Thanks for the reply! Even more, thanks for the multiple replies and great examples I followed (like your implicit auth example; super helpful!). By the way, how do you do live examples / tests for subscriptions or bits redemption? Do you / your broadcaster pay for them to test them?
I noticed something even more devious about the examples… The bits redemption example claims “is_anonymous” field is in the message (same scope as “message_type”) but it is actually in the “data” field 
I’ll close this and post in the correct section; thanks for the tip!
