Messenger

Setup

The setup form consists of demo channel and brand channel options, and can only be configured when they channel is being set up for the first time.
##Production vs. Demo
A production channel is intended to be used by your customers and end users. A demo channel is intended to be used for internal testing of experiences before they're deployed to your production channel. Demo channel users will not show up in analytics, so your testing will not impact your production analytics The setup for each channel is slight different.
