Well, I have tried everything but no joy. The tutorial video does not cover the YouTube API section of the stack but I am sure I have it correct (notwithstanding the hoops required by Google!) I simply do not see the video channel that I have set up.
I believe it is required, I have set up a Project on the Google Cloud Platform, have obtained an API, an OAuth ID and a Project ID as well as adding my Channel ID. Still not working though!
Ah. The video helped, thanks one and all, it works now. So can I use the same credentials on multiple video walls on the same site but with different Channel ID’s?
