You can use wordpress automatic plugin to post videos from youtube to your wordpress account for any channel
the channel id appear at the channel link after the “channel/” part
as example here is a youtube channel link
https://www.youtube.com/channel/UCv2oaoQ9-yq2ZWkGPDQaUZw
the id for this channel is “UCv2oaoQ9-yq2ZWkGPDQaUZw” without quotes
What if the channel link does not contain the “channel/” part?
let’s say you have the channel link with the user other than the channel id like the following link
https://www.youtube.com/user/NatGeoWILD2014
with this link there is no channel id appear at it so do the following to get the channel link from this link
- Visit the channel link like this https://www.youtube.com/user/NatGeoWILD2014
- open any video posted by this channel
- copy the channel link from the video page
- now you can get the channel id that appears after the “/channel”
