Hi - We have a client that would like a channel that offers primarily free content but is interested in allowing some of their premium content to be made available for streaming on the same channel. The flow would have the user call a toll-free number to get some kind of PIN or access code which would allow them to view specific premium content. Without the PIN, all viewers would still have access to the rest of the content. Wondering if this is possible and/or if it's related to the in-app purchase process or is that only for 3rd party billing. Thanks for any help!
