Google DFP API Client for NodeJS

Basics

Initialize the DFP Instance.

``JavaScript
var Dfp = require('node-google-dfp'),
dfpUser = new Dfp.User(NETWORK_CODE, APP_NAME, VERSION);
`

Next, setup your client settings and your user's OAUTH token information.

`JavaScript
dfpUser.setSettings({
client_id : "YOUR CLIENT ID",
client_secret : "YOUR CLIENT SECRET",
refresh_token : "A REFRESH TOKEN",
redirect_url : "YOUR OAUTH REDIRECT URL"
});
`

You can instance any of DFP's API Services; https://developers.google.com/doubleclick-publishers/docs/start


`JavaScript
dfpUser.getService('LineItemService', function (err, lineItemService) {
if (err) {
return console.error(err);
}

var statement = new DfpClass.Statement('WHERE id = 103207340');

lineItemService.getLineItemsByStatement(statement, function (err, results) {
console.log(results);
});

});
`

If you would like to use a Google Service Account to access DFP, you can do so by creating an instance of the JWT auth client.

`JavaScript
var {JWT} = require('google-auth-library')

var jwtClient = new JWT(
SERVICE_ACCOUNT_EMAIL,
'path/to/key.pem',
null,
['https://www.googleapis.com/auth/dfp']);

dfpUser.setClient(jwtClient)

`

This application requires a working oAuth refresh token to make requests. If you don't include a refresh token you will get an "No refresh token is set" error. If you include a bad token, you'll get an "illegal access" error. Service accounts are not supported.

To setup a refresh token manually, follow Google's instructions for using cURL. The main steps are included below.

* Setup a oAuth "installed application" in the Google Developer Console.

* Create a verification request using this installed application's client ID. (If you miss this step you'll get an authorization_pending error from Google on the next step.) Note that any slashes in a device_code will need to be escaped.

`curl -d "client_id={YOUR_OAUTH_CLIENT_ID}&scope=https://www.googleapis.com/auth/dfp" https://accounts.google.com/o/oauth2/device/code`

{
"device_code" : "ABCD-EFGH4/MEiMYvOO1THXLV_fHGGN8obAgb5XFs1Uctj-QsyYsQk",
"user_code" : "ABCD-EFGH",
"verification_url" : "https://www.google.com/device",
"expires_in" : 1800,
"interval" : 5
}


* Visit the verification_url contained in the verification request response (e.g. https://www.google.com/device) in a browser and type in the user_code provided in the verification response. A verification code will be given as a response.

* Use the provided code and your client ID and secret from the Google oAuth application to create a refresh token.

`curl -d "client_id={YOUR_OAUTH_CLIENT_ID}&client_secret={YOUR_OAUTH_CLIENT_SECRET}&code={YOUR_VERIFICATION_CODE}&grant_type=http://oauth.net/grant_type/device/1.0" https://accounts.google.com/o/oauth2/token`

You can use urn:ietf:wg:oauth:2.0:oob for the redirect URL of non-public apps.
