Retrieve a channel by URL

Since a channel URL is a unique identifier of a channel, you can use it when retrieving a channel object.

Open channelGroup channel

const channel = sb.openChannel.getChannel(CHANNEL_URL);

const channelName = channel.name;

We recommend that you store a user's channel URLs to handle the lifecycle or state changes of your app, or any other unexpected situations. For example, when a user is disconnected from the Sendbird server due to switching to another app temporarily, you can provide a smooth restoration of the user's state using a stored URL to fetch the appropriate channel instance.
