YouTube API to fetch all videos on a channel - youtube

We need a video list by channel name of YouTube (using the API).
We can get a channel list (only channel name) by using the below API:
https://gdata.youtube.com/feeds/api/channels?v=2&q=tendulkar
Below is a direct link of channels
https://www.youtube.com/channel/UCqAEtEr0A0Eo2IVcuWBfB9g
Or
WWW.YouTube.com/channel/HC-8jgBP-4rlI
Now, we need videos of channel >> UCqAEtEr0A0Eo2IVcuWBfB9g or HC-8jgBP-4rlI.
We tried
https://gdata.youtube.com/feeds/api/videos?v=2&uploader=partner&User=UC7Xayrf2k0NZiz3S04WuDNQ
https://gdata.youtube.com/feeds/api/videos?v=2&uploader=partner&q=UC7Xayrf2k0NZiz3S04WuDNQ
But, it does not help.
We need all the videos posted on the channel. Videos uploaded to a channel can be from multiple users thus I don't think providing a user parameter would help...

You need to look at the YouTube Data API. You will find there documentation about how the API can be accessed. You can also find client libraries.
You could also make the requests yourself. Here is an example URL that retrieves the latest videos from a channel:
https://www.googleapis.com/youtube/v3/search?key={your_key_here}&channelId={channel_id_here}&part=snippet,id&order=date&maxResults=20
After that you will receive a JSON with video ids and details, and you can construct your video URL like this:
http://www.youtube.com/watch?v={video_id_here}

First, you need to get the ID of the playlist that represents the uploads from the user/channel:
https://developers.google.com/youtube/v3/docs/channels/list#try-it
You can specify the username with the forUsername={username} param, or specify mine=true to get your own (you need to authenticate first). Include part=contentDetails to see the playlists.
GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=jambrose42&key={YOUR_API_KEY}
In the result "relatedPlaylists" will include "likes" and "uploads" playlists. Grab that "upload" playlist ID.
Also note the upload playlist id is your channelId prefixed with UU instead of UC.
Next, get a list of videos in that playlist:
https://developers.google.com/youtube/v3/docs/playlistItems/list#try-it
Just drop in the playlistId!
GET https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails&maxResults=50&playlistId=UUpRmvjdu3ixew5ahydZ67uA&key={YOUR_API_KEY}

Here is a video from Google Developers showing how to list all videos in a channel in v3 of the YouTube API.
There are two steps:
Query Channels to get the "uploads" Id. eg https://www.googleapis.com/youtube/v3/channels?id={channel Id}&key={API key}&part=contentDetails
Use this "uploads" Id to query PlaylistItems to get the list of videos. eg https://www.googleapis.com/youtube/v3/playlistItems?playlistId={"uploads" Id}&key={API key}&part=snippet&maxResults=50

To get channels list :
Get Channels list by forUserName:
https://www.googleapis.com/youtube/v3/channels?part=snippet,contentDetails,statistics&forUsername=Apple&key=
Get channels list by channel id:
https://www.googleapis.com/youtube/v3/channels/?part=snippet,contentDetails,statistics&id=UCE_M8A5yxnLfW0KghEeajjw&key=
Get Channel sections:
https://www.googleapis.com/youtube/v3/channelSections?part=snippet,contentDetails&channelId=UCE_M8A5yxnLfW0KghEeajjw&key=
To get Playlists :
Get Playlists by Channel ID:
https://www.googleapis.com/youtube/v3/playlists?part=snippet,contentDetails&channelId=UCq-Fj5jknLsUf-MWSy4_brA&maxResults=50&key=
Get Playlists by Channel ID with pageToken:
https://www.googleapis.com/youtube/v3/playlists?part=snippet,contentDetails&channelId=UCq-Fj5jknLsUf-MWSy4_brA&maxResults=50&key=&pageToken=CDIQAA
To get PlaylistItems :
Get PlaylistItems list by PlayListId:
https://www.googleapis.com/youtube/v3/playlistItems?part=snippet,contentDetails&maxResults=25&playlistId=PLHFlHpPjgk70Yv3kxQvkDEO5n5tMQia5I&key=
To get videos :
Get videos list by video id:
https://www.googleapis.com/youtube/v3/videos?part=snippet,contentDetails,statistics&id=YxLCwfA1cLw&key=
Get videos list by multiple videos id:
https://www.googleapis.com/youtube/v3/videos?part=snippet,contentDetails,statistics&id=YxLCwfA1cLw,Qgy6LaO3SB0,7yPJXGO2Dcw&key=
Get comments list
Get Comment list by video ID:
https://www.googleapis.com/youtube/v3/commentThreads?part=snippet,replies&videoId=el****kQak&key=A**********k
Get Comment list by channel ID:
https://www.googleapis.com/youtube/v3/commentThreads?part=snippet,replies&channelId=U*****Q&key=AI********k
Get Comment list by allThreadsRelatedToChannelId:
https://www.googleapis.com/youtube/v3/commentThreads?part=snippet,replies&allThreadsRelatedToChannelId=UC*****ntcQ&key=AI*****k
Here all api's are Get approach.
Based on channel id we con't get all videos directly, that's the important point here.
For integration https://developers.google.com/youtube/v3/quickstart/ios?ver=swift

