PubNub Stream Controller: Channel Groups
Remarks
When using Channel Groups, you should not add or remove channels in your client side applications. This example shows adding channels to a channel group and subscribing to that channel group for simplicity sake. But in a real world scenario, you should have your server do all the add/remove of channels to/from channel groups. When you enable Access Manager, you will need the manage permission to add/remove channels to/from channel groups and you should never grant the manage permission to clients for security reasons. Only your server should be granted the manage permission.
