I am researching developing a channel for a client that already has an established streaming service on the web. They want to offer free and premium streams on Roku.
The premium stream would be for established subscribers and would require the user to enter their subscription credentials, email and password. This would then authenticate with the streaming service.
Is it required that the channel also offer paid subscriptions through Roku Pay?
I have gone over the authentication flow chart and it is not real clear to me how this use case would be resolved.