Here is the code that will return all video ids under your channel
<?php
$baseUrl = 'https://www.googleapis.com/youtube/v3/';
// https://developers.google.com/youtube/v3/getting-started
$apiKey = 'API_KEY';
// If you don't know the channel ID see below
$channelId = 'CHANNEL_ID';
$params = [
'id'=> $channelId,
'part'=> 'contentDetails',
'key'=> $apiKey
];
$url = $baseUrl . 'channels?' . http_build_query($params);
$json = json_decode(file_get_contents($url), true);
$playlist = $json['items'][0]['contentDetails']['relatedPlaylists']['uploads'];
$params = [
'part'=> 'snippet',
'playlistId' => $playlist,
'maxResults'=> '50',
'key'=> $apiKey
];
$url = $baseUrl . 'playlistItems?' . http_build_query($params);
$json = json_decode(file_get_contents($url), true);
$videos = [];
foreach($json['items'] as $video)
$videos[] = $video['snippet']['resourceId']['videoId'];
while(isset($json['nextPageToken'])){
$nextUrl = $url . '&pageToken=' . $json['nextPageToken'];
$json = json_decode(file_get_contents($nextUrl), true);
foreach($json['items'] as $video)
$videos[] = $video['snippet']['resourceId']['videoId'];
}
print_r($videos);
Note: You can get channel id at
https://www.youtube.com/account_advanced after logged in.

Below is a Python alternative that does not require any special packages. By providing the channel id it returns a list of video links for that channel. Please note that you need an API Key for it to work.
import urllib
import json
def get_all_video_in_channel(channel_id):
api_key = YOUR API KEY
base_video_url = 'https://www.youtube.com/watch?v='
base_search_url = 'https://www.googleapis.com/youtube/v3/search?'
first_url = base_search_url+'key={}&channelId={}&part=snippet,id&order=date&maxResults=25'.format(api_key, channel_id)
video_links = []
url = first_url
while True:
inp = urllib.urlopen(url)
resp = json.load(inp)
for i in resp['items']:
if i['id']['kind'] == "youtube#video":
video_links.append(base_video_url + i['id']['videoId'])
try:
next_page_token = resp['nextPageToken']
url = first_url + '&pageToken={}'.format(next_page_token)
except:
break
return video_links

