Get all playlist ids from channel id - youtube api v3 - youtube

Question

I am currently learning the use of the youtube api. I want to retrieve all playlists id from a channel id. I read through the documentation and saw that I can use youtube.channels.list for such task. I did basic testing on the api_page. Still, I am not able to figure what params to use to get the playlist id. How can I retrieve all playlist ids from a given channel id?
https://www.googleapis.com/youtube/v3/channels?part=id&id=UCF0pVplsI8R5kcAqgtoRqoA&key={YOUR_API_KEY}

Answer 1

A simple way :
With the YouTube API v3 with the ressource playlists.list
Use this parameters to get the playlists ID of a channel :
part: 'snippet'
channelId: 'UCBkNpeyvBO2TdPGVC_PsPUA'
https://www.googleapis.com/youtube/v3/playlists?part=snippet&channelId=UCBkNpeyvBO2TdPGVC_PsPUA&key={YOUR_API_KEY}
The output :
"items": [
{
"kind": "youtube#playlist",
"etag": "\"PSjn-HSKiX6orvNhGZvglLI2lvk/K21sgPQuMRCjhSMBjm3v3n5tl1o\"",

This is a sample example with a random channel.
If you don't know how to get the channelID of a channel use ressource channels.list:
With this parameters to get the video ID of a playlist :
part: 'id'
forUsername: 'channel_name'
https://www.googleapis.com/youtube/v3/channels?part=id&forUsername=GEazyTV&key={YOUR_API_KEY}
"items": [
{
"kind": "youtube#channel",
"etag": "\"PSjn-HSKiX6orvNhGZvglLI2lvk/vIwM6ev74Om0AOupX26jJoEDELU\"",
"id": "UCBkNpeyvBO2TdPGVC_PsPUA"
}

I'm not sure how I came across this solution, but I've found that if you follow these steps then you can retrieve the playlistID to use:
Create an API Key using the Google API Console.
Use
https://www.googleapis.com/youtube/v3/channels?part=contentDetails&key=[KEY FROM GOOGLE API CONSOLE]&id=[CHANNEL ID]
where you are replacing everything, including the brackets, with the corresponding info (I find channel ids are easy to come by since they are normally in the URL. The PlaylistID is the one that tends to be difficult).
The resulting feed from the URL in step 2 should contain an uploads object, containing the playlistID which is used in the URL in step 4.
Use
https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId=[PLAYLIST ID RETRIEVED IN STEP 3 HERE]&key=[KEY FROM GOOGLE API CONSOLE]
The link from step 4 is what should end up being used in the app.
This works for me every time, and I integrate the YouTube v3 API in many apps. I completely agree with #Utkanos' comment that while #mpgn's answer works sometimes, it certainly doesn't work for all channels.
