PlaylistItems: list

Returns a collection of playlist items that match the API request parameters. You can retrieve all of the playlist items in a specified playlist or retrieve one or more playlist items by their unique IDs.

Quota impact: A call to this method has a quota cost of 1 unit in addition to the costs of the specified resource parts.

Common use cases

Request

HTTP request

GET https://www.googleapis.com/youtube/v3/playlistItems

Parameters

The following table lists the parameters that this query supports. All of the parameters listed are query parameters.

Parameters
Required parameters
part string
The part parameter specifies a comma-separated list of one or more playlistItem resource properties that the API response will include.

If the parameter identifies a property that contains child properties, the child properties will be included in the response. For example, in a playlistItem resource, the snippet property contains numerous fields, including the title, description, position, and resourceId properties. As such, if you set part=snippet, the API response will contain all of those properties.

The following list contains the part names that you can include in the parameter value and the quota cost for each part:
  • contentDetails: 2
  • id: 0
  • snippet: 2
  • status: 2
Filters (specify exactly one of the following parameters)
id string
The id parameter specifies a comma-separated list of one or more unique playlist item IDs.
playlistId string
The playlistId parameter specifies the unique ID of the playlist for which you want to retrieve playlist items. Note that even though this is an optional parameter, every request to retrieve playlist items must specify a value for either the id parameter or the playlistId parameter.
Optional parameters
maxResults unsigned integer
The maxResults parameter specifies the maximum number of items that should be returned in the result set. Acceptable values are 0 to 50, inclusive. The default value is 5.
onBehalfOfContentOwner string
This parameter can only be used in a properly authorized request. Note: This parameter is intended exclusively for YouTube content partners.

The onBehalfOfContentOwner parameter indicates that the request's authorization credentials identify a YouTube CMS user who is acting on behalf of the content owner specified in the parameter value. This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and get access to all their video and channel data, without having to provide authentication credentials for each individual channel. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.
pageToken string
The pageToken parameter identifies a specific page in the result set that should be returned. In an API response, the nextPageToken and prevPageToken properties identify other pages that could be retrieved.
videoId string
The videoId parameter specifies that the request should return only the playlist items that contain the specified video.

Request body

Do not provide a request body when calling this method.

Response

If successful, this method returns a response body with the following structure:

{
  "kind": "youtube#playlistItemListResponse",
  "etag": etag,
  "nextPageToken": string,
  "prevPageToken": string,
  "pageInfo": {
    "totalResults": integer,
    "resultsPerPage": integer
  },
  "items": [
    playlistItem Resource
  ]
}

Properties

The following table defines the properties that appear in this resource:

Properties
kind string
Identifies the API resource's type. The value will be youtube#playlistItemListResponse.
etag etag
The Etag of this resource.
nextPageToken string
The token that can be used as the value of the pageToken parameter to retrieve the next page in the result set.
prevPageToken string
The token that can be used as the value of the pageToken parameter to retrieve the previous page in the result set.
pageInfo object
The pageInfo object encapsulates paging information for the result set.
pageInfo.totalResults integer
The total number of results in the result set.
pageInfo.resultsPerPage integer
The number of results included in the API response.
items[] list
A list of playlist items that match the request criteria.

Examples

Note: The following code samples may not represent all supported programming languages. See the client libraries documentation for a list of supported languages.

Go

This code sample calls the API's playlistItems.list method to retrieve a list of videos uploaded to the channel associated with the request. The code also calls the channels.list method with the mine parameter set to true to retrieve the playlist ID that identifies the channel's uploaded videos.

This example uses the Go client library.

package main

import (
	"fmt"
	"log"

	"google.golang.org/api/youtube/v3"
)

// Retrieve playlistItems in the specified playlist
func playlistItemsList(service *youtube.Service, part string, playlistId string, pageToken string) *youtube.PlaylistItemListResponse {
	call := service.PlaylistItems.List(part)
	call = call.PlaylistId(playlistId)
	if pageToken != "" {
		call = call.PageToken(pageToken)
	}
	response, err := call.Do()
	handleError(err, "")
	return response
}

// Retrieve resource for the authenticated user's channel
func channelsListMine(service *youtube.Service, part string) *youtube.ChannelListResponse {
	call := service.Channels.List(part)
	call = call.Mine(true)
	response, err := call.Do()
	handleError(err, "")
	return response
}

func main() {
	client := getClient(youtube.YoutubeReadonlyScope)
	service, err := youtube.New(client)
	
	if err != nil {
		log.Fatalf("Error creating YouTube client: %v", err)
	}

	response := channelsListMine(service, "contentDetails")

	for _, channel := range response.Items {
		playlistId := channel.ContentDetails.RelatedPlaylists.Uploads
		
		// Print the playlist ID for the list of uploaded videos.
		fmt.Printf("Videos in list %s\r\n", playlistId)

		nextPageToken := ""
		for {
			// Retrieve next set of items in the playlist.
			playlistResponse := playlistItemsList(service, "snippet", playlistId, nextPageToken)
			
			for _, playlistItem := range playlistResponse.Items {
				title := playlistItem.Snippet.Title
				videoId := playlistItem.Snippet.ResourceId.VideoId
				fmt.Printf("%v, (%v)\r\n", title, videoId)
			}

			// Set the token to retrieve the next page of results
			// or exit the loop if all results have been retrieved.
			nextPageToken = playlistResponse.NextPageToken
			if nextPageToken == "" {
				break
			}
			fmt.Println()
		}
	}
}