Thanks to the references shared here and elsewhere, I've made an online script / tool that one can use to obtain all videos of a channel.
It combines API calls to youtube.channels.list, playlistItems, videos. It uses recursive functions to make the asynchronous callbacks run the next iteration upon getting a valid response.
This also serves to limit the actual number of requests made at a time, hence keeping you safe from violating YouTube API rules. Sharing shortened snippets and then a link to the full code. I got around the 50 max results per call limitation by using the nextPageToken value that comes in the response to fetch the next 50 results and so on.
function getVideos(nextPageToken, vidsDone, params) {
$.getJSON("https://www.googleapis.com/youtube/v3/playlistItems", {
key: params.accessKey,
part: "snippet",
maxResults: 50,
playlistId: params.playlistId,
fields: "items(snippet(publishedAt, resourceId/videoId, title)), nextPageToken",
pageToken: ( nextPageToken || '')
},
function(data) {
// commands to process JSON variable, extract the 50 videos info
if ( vidsDone < params.vidslimit) {
// Recursive: the function is calling itself if
// all videos haven't been loaded yet
getVideos( data.nextPageToken, vidsDone, params);
}
else {
// Closing actions to do once we have listed the videos needed.
}
});
}
This got a basic listing of the videos, including id, title, date of publishing and similar. But to get more detail of each video like view counts and likes, one has to make API calls to videos.
// Looping through an array of video id's
function fetchViddetails(i) {
$.getJSON("https://www.googleapis.com/youtube/v3/videos", {
key: document.getElementById("accesskey").value,
part: "snippet,statistics",
id: vidsList[i]
}, function(data) {
// Commands to process JSON variable, extract the video
// information and push it to a global array
if (i < vidsList.length - 1) {
fetchViddetails(i+1) // Recursive: calls itself if the
// list isn't over.
}
});
See the full code here, and live version here. (Edit: fixed github link)
Edit: Dependencies: JQuery, Papa.parse

Short answer:
Here's a library called scrapetube That can help with that.
pip install scrapetube
import scrapetube
import simplejson as json
videos = scrapetube.get_channel("UC9-y-6csu5WGm29I7JiwpnA")
for video in videos:
print(video['videoId'])
print(video['title']['runs'][0]['text'])
print(video['publishedTimeText']['simpleText'])
print('\r\n')
# DEBUG: print(json.dumps(video))
Long answer:
The module mentioned above was created by me due to a lack of any other solutions. Here's what i tried:
Selenium. It worked but had three big drawbacks: 1. It requires a web browser and driver to be installed. 2. has big CPU and memory requirements. 3. can't handle big channels.
Using youtube-dl. Like this:
import youtube_dl
youtube_dl_options = {
'skip_download': True,
'ignoreerrors': True
}
with youtube_dl.YoutubeDL(youtube_dl_options) as ydl:
videos = ydl.extract_info(f'https://www.youtube.com/channel/{channel_id}/videos')
This also works for small channels, but for bigger ones i would get blocked by youtube for making so many requests in such a short time (because youtube-dl downloads more info for every video in the channel).
So i made the library scrapetube which uses the web API to get all the videos.

Try with like the following. It may help you.
https://gdata.youtube.com/feeds/api/videos?author=cnn&v=2&orderby=updated&alt=jsonc&q=news
Here author as you can specify your channel name and "q" as you can give your search key word.

Since everyone answering this question has problems due to the 500 video limit here's an alternate solution using youtube_dl in Python 3. Also, no API key is needed.
Install youtube_dl: sudo pip3 install youtube-dl
Find out your target channel's channel id. The ID is going to start with UC. Replace the C for Channel with U for Upload (i.e. UU...), this is the upload playlist.
Use the playlist downloader feature from youtube-dl. Ideally you do NOT want to download every video in the playlist which is the default, but only the metadata.
Example (warning -- takes tens of minutes):
import youtube_dl, pickle
# UCVTyTA7-g9nopHeHbeuvpRA is the channel id (1517+ videos)
PLAYLIST_ID = 'UUVTyTA7-g9nopHeHbeuvpRA' # Late Night with Seth Meyers
with youtube_dl.YoutubeDL({'ignoreerrors': True}) as ydl:
playd = ydl.extract_info(PLAYLIST_ID, download=False)
with open('playlist.pickle', 'wb') as f:
pickle.dump(playd, f, pickle.HIGHEST_PROTOCOL)
vids = [vid for vid in playd['entries'] if 'A Closer Look' in vid['title']]
print(sum('Trump' in vid['title'] for vid in vids), '/', len(vids))

Just in three steps:
Subscriptions: list ->
https://www.googleapis.com/youtube/v3/subscriptions?part=snippet&maxResults=50&mine=true&access_token={oauth_token}
Channels: list ->
https://www.googleapis.com/youtube/v3/channels?part=contentDetails&id={channel_id}&key={YOUR_API_KEY}
PlaylistItems: list ->
https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId={playlist_id}&key={YOUR_API_KEY}

