We recommend using the client library with Apache Maven (or Gradle).
Create a new Maven/Gradle project
Create a new Maven/Gradle project in the IDE of you choice. Our artifacts are published to the Maven central repository.
The Maven dependency is:
<dependency> <groupId>com.google.api-ads</groupId> <artifactId>google-ads</artifactId> <version>21.0.0</version> </dependency>
The Gradle dependency is:
You may also build from source. For the purpose of this guide we'll assume that you have a project setup with the required dependencies available.
Obtain credentials to authenticate with the API
Access to the Google Ads API requires OAuth credentials and a Google Ads API developer token. This section explains what these are, how they're used and how they're obtained.
Developer token (for access to the API)
OAuth credentials (for access to Google Ads accounts)
To authorize as Google account users with access to Google Ads accounts, you must provide a set of OAuth credentials.
There are two OAuth flows that are generally used: desktop (installed) app or web app. The main difference between the two is that desktop apps must open the system browser and supply a local redirect URI to handle responses from Google's authorization server, whereas web apps can redirect an arbitrary third-party browser to complete authorization and send the credentials back to your server. The library also supports the less commonly used service account flow.
- If you authorize using your own credentials (desktop app flow)
- Refer to the OAuth desktop app flow. This includes all the details you need for authorizing with your own credentials.
- If you authorize as a third-party Google user (web flow)
- Refer to the OAuth web app flow. This gives an example of how to set up OAuth authorization for arbitrary third-party users.
- If you authorize as a Google Apps Domain user (service account flow)
- Refer to the OAuth service account flow. This gives an example of how to set up OAuth authorization for Google Apps Domain users.
If your access to the Google Ads customer account is through a Google Ads manager account, you must also specify a login customer ID as described below.
Login customer ID (for access to Google Ads accounts through a manager account)
Optionally, specify the customer ID of a manager account which gives access to the serving account. This must be specified if your access to the customer account is through a manager account. There is no need to specify all manager accounts on the path to the customer ID, only the topmost manager ID which you are using for access permissions. For more details, see the related documentation.
Configure the client library with your credentials
You can either configure the client library with a configuration file, environment variables, or programmatically. For this guide, we'll use the configuration file approach and focus on the desktop and web flows. Using a configuration file is generally a good approach if you only have one set of credentials (for example, you manage accounts under a single manager).
Create a file
~/ads.properties with the following content:
api.googleads.clientId=INSERT_CLIENT_ID_HERE api.googleads.clientSecret=INSERT_CLIENT_SECRET_HERE api.googleads.refreshToken=INSERT_REFRESH_TOKEN_HERE api.googleads.developerToken=INSERT_DEVELOPER_TOKEN_HERE
Replace the placeholders with your credentials obtained in the previous step.
Additionally, if your refresh token is for a manager account, you should specify the customer ID of this account as the login customer:
Validate the credentials
To ensure that everything is setup correctly, we'll run the GetCampaigns example.
First, navigate into the
$ cd google-ads-examples
This example requires a
--customerId parameter where the value is your
Google Ads account customer ID without dashes.
To run with Gradle:
$ ./gradlew -q runExample --example="basicoperations.GetCampaigns --customerId INSERT_CUSTOMER_ID_HERE"
Explore other examples
The examples package in
contains several useful examples. Most of the examples require
parameters. You can either pass the parameters as arguments (recommended) or
INSERT_XXXXX_HERE values in the source code. To see a usage statement
for an example, pass
--help as the only argument.
$ ./gradlew -q runExample --example="basicoperations.GetCampaigns --help" $ ./gradlew -q runMigrationExample --example="campaignmanagement.CreateCompleteCampaignGoogleAdsApiOnly --help"
