    string channelId, 
  3    ChatChannelData updatedData
  4)
  5
  
  6public class ChatChannelData
  7{

Get channel updates

Receive updates when Channel objects are edited or deleted:

• StreamUpdates() - monitors a single channel
• StreamUpdatesOn() - monitors multiple channels

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

Call StreamUpdates(true) to enable the OnUpdated and OnDeleted events on the channel entity. OnUpdated fires when channel metadata changes. OnDeleted fires when the channel 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 This method has been superseded by StreamUpdates(), though it remains available for backward compatibility.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()

  1channel.StreamUpdates(bool stream)

• OnUpdated

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

• OnDeleted

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

• StreamUpdatesOn() (static)

  1Channel.StreamUpdatesOn(
  2    List<Channel> channels,
  3    Action<Channel> listener
  4)

Input

Parameter	Required in StreamUpdates()	Required in OnUpdated / OnDeleted	Required in StreamUpdatesOn()	Description
stream Type: bool Default: n/a	Yes	n/a	n/a	Whether to start (true) or stop (false) listening to Channel object updates.
channels Type: List<Channel> Default: n/a	No	No	Yes	List of Channel objects for which you want to get updates.
listener Type: Action<Channel> Default: n/a	No	No	Yes	Callback that receives the specific channel that was updated.

Output

These methods don't return a value. Updates are delivered through event handlers or callback functions.