Recently I had to retrieve all videos from a channel, and according to YouTube developer documentation:
https://developers.google.com/youtube/v3/docs/playlistItems/list
function playlistItemsListByPlaylistId($service, $part, $params) {
$params = array_filter($params);
$response = $service->playlistItems->listPlaylistItems(
$part,
$params
);
print_r($response);
}
playlistItemsListByPlaylistId($service,
'snippet,contentDetails',
array('maxResults' => 25, 'playlistId' => 'id of "uploads" playlist'));
Where $service is your Google_Service_YouTube object.
So you have to fetch information from the channel to retrieve the "uploads" playlist that actually has all the videos uploaded by the channel: https://developers.google.com/youtube/v3/docs/channels/list
If new with this API, I highly recommend to turn the code sample from the default snippet to the full sample.
So the basic code to retrieve all videos from a channel can be:
class YouTube
{
const DEV_KEY = 'YOUR_DEVELOPPER_KEY';
private $client;
private $youtube;
private $lastChannel;
public function __construct()
{
$this->client = new Google_Client();
$this->client->setDeveloperKey(self::DEV_KEY);
$this->youtube = new Google_Service_YouTube($this->client);
$this->lastChannel = false;
}
public function getChannelInfoFromName($channel_name)
{
if ($this->lastChannel && $this->lastChannel['modelData']['items'][0]['snippet']['title'] == $channel_name)
{
return $this->lastChannel;
}
$this->lastChannel = $this->youtube->channels->listChannels('snippet, contentDetails, statistics', array(
'forUsername' => $channel_name,
));
return ($this->lastChannel);
}
public function getVideosFromChannelName($channel_name, $max_result = 5)
{
$this->getChannelInfoFromName($channel_name);
$params = [
'playlistId' => $this->lastChannel['modelData']['items'][0]['contentDetails']['relatedPlaylists']['uploads'],
'maxResults'=> $max_result,
];
return ($this->youtube->playlistItems->listPlaylistItems('snippet,contentDetails', $params));
}
}
$yt = new YouTube();
echo '<pre>' . print_r($yt->getVideosFromChannelName('CHANNEL_NAME'), true) . '</pre>';

Using API version 2, which is deprecated, the URL for uploads (of channel UCqAEtEr0A0Eo2IVcuWBfB9g) is:
https://gdata.youtube.com/feeds/users/UCqAEtEr0A0Eo2IVcuWBfB9g/uploads
There is an API version 3.

From https://stackoverflow.com/a/65440501/2585501:
This method is especially useful if a) the channel has more than 50 videos or if b) desire youtube video ids formatted in a flat txt list:
Obtain a Youtube API v3 key (see https://stackoverflow.com/a/65440324/2585501)
Obtain the Youtube Channel ID of the channel (see https://stackoverflow.com/a/16326307/2585501)
Obtain the Uploads Playlist ID of the channel: https://www.googleapis.com/youtube/v3/channels?id={channel Id}&key={API key}&part=contentDetails (based on https://www.youtube.com/watch?v=RjUlmco7v2M)
Install youtube-dl (e.g. pip3 install --upgrade youtube-dl or sudo apt-get install youtube-dl)
Download the Uploads Playlist using youtube-dl: youtube-dl -j --flat-playlist "https://<yourYoutubePlaylist>" | jq -r '.id' | sed 's_^_https://youtu.be/_' > videoList.txt (see https://superuser.com/questions/1341684/youtube-dl-how-download-only-the-playlist-not-the-files-therein)

Posting long after the original question was asked, but I made a python package that does this using a very simple API. It gets all the videos uploaded to a channel, but I'm not sure about this part (included in the original question):
Videos uploaded to a channel can be from multiple users thus I don't think providing a user parameter would help...
Maybe YouTube changed in the 8 years since this question was posted, but if it didn't, the package I made might not cover this case.
To use the API:
pip3 install -U yt-videos-list # macOS
pip install -U yt-videos-list # Windows
# if that doesn't work, try
python3 -m pip install -U yt-videos-list # macOS
python -m pip install -U yt-videos-list # Windows
Then open up a python interpreter
python3 # macOS
python # Windows
and run the program:
from yt_videos_list import ListCreator
lc = ListCreator()
help(lc) # display API information - shows available parameters and functions
my_url = 'https://www.youtube.com/user/1veritasium'
lc.create_list_for(url=my_url)

