Google Ads API Java Client Library

This project hosts the Java client library for the various SOAP-Based Ads APIs (AdWords, DFA, and DFP) at Google.

Features

  • Distributed via Maven
  • Uses the SLF4J logging facade to log requests and SOAP messages, allowing you to plug in a concrete logging framework of your choice.
  • Automatic handling of SOAP headers
  • Easy management of credentials, authentication, and session information
  • JavaDoc

Requirements

  • Java 1.5+
  • Maven 3.0+ not required, but recommended

Announcements and updates

For API and client library updates and news, please follow our Google+ Ads Developers page and our Google Ads Developers blog

The "adwords-lib" artifact contains all of the library and utility classes for accessing the AdWords API, but does not support any specific SOAP framework. All client library classes and utilities are in the package or sub-packages of "com.google.api.ads.adwords.lib". To add support for the Apache Axis framework, the "adwords-axis" plugin artifact is also necessary. This artifact also includes autogenerated classes from the AdWords API. They are in the package "com.google.api.ads.adwords.{version}".

Getting started

You have the option to use jars or Maven. While we suggest using Maven, we understand that not all build environments can handle this.

Before you do anything

You will need to register an OAuth2 application to get a valid client ID and secret. See the Using OAuth 2 wiki page for more information.

For using jars

In the releases section download a file like adwords-axis-jars-and-examples-v.vv.vv.tar.gz and extract it.

  1. Modify

You will need to modify the ads.properties file with your settings. This can be moved (not copied) to your home directory as well.

$ vim ads.properties
  1. Import

Import the eclipse project by going to File > Import, then General > Existing projects into workspace and selecting the extracted folder.

  1. Authenticate

Now, generate OAuth2 credentials to be used with other examples. Navigate in your project to src/adwords/axis/auth/GetRefreshToken.java and run the example.

Copy the refresh token into your ads.properties file as you just did with your general settings and client ID/secret when prompted.

  1. Run example

Navigate in your project to src/adwords/axis//basicoperations/GetCampaigns.java and run the example.

For using maven

In the releases section download a file like adwords-axis-maven-and-examples-v.vv.vv.tar.gz and extract it.

  1. Modify

You will need to modify the src/main/resources/ads.properties file with your settings. This can be moved (not copied) to your home directory as well.

$ vim src/main/resources/ads.properties
  1. Import

Import the eclipse project by going to File > Import, then General > Existing projects into workspace and selecting the extracted folder.

  1. Authenticate

Now, generate OAuth2 credentials to be used with other examples. Navigate in your project to src/main/java/adwords/axis/auth/GetRefreshToken.java and run the example.

Copy the refresh token into your src/main/resources/ads.properties file as you just did with your general settings and client ID/secret when prompted.

  1. Run example

Navigate in your project to src/main/java/adwords/axis//basicoperations/GetCampaigns.java and run the example.

Basic usage

The following example is for AdWords and Axis, but the general code applies to all products and frameworks.

// Contains the data classes and service classes.
import com.google.api.ads.adwords.axis.v201309.*;

import com.google.api.ads.adwords.lib.client.AdWordsSession;
import com.google.api.ads.adwords.lib.axis.factory.AdWordsServices;

public static void main(String[] args) throws Exception {
  /**
   * Create an AdWordsSession instance, loading credentials from the 
   * properties file:
   */
  
  // Get an OAuth2 credential.
  Credential credential = new OfflineCredentials.Builder()
      .forApi(OfflineCredentials.Api.AdWords)
      .fromFile()
      .build()
      .generateCredential();
  
  // Construct an AdWordsSession.
  AdWordsSession session = new AdWordsSession.Builder()
      .fromFile()
      .withOAuth2Credential(credential)
      .build();
  
  /**
   * Alternatively, you can specify your credentials in the constructor:
   */
  
  // Get an OAuth2 credential.
  credential = new OfflineCredentials.Builder()
      .forApi(OfflineCredentials.Api.AdWords)
      .withClientSecrets(clientId, clientSecret)
      .withRefreshToken(refreshToken)
      .build()
      .generateCredential();
  
  // Construct an AdWordsSession.
  session = new AdWordsSession.Builder()
      .withDeveloperToken(developerToken)
      // ...
      .withOAuth2Credential(credential)
      .build();
  
  /**
   * Instantiate the desired service class using the AdWordsServices utility and a 
   * Class object representing your service.
   */
  
  // Get the CampaignService.
  CampaignServiceInterface campaignService =
      new AdWordsServices().get(session, CampaignServiceInterface.class);
  
  /**
   * Create data objects and invoke methods on the service class instance. The
   * data objects and methods map directly to the data objects and requests for
   * the corresponding web service.
   */
  
  // Create selector.
  Selector selector = new Selector();
  selector.setFields(new String[] {"Id", "Name"});
  
  // Get all campaigns.
  CampaignPage page = campaignService.get(selector);
}

How do I enable logging?

The client library uses SLF4J for all logging. If you want to turn logging on, you must include a plugin that bridges SLF4J with a concrete logging framework. To quickly get you started and to serve as an example of how to do this, this example distribution uses the log4j framework.

There are the following loggers within the library:

  • com.google.api.ads.adwords.lib.client.AdWordsServiceClient.soapXmlLogger com.google.api.ads.dfa.lib.client.DfaServiceClient.soapXmlLogger com.google.api.ads.dfp.lib.client.DfpServiceClient.soapXmlLogger

    Logs incoming and outgoing SOAP requests/responses. SOAP requests and responses are logged as WARN for exceptions and INFO for all other requests. You can configure your logging framework to accept logs on these parameters. See the example log4j.properties for more information.

  • com.google.api.ads.adwords.lib.client.AdWordsServiceClient.requestInfoLogger com.google.api.ads.dfa.lib.client.DfaServiceClient.requestInfoLogger com.google.api.ads.dfp.lib.client.DfpServiceClient.requestInfoLogger

    Logs all requests from the client library along with information such as the timestamp, service, method, endpoint URL.

Because the client library uses SLF4J, the behavior of these loggers is highly customizable. Please see the "log4j.properties" or "src/main/resources/log4j.properties" file for details on the default behavior in this example project.

If you are using jars

To use a different framework than log4j, remove the slf4j-log4j12 jar from your classpath and fetch a different one here: http://www.slf4j.org/download.html

If you are using maven

To bridge SLF4J for a logging framework, you must do the following:

  1. Include the plugin and logging framework dependencies in the pom.xml file's dependencies list.

    log4j log4j 1.2.16 org.slf4j slf4j-log4j12 1.6.2
  2. If your logging framework requires a configuration file, you must place it in the resources directory. This distribution includes an example configuration for log4j named "log4j.properties".

Using a proxy

It is recommended that the user set JVM arguments to configure this application for their proxy.

https.proxyHost      Hostname of proxy server                      web-proxy
https.proxyPort      Port on server of proxy                       8080
https.proxyUser      Optional username for proxy authentication    someone
https.proxyPassword  Optional proxy server password                secret

These properties can be set with java args in your eclipse run configuration:

-Dhttps.proxyHost=web-proxy -Dhttps.proxyPort=8080 -Dhttps.proxyUser=someone 
-Dhttps.proxyPassword=secret ...

If necessary, set this up in code by doing the following:

System.setProperty("https.proxyHost", "web-proxy");
System.setProperty("https.proxyPort", "8080");
System.setProperty("https.proxyUser", "someone");
System.setProperty("https.proxyPassword", "secret");
