How can I get YouTube channel ID using channel name URL?

Question

I have made a program where users provide a YouTube channel URL and in return I will show the user its channel ID.

Like if someone puts URL like: https://youtube.com/@AndreoBee then I will return its channel ID.

const axios = require('axios');

async function getChannelId(url) {
  const channelUsername = url.split('/').pop();
  const response = await axios.get(`https://www.googleapis.com/youtube/v3/channels?part=id&forUsername=${channelUsername}&key=myapi`);

  if (response.data.items.length === 0) {
    throw new Error(`Channel not found: ${url}`);
  }

  console.log(response.data.items[0].id);
}

getChannelId('https://www.youtube.com/@AndreoBee');

Output:

/home/runner/ytcheck/index.js:7 if (response.data.items.length === 0) { ^

TypeError: Cannot read properties of undefined (reading 'length') at getChannelId (/home/runner/ytcheck/index.js:7:27)

Answer 1

You can try the following node.js script

var https = require('https');

var url = "https://www.youtube.com/@adnantoky"

https.get(url, function (res) {
    var data = '';
    res.on('data', function (chunk) {
        data += chunk;
    });
    res.on('end', function () {
        let arr = data.split('channel_id=');
        console.log("Channel ID:", arr[1].slice(0, 24));
    });
}).on('error', function (e) {
    console.log(e.message);
});