Like many other answers, upload id is to be retrieved from the channel id first.
import urllib.request
import json
key = "YOUR_YOUTUBE_API_v3_BROWSER_KEY"
#List of channels : mention if you are pasting channel id or username - "id" or "forUsername"
ytids = [["bbcnews","forUsername"],["UCjq4pjKj9X4W9i7UnYShpVg","id"]]
newstitles = []
for ytid,ytparam in ytids:
urld = "https://www.googleapis.com/youtube/v3/channels?part=contentDetails&"+ytparam+"="+ytid+"&key="+key
with urllib.request.urlopen(urld) as url:
datad = json.loads(url.read())
uploadsdet = datad['items']
#get upload id from channel id
uploadid = uploadsdet[0]['contentDetails']['relatedPlaylists']['uploads']
#retrieve list
urld = "https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails&maxResults=50&playlistId="+uploadid+"&key="+key
with urllib.request.urlopen(urld) as url:
datad = json.loads(url.read())
for data in datad['items']:
ntitle = data['snippet']['title']
nlink = data['contentDetails']['videoId']
newstitles.append([nlink,ntitle])
for link,title in newstitles:
print(link, title)

That's my Python solution, using Google API.
Observations:
Create a .env file to store your API Developer Key, and put it in your .gitignore file
The parameter "forUserName" should be set with the name of the Youtube Channel (username). Alternatively, you can use the channel id, setting the parameter "id", instead of "forUserName".
The object "playlistItem" gives you access to each video. I'm showing only its title but there are many other properties.

You have to get the channel_id of the video you want to get the data from.
For getting the channel_id using the video_id, you can use the videos:list endpoint of the YouTube Data API - add video_id in Id parameter. example.
Then, with the channel_id, change the second character to "U" :
This modified id is the Uploads playlist of that said YouTube channel.
With this Uploads playlist_id, you can use the Playlistitem:list endpoint of the YouTube Data API to retrieve all the uploaded videos from the channel.
In the part parameter add "id,snippet,contentDetails,status".
and in playlistID add the modified channel ID.
and then execute.

How to avoid omissions in video information acquisition when using the YouTube Data API?

Assumption / What I want to achieve
I want to use YouTube Data API V3 to get the video ID without any omissions, and find out if the cause of the trouble is in the code or in the video settings of YouTube (API side).
Problem
The following code is used to get the video information from YouTube Data API, but the number of IDs I got did not match the number of videos that are actually posted.
from apiclient.discovery
import build
id = "UCD-miitqNY3nyukJ4Fnf4_A" #sampleID
token_check = None
nextPageToken = None
id_info = []
while True:
if token_check != None:
nextPageToken = token_check
Search_Video = youtube.search().list(
part = "id",
channelId = id,
maxResults = 50,
order = 'date',
safeSearch = "none",
pageToken = nextPageToken
).execute()
for ID_check in Search_Video.get("items", []):
if ID_check["id"]["kind"] == "youtube#video":
id_info.append(ID_check["id"]["videoId"])
try:
token_check = Search_Video["nextPageToken"]
except:
print(len(id_info)) #check number of IDs
break
I also used the YouTube Data API function to get the videoCount information of the channel, and noticed that the value of videoCount did not match the number of IDs obtained by the code above, which is why I posted this.
According to channels() API, this channel have 440 videos, but the above code gets only 412 videos (at 10:30 a.m. JST).
Supplemental Information
・Python 3.9.0
・YouTube Data API v3
You have to acknowledge that the Search.list API endpoint does not have a crisp behavior. That means you should not expect precise results from it. Google does not document this behavior as such, but this forum has many posts from users experiencing that.
If you want to obtain all the IDs of videos uploaded by a given channel then you should employ the following two-step procedure:
Step 1: Obtain the ID of the Uploads Playlist of a Channel.
Invoke the Channels.list API endpoint, queried with its request parameter id set to the ID of the channel of your interest (or, otherwise, with its request parameter mine set to true) for to obtain that channel's uploads playlist ID, contentDetails.relatedPlaylists.uploads.
def get_channel_uploads_playlist_id(youtube, channel_id):
response = youtube.channels().list(
fields = 'items/contentDetails/relatedPlaylists/uploads',
part = 'contentDetails',
id = channel_id,
maxResults = 1
).execute()
items = response.get('items')
if items:
return items[0] \
['contentDetails'] \
['relatedPlaylists'] \
.get('uploads')
else:
return None
Do note that the function get_channel_uploads_playlist_id should only be called once for to obtain the uploads playlist
ID of a given channel; subsequently use that ID as many times as needed.
Step 2: Retrieve All IDs of Videos of a Playlist.
Invoke the PlaylistItems.list API endpoint, queried with its request parameter playlistId set to the ID obtained from get_channel_uploads_playlist_id:
def get_playlist_video_ids(youtube, playlist_id):
request = youtube.playlistItems().list(
fields = 'nextPageToken,items/snippet/resourceId',
playlistId = playlist_id,
part = 'snippet',
maxResults = 50
)
videos = []
is_video = lambda item: \
item['snippet']['resourceId']['kind'] == 'youtube#video'
video_id = lambda item: \
item['snippet']['resourceId']['videoId']
while request:
response = request.execute()
items = response.get('items', [])
assert len(items) <= 50
videos.extend(map(video_id, filter(is_video, items)))
request = youtube.playlistItems().list_next(
request, response)
return videos
Do note that, when using the Google's APIs Client Library for Python (as you do), API result set pagination is trivially simple: just use the list_next method of the Python API object corresponding to the respective paginated API endpoint (as was shown above):
request = API_OBJECT.list(...)
while request:
response = request.execute()
...
request = API_OBJECT.list_next(
request, response)
Also note that above I used twice the fields request parameter. This is good practice: ask from the API only the info that is of actual use.
Yet an important note: the PlaylistItems.list endpoint would not return items that correspond to private videos of a channel when invoked with an API key. This happens when your youtube object was constructed by calling the function apiclient.discovery.build upon passing to it the parameter developerKey.
PlaylistItems.list returns items corresponding to private videos only to the channel owner. This happens when the youtube object is constructed by calling the function apiclient.discovery.build upon passing to it the parameter credentials and if credentials refer to the channel that owns the respective playlist.
An additional important note: according to Google staff, there's an upper 20000 limit set by design for the number of items returned via PlaylistItems.list endpoint when queried for a given channel's uploads playlist. This is unfortunate, but a fact.

YouTube API: Get upload playlistID for YouTube Channel

I'm trying to figure out the best way to get a channel's upload playlistID given the channel's channelID. E.g. for the channel with channelID
UC9CuvdOVfMPvKCiwdGKL3cQ
The corresponding upload playlistID is
UU9CuvdOVfMPvKCiwdGKL3cQ
Notice the second character has changed from a "C" to a "U"
I can do this transformation via string manipulation, but I'm curious if there's a better, less hacky way to find the upload playlist ID through the official youtube api.
Here's some Kotlin code that shows my issue:
I can find the ChannelID for the "Game Grumps" channel through the following youtube api v3 search:
val req = youtube.search().list("snippet");
req.key = {API_KEY}
req.q = "Game Grumps"
req.type = "channel"
val response = req.execute();
The resulting Channel id (response.items[0].snippet.channelId) is UC9CuvdOVfMPvKCiwdGKL3cQ
But when I run the following to try to get the videos uploaded by the channel, I have to use the transformed ChannelID (starting with UU instead of UC)
val req = youtube.PlaylistItems().list("snippet")
req.playlistId = "UU9CuvdOVfMPvKCiwdGKL3cQ"
req.key = {API_KEY}
val response = req .execute()
If I use the untransformed "UC" channelID, I get the following error: The playlist identified with the requests playlistId parameter cannot be found.
Instead of just replacing the second character with a "U", what's the more robust way (e.g. using the youtube API) of translating a ChannelID to a PlaylistID (for the uploads from that channel)?
I would suggest using the official Youtube API, instead of trying to manipulate the strings. You can follow the instructions here:
Instructions to get video ids for all uploaded videos for a channel in V3
Get the channel id for the channel you want (you probably only need to do this once, then you can save it)
Use search.list
Set type to channel
Set q to the name of the channel you want
Grab the channel id (something like this: "channelId": "UC0X2VuXXXXXXXXXXXXXXXX")
Get the playlist id for the channel uploads using the channel id from step 1 (you probably only need to do this once, then you can save it)
Use channels.list
Set id to UC0X2VuXXXXXXXXXXXXXXXX from step 1
Grab the uploads key from contentDetails (something like this: "uploads": "UU0XXXXXXXXXXXXXXXXXXXX")
Get the videos via the playlistitems in the playlist using the playlist id from step 2
Use playlistItems.list
Set playlistId to UU0XXXXXXXXXXXXXXXXXXXX from step 2
Go through each PlaylistItem and pull out the video id

