Yes, I know.
user.username variable is same with channel_id.
My channel url is ‘https://www.twitch.tv/poXXXXX’.
And, My display name is poXXXXX.
And user.username variable is displayname.
And, I checked it through this below.
fetch(‘https://api.twitch.tv/kraken/channels/<%=user.username%>’,
Is my opinion correct?
