I am trying to create a new broadcast using google-api-ruby-client

YT = Google::Apis::YoutubeV3
client = YT::YouTubeService.new
client.key = 'my-api-key-here'
metadata = {
  snippet: {
    title: 'test',
    scheduled_start_time: '2018-02-23T14:50:00.000Z'
  },
  status: {
    privacy_status: 'public'
  }
}
part = 'snippet'
client.insert_live_broadcast(part, metadata, {})

When I execute this code I am getting Error -# <Google::Apis::AuthorizationError: Unauthorized>

[5] pry(main)> CreateYoutubeBroadcast.execute

Caught error Unauthorized
Error - #<Google::Apis::AuthorizationError: Unauthorized>

Retrying after authentication failure
Google::Apis::AuthorizationError: Unauthorized

I have done

Any idea why this error is occurring? Thank you

It seems creating scheduled broadcasts is not possible via API keys, I used google OAuth 2.0 strategy to get this done.

# lib/youtube_api/o_auth_client.rb

require 'google/api_client/auth/storage'
require 'google/api_client/auth/storages/file_store'
require 'google/api_client/auth/installed_app'

module YoutubeApi
  class OAuthClient
    YOUTUBE_SCOPE = 'https://www.googleapis.com/auth/youtube'
    CREDENTIALS_FILE = Rails.root.join('tmp', 'google_api_credentials.json')

    def initialize
      @credentials_storage = ::Google::APIClient::Storage.new(
        ::Google::APIClient::FileStore.new(CREDENTIALS_FILE)
      )
    end

    def authorize
      @credentials_storage.authorize || begin
        installed_app_flow = ::Google::APIClient::InstalledAppFlow.new(
          client_id:     Rails.application.secrets.youtube_client_id,
          client_secret: Rails.application.secrets.youtube_client_secret,
          scope:         [YOUTUBE_SCOPE]
        )
        installed_app_flow.authorize(@credentials_storage)
      end
    end
  end
end

and my create_broadcast service object

require 'service'
require 'youtube_api'
require 'google/apis/youtube_v3'


class CreateBroadcast
  include Service

  YT = Google::Apis::YoutubeV3
  BROADCAST_PRIVACY = 'public'

  def initialize(title, description, start_time)
    @client = YT::YouTubeService.new
    @client.authorization = YoutubeApi.authorize_via_google_oauth_2
    @title = title
    @description = description
    @start_time = start_time
  end

  def execute
    @client.insert_live_broadcast(part, metadata, {})
  end

  private

    def part
      'id,snippet,contentDetails,status'
    end

    def metadata
      {
        snippet: {
          title: @title,
          description: @description,
          scheduled_start_time: @start_time,
        },
        status: {
          privacy_status: BROADCAST_PRIVACY
        }
      }
    end
end

and in lib/youtube_api.rb I have

# frozen_string_literal: true

require 'youtube_api/o_auth_client'

module YoutubeApi
  def self.authorize_via_google_oauth_2
    oauth_client = OAuthClient.new
    oauth_client.authorize
  end
end