YouTube API V3 - Get recommended video for new feed

As YouTube official documentation about implement and immigrate to API V3, they said:
YouTube Data API (v2) functionality: Retrieve video recommendations
The v3 API does not retrieve a list that only contains videos recommended for the current API user. However, you can use the v3 API to find recommended videos by calling the activities.list method and setting the home parameter value to true.
But now the parameter home has been deprecated too.
Currently, when I set the home parameter to true, I only retrieve the recently uploaded video in the channel: Popular video in YouTube. There are no video with snippet.type=recommendation at all.
I need to show recommended videos of authenticated user in new feed, but seem like this feature is completely deprecated by YouTube.
Anyone has solution for that?
Thanks first!
Unfortunately, I can't find any documentation or example about this feature. It seems that this has been deprecated. However, you may check this documentation with sample JSON structure that shows the format of a activities resource such as recommendation:
"recommendation": {
"resourceId": {
"kind": string,
"videoId": string,
"channelId": string,
},
Hope this helps!
I found this youtubes search api. All we need to do is put a video id in the relatedToVideoId and it'll giveout a list of videos related to it.
The docs for the api include a way to test the request. code samples there show how to set 'mine' for an authenticated request.
youtube activities
This is android sample code. it would need to be in some background thread. The setmine = true on the channelList response is like the home (I think). Was not sure if your implementation was for the web or an app.
this is android code:
YouTube youtube = new YouTube.Builder(transport, jsonFactory,
credential).setApplicationName(getString(R.string.app_name))
.build();
YouTube.Activities.List activities;
ActivityListResponse activityListResponse = null;
List<ActivityData> activitiesData = new ArrayList<ActivityData>();
try {
/*
* Now that the user is authenticated, the app makes a
* channels list request to get the authenticated user's
* channel. Returned with that data is the playlist id for
* the uploaded videos.
* https://developers.google.com/youtube
* /v3/docs/channels/list
*/
ChannelListResponse clr = youtube.channels().list("contentDetails")
.setMine(true).execute();
activities = youtube.activities().list("id,snippet,subscriberSnippet");
activities.setChannelId(clr.getItems().get(0).getId());
activities.setMaxResults((long) 50);
activityListResponse = activities.execute();
ArrayList<String> subscriptionListIdentifier = new ArrayList<String>()
,listTitles = new ArrayList<String>()
,listThumbnails = new ArrayList<String>();
List<Activity> results = activityListResponse.getItems();
for (Activity activity : results) {
listTitles.add(activity.getSnippet().getTitle());
listThumbnails.add(activity.getSnippet().getThumbnails().getDefault().getUrl());
subscriptionListIdentifier.add(activity.getId());
//if ("public".equals(playlist.getStatus()
// .getPrivacyStatus())) {
ActivityData data = new ActivityData();
data.setActivity(activity);
activitiesData.add(data);
//}
}
return activitiesData;
You can retrieve them using the following API call:
GET https://www.googleapis.com/youtube/v3/activitiespart=snippet%2CcontentDetails&channelId={channel—_Id}&maxResults=25&regionCode=tw&key={YOUR_API_KEY}

YouTube API PlaylistItems/list limited to 5000 results?

