I am working on a project where I have an external application call a Google Apps Script Function whose purpose is to retrieve the id's of the most recent uploads on a youtube channel. The script provided by google works very well at getting the video id's:
/**
* This function retrieves the user's uploaded videos by:
* 1. Fetching the user's channel's.
* 2. Fetching the user's "uploads" playlist.
* 3. Iterating through this playlist and logs the video IDs and titles.
* 4. If there is a next page of resuts, fetching it and returns to step 3.
*/
function retrieveMyUploads() {
try {
// @see https://developers.google.com/youtube/v3/docs/channels/list
const results = YouTube.Channels.list('contentDetails', {
mine: true
});
if (!results || results.items.length === 0) {
console.log('No Channels found.');
return;
}
for (let i = 0; i < results.items.length; i ) {
const item = results.items[i];
/** Get the channel ID - it's nested in contentDetails, as described in the
* Channel resource: https://developers.google.com/youtube/v3/docs/channels.
*/
const playlistId = item.contentDetails.relatedPlaylists.uploads;
let nextPageToken = null;
do {
// @see: https://developers.google.com/youtube/v3/docs/playlistItems/list
const playlistResponse = YouTube.PlaylistItems.list('snippet', {
playlistId: playlistId,
maxResults: 25,
pageToken: nextPageToken
});
if (!playlistResponse || playlistResponse.items.length === 0) {
console.log('No Playlist found.');
break;
}
for (let j = 0; j < playlistResponse.items.length; j ) {
const playlistItem = playlistResponse.items[j];
console.log('[%s] Title: %s',
playlistItem.snippet.resourceId.videoId,
playlistItem.snippet.title);
}
nextPageToken = playlistResponse.nextPageToken;
} while (nextPageToken);
}
} catch (err) {
// TODO (developer) - Handle exception
console.log('Failed with err %s', err.message);
}
}
Unfortunately, I cannot figure out how to actually use the output of this function for my application. From what I can see, the function simply prints the id's to the execution log, but I am wondering if there is a way to put the output into an array? I have seen this SO post that accomplishing the same task. However, I am wondering if it can be done using the script that google provides in their documentation.

If I understand your question...you want an array of uploaded videos from a given channel. If so, you need to create an array where to store the results.
Here is a tested fucntion that gets the uploaded videos from a given channel:
function getUploadedVideos() {
try {
// Call uploaded videos from channel "Listen To This":
/** Array with the data. */
var array_videos = [];
/** Token pagination. */
var nextPageToken = "";
/** Channel "Listen To This". */
var channel_id = "UC6ZVjGqRf7elKAcYTXCaIsw";
/** "upload" playlist = it's the channel_id, but change the first letters "UC" to "UU" */
var uploads_playlist_id = ("UU" channel_id.substr(2, channel_id.length));
/**
* Get all uploaded videos by the channel.
*/
do {
const playlistResponse = YouTube.PlaylistItems.list('snippet', {
playlistId: uploads_playlist_id, // also works with "mine: true" for get YOUR uploaded videos.
maxResults: 50,
// Here, the first time the call is made, the "nextPageToken" value
// is empty. In every iteration (if "nextPageToken" is retrieved),
// the "nextPageToken" is used - in order to get the next page.
pageToken: nextPageToken
});
if (!playlistResponse || playlistResponse == undefined) {
Logger.log('No playlist found.');
SpreadsheetApp.getUi().alert("No playlist found.");
break;
}
// Write the videos returned in the response:
for (let j = 0; j < playlistResponse.items.length; j ) {
const mySubItem = playlistResponse.items[j];
array_videos.push(mySubItem.snippet.resourceId.videoId);
}
// Check the token:
try {
if (playlistResponse.nextPageToken != null || playlistResponse.nextPageToken != undefined) {
nextPageToken = playlistResponse.nextPageToken;
} else {
nextPageToken = undefined;
break;
}
} catch (ex_page) {
// An error occurred. Check closely the code.
Logger.log("An error occurred. Check closely the code.");
}
} while (nextPageToken != undefined);
// Print the results:
Logger.log(array_videos);
} catch (ex) {
Logger.log("Error at getting Marvel videos: %" ex);
}
}
Result:

This was able to grab the id of the most recent video uploaded on a channel and is a cleaned up version of above grabbed from here:
function retrieveMyUploads3() {
var results = YouTube.Channels.list('contentDetails', {mine: true});
for(var i in results.items) {
var item = results.items[i];
// Get the playlist ID, which is nested in contentDetails, as described in the
// Channel resource: https://developers.google.com/youtube/v3/docs/channels
var playlistId = item.contentDetails.relatedPlaylists.uploads;
var playlistResponse = YouTube.PlaylistItems.list(`snippet`, {
playlistId: playlistId,
maxResults: 1,
});
var chunk = playlistResponse.items.shift()
var theID = chunk.snippet.resourceId.videoId.toString()
return theID
}
}
Not quite an array of many different one's but I am sure it can be looped to build the array of id's and serves as a condensed way to get ahold of the video id's compared to the original google version if you don't need id's beyond the first page of results
