How to get youtube channel id using channel custom name?

Question

My question is very similar to this one, I want to get channel id using channel custom name.

The answer on the question mentioned above which is:

GET https://www.googleapis.com/youtube/v3/search?part=id%2Csnippet&q=annacavalli&type=channel&key={YOUR_API_KEY}

doesn't work on small channels, for ex. when I run it with this channel: https://www.youtube.com/AnnaShearerfashionfettish it returns nothing.

Answer 1

It's very easy, using curl and grep.

Command

channel_name='DOVASYNDROMEYouTubeOfficial' #change this as you like
curl --silent "https://www.youtube.com/c/${channel_name}/videos" |\
    grep -o -P '(?<=canonical" href="https://www.youtube.com/channel/)[^"]*'

Output