I am trying to get a list of all titles from YouTube channel machinima. Machinima currently has (I'm guessing here) tens of thousands of videos.
The following Python script is supposed to walk the chain of pages containing playlist items (the playlist being user's uploads).
channels_response = youtube.channels().list(
id=DEFAULT_CHANNEL,
part="contentDetails"
).execute()
if len(channels_response["items"]) == 0:
channels_response = youtube.channels().list(
forUsername=DEFAULT_CHANNEL,
part="contentDetails"
).execute()
for channel in channels_response["items"]:
# From the API response, extract the playlist ID that identifies the list
# of videos uploaded to the authenticated user's channel.
uploads_list_id = channel["contentDetails"]["relatedPlaylists"]["uploads"]
print "Videos in list %s" % uploads_list_id
# Retrieve the list of videos uploaded to the authenticated user's channel.
playlistitems_list_request = youtube.playlistItems().list(
playlistId=uploads_list_id,
part="snippet",
maxResults=50
)
while playlistitems_list_request:
playlistitems_list_response = playlistitems_list_request.execute()
# Print information about each video.
for playlist_item in playlistitems_list_response["items"]:
title = playlist_item["snippet"]["title"]
video_id = playlist_item["snippet"]["resourceId"]["videoId"]
print video_id
videos.append(video_id)
titles.append(title)
playlistitems_list_request = youtube.playlistItems().list_next(
playlistitems_list_request, playlistitems_list_response)
However, for some reason, I always end up getting no more than 5,000 videos.
I checked the API documentation, but there is no reference of limit of such sort. The code I'm using is from the official documentation too (slightly modified) and should work.
Does anyone know how could I get ALL the videos from Machinima?
EDIT: Update on October 20th. The limit seems to have disappeared.

Retrieving individual videos view count - Youtube API V3.0 - JavaScript

I've been trying to get the view count on videos that I query through the following method:
function search() {
var request = gapi.client.youtube.search.list({
part: 'snippet',
channelId: 'IRRELEVANT',
order: 'date',
maxResults: '25'
});
request.execute(function(response){
YoutubeResponse(response);
});
While the documentation tells me that there's a statistics portion to every video, after the snippet I have __proto__ which I guess means there was an error somewhere? or did the API change? Essentially I need the view count of those 25 most recent videos...
I tried changing part: 'snippet' to part: 'statistics' but got back a code: -32602...
Thanks for the help,
Cheers!
EDIT: Apparently the search.list doesn't have the "statistics" but rather I need to search every video individually... The thing is, when using googles "Try It" feature (https://developers.google.com/youtube/v3/docs/videos/list#try-it) when you ask for the statistics in the "Fields" part at the bottom, it doesn't do anything... So I am VERY confused as to how the heck can I get the view counts & length of all 25 videos (if individually or all at once - preferably-)
The link you gave https://developers.google.com/youtube/v3/docs/videos/list#try-it is working for me.
To get duration and viewCount: Fill in for part: contentDetails,statistics and for id: a comma-separated-list of video-id's like: TruIq5IxuiU,-VoFbH8jTzE,RPNDXrAvAMg,gmQmYc9-zcg
This will create a request as:
GET https://www.googleapis.com/youtube/v3/videos?part=contentDetails,statistics&id=TruIq5IxuiU,-VoFbH8jTzE,RPNDXrAvAMg,gmQmYc9-zcg&key={YOUR_API_KEY}
Agree with the answer provided by #Als.
But I found a code snippet which might be more convenient for some of you:
function youtube_view_count_shortcode($params)
{
$videoID = $params['id']; // view id here
$json = file_get_contents("https://www.googleapis.com/youtube/v3/videos?
part=statistics&id=" . $videoID . "&key=xxxxxxxxxxxxxxxxxxxxxxxx");
$jsonData = json_decode($json);
$views = $jsonData->items[0]->statistics->viewCount;
return number_format($views);
}
Replace the key value with the google api key for youtube data API and the video id with the youtube video id and Voila you get the total number of views for the youtube video.
