Hi Rahul, we are currently exploring the possibility of implementing a use case where users can mute selected channels with the same custom channel type. Specifically, we want to allow users to mute notifications from all channels with the product type. Based on my research, I found that we can update the notification preference for a channel and retrieve all channels with the same custom type, then update their notification preferences in a loop. However, I was wondering if there is an alternative approach to achieve this.

Hello Yoong,
Please check below documentation and let me know if this helps:
