Hi @Ashok.S,

Welcome to the Sendbird Community. This can be achieved by first retrieving the channel object via the URL:

> **[Group channel | Chat iOS SDK | Sendbird Docs](https://sendbird.com/docs/chat/v3/ios/guides/group-channel#2-retrieve-a-channel-by-url)**
>
> Learn about the features of a group channel.

Then by joining the channel:

> **[Group channel | Chat iOS SDK | Sendbird Docs](https://sendbird.com/docs/chat/v3/ios/guides/group-channel#2-join-a-channel-as-a-member)**
