Use\n [this wizard](https://console.developers.google.com/start/api?id=youtube)\n to create or select a project in the Google Developers Console and\n automatically turn on the API. Click **Continue** , then\n **Go to credentials**.\n\n2. On the **Create credentials** page, click the\n **Cancel** button.\n\n3. At the top of the page, select the **OAuth consent screen** tab.\n Select an **Email address** , enter a **Product name** if not\n already set, and click the **Save** button.\n\n4. Select the **Credentials** tab, click the **Create credentials**\n button and select **OAuth client ID**.\n\n5. Select the application type **Other** , enter the name\n \"YouTube Data API Quickstart\", and click the **Create** button.\n\n6. Click **OK** to dismiss the resulting dialog.\n\n7. Click the file_download\n (Download JSON) button to the right of the client ID.\n\n8. Move the downloaded file to your working directory and rename it\n `client_secret.json`.\n\nStep 2: Install the client library\n----------------------------------\n\nRun the following commands to install the libraries using npm: \n\n npm install googleapis --save\n npm install google-auth-library --save\n\nStep 3: Set up the sample\n-------------------------\n\nCreate a file named `quickstart.js` in your working directory and copy in\nthe following code:\n\n\n```javascript\nvar fs = require('fs');\nvar readline = require('readline');\nvar {google} = require('googleapis');\nvar OAuth2 = google.auth.OAuth2;\n\n// If modifying these scopes, delete your previously saved credentials\n// at ~/.credentials/youtube-nodejs-quickstart.json\nvar SCOPES = ['https://www.googleapis.com/auth/youtube.readonly'];\nvar TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||\n process.env.USERPROFILE) + '/.credentials/';\nvar TOKEN_PATH = TOKEN_DIR + 'youtube-nodejs-quickstart.json';\n\n// Load client secrets from a local file.\nfs.readFile('client_secret.json', function processClientSecrets(err, content) {\n if (err) {\n console.log('Error loading client secret file: ' + err);\n return;\n }\n // Authorize a client with the loaded credentials, then call the YouTube API.\n authorize(JSON.parse(content), getChannel);\n});\n\n/**\n * Create an OAuth2 client with the given credentials, and then execute the\n * given callback function.\n *\n * @param {Object} credentials The authorization client credentials.\n * @param {function} callback The callback to call with the authorized client.\n */\nfunction authorize(credentials, callback) {\n var clientSecret = credentials.installed.client_secret;\n var clientId = credentials.installed.client_id;\n var redirectUrl = credentials.installed.redirect_uris[0];\n var oauth2Client = new OAuth2(clientId, clientSecret, redirectUrl);\n\n // Check if we have previously stored a token.\n fs.readFile(TOKEN_PATH, function(err, token) {\n if (err) {\n getNewToken(oauth2Client, callback);\n } else {\n oauth2Client.credentials = JSON.parse(token);\n callback(oauth2Client);\n }\n });\n}\n\n/**\n * Get and store new token after prompting for user authorization, and then\n * execute the given callback with the authorized OAuth2 client.\n *\n * @param {google.auth.OAuth2} oauth2Client The OAuth2 client to get token for.\n * @param {getEventsCallback} callback The callback to call with the authorized\n * client.\n */\nfunction getNewToken(oauth2Client, callback) {\n var authUrl = oauth2Client.generateAuthUrl({\n access_type: 'offline',\n scope: SCOPES\n });\n console.log('Authorize this app by visiting this url: ', authUrl);\n var rl = readline.createInterface({\n input: process.stdin,\n output: process.stdout\n });\n rl.question('Enter the code from that page here: ', function(code) {\n rl.close();\n oauth2Client.getToken(code, function(err, token) {\n if (err) {\n console.log('Error while trying to retrieve access token', err);\n return;\n }\n oauth2Client.credentials = token;\n storeToken(token);\n callback(oauth2Client);\n });\n });\n}\n\n/**\n * Store token to disk be used in later program executions.\n *\n * @param {Object} token The token to store to disk.\n */\nfunction storeToken(token) {\n try {\n fs.mkdirSync(TOKEN_DIR);\n } catch (err) {\n if (err.code != 'EEXIST') {\n throw err;\n }\n }\n fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) =\u003e {\n if (err) throw err;\n console.log('Token stored to ' + TOKEN_PATH);\n });\n}\n\n/**\n * Lists the names and IDs of up to 10 files.\n *\n * @param {google.auth.OAuth2} auth An authorized OAuth2 client.\n */\nfunction getChannel(auth) {\n var service = google.youtube('v3');\n service.channels.list({\n auth: auth,\n part: 'snippet,contentDetails,statistics',\n forUsername: 'GoogleDevelopers'\n }, function(err, response) {\n if (err) {\n console.log('The API returned an error: ' + err);\n return;\n }\n var channels = response.data.items;\n if (channels.length == 0) {\n console.log('No channel found.');\n } else {\n console.log('This channel\\'s ID is %s.

Browse to the provided URL in your web browser.\n\n If you are not already logged into your Google account, you will be\n prompted to log in. If you are logged into multiple Google accounts, you\n will be asked to select one account to use for the authorization.\n2. Click the **Accept** button.\n3. Copy the code you're given, paste it into the command-line prompt, and press **Enter**.\n\nIt worked! **Great!** Check out the further reading section below to learn more.\nI got an error **Bummer.** Thanks for letting us know and we'll work to fix this quickstart.\n\nNotes\n-----\n\n- Authorization information is stored on the file system, so subsequent executions will not prompt for authorization.\n- The authorization flow in this example is designed for a command line application.
