Youtube API - No Channel Name

Question

I am trying to get the name of a Youtube channel using the Youtube data API, but I am getting an empty element. I have a channel in my Youtube account, so it should return it.

These are the query properties that I entered -

part:'contentDetails', forUsername: 'Seong+Lee',

to get the next answer on their interactive page.

 "etag": "\"fpJ9onbY0Rl_LqYLG6rOCJ9h9N8/C3QZ-VsykvkpW2zCm7VjGBCayqc\"",
 "pageInfo": {
  "totalResults": 0,
  "resultsPerPage": 5
 },
 "items": [
 ]
}

In my application, I get the same answer, so I decided there was no problem with my request code. Why can't I get the channel name?

Answer 1

You can get contentDetailsusing your channel id.

GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&id=UCwy6X3JB24VTsDFqMwdO5Jg&key={YOUR_API_KEY}

Your username is clearly invalid.
