Ustream Requesting Our App ID

We are developing a channel with a live feed coming through Ustream. However, Ustream is requesting our "app id" in order to white list the Roku app/channel and to get access to their API key (here are their words: The app ID should be a two-part string (for example: tv.ustream.roku). The app ID will allow us to whitelist your app and provide you with a fully functional API key.). We cannot locate what they are asking for in our developer dashboard for the channel. Can anyone suggest where we might locate our app id?
