Google Ads APIs Client Library for Java

This project hosts the client library for Java for the various SOAP-based ads APIs (AdWords and Ad Manager) 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 1.8+
Maven 3.0+ not required, but recommended

Maven artifacts

AdWords

    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>ads-lib</artifactId>
      <version>RELEASE</version>
    </dependency>
    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>adwords-axis</artifactId>
      <version>RELEASE</version>
    </dependency>

Ad Manager

    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>ads-lib</artifactId>
      <version>RELEASE</version>
    </dependency>
    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>dfp-axis</artifactId>
      <version>RELEASE</version>
    </dependency>

Note: The following explanation is for AdWords and Axis, but the general idea applies to all products and frameworks.

The ads-lib artifact contains all of the library and utility classes for accessing the Ads 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.common.lib. To add support for the AdWords API using 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

Configure your project. You have multiple options for this step. While we suggest using Maven, we understand that not all build environments can handle this.
- If using Maven with Eclipse
  
  In the releases section download a file like adwords-axis-maven-and-examples-v.vv.vv.tar.gz and extract its contents to a directory.
  
  Import the Eclipse project by going to File > Import, then General > Existing projects into workspace and selecting the extracted folder.
- If using Maven from the command line
  
  In the releases section download a file like adwords-axis-maven-and-examples-v.vv.vv.tar.gz and extract its contents to a directory.
- If using jars
  
  In the releases section download a file like adwords-axis-jars-and-examples-v.vv.vv.tar.gz and extract its contents to a directory.
Copy the sample ads.properties file to your home directory and fill out the required properties. You can skip the properties ending with clientId, clientSecret, and refreshToken for now. You'll set those in the next step.
- AdWords ads.properties
- Ad Manager ads.properties
Setup your OAuth2 credentials.

The AdWords and Ad Manager APIs use OAuth2 as the authentication mechanism. Follow the appropriate guide below based on your use case.

If you're accessing an API using your own credentials...
- Using AdWords
- Using Ad Manager
If you're accessing an API on behalf of clients...
- Developing a web application (AdWords or Ad Manager)
Run an example.
- If using Maven with Eclipse
  
  Navigate in your project to any example (e.g., src/main/java/adwords/axis/v201809/basicoperations/GetCampaigns.java) and run the example.
- If using Maven from the command line
  
  This command runs the GetAdGroups example, but you can update the -Dexec.mainClass argument with the example of your choice.
  
  Any parameters required for an example to run can be passed on the command line by using -Dexec.args. To see more information about a particular example, use -Dexec.args="--help".
```
$ mvn -X exec:java -Dexec.mainClass="adwords.axis.v201809.basicoperations.GetAdGroups" -Dexec.args="--campaignId YOUR_CAMPAIGN_ID"
```
- If using jars
  
  Navigate in your project to any example (e.g., src/adwords/axis/v201809/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.v201809.*;

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. Check out our logging guide on github for more details.

How do I enable compression?

First, add an entry to your ads.properties file for each API you plan to use.

# AdWords
api.adwords.useCompression=true
# Ad Manager 
api.admanager.useCompression=true

If using JaxWs, then no further steps are required.

If using Axis, then no further steps are required unless you are setting the axis.ClientConfigFile system property. If you are setting axis.ClientConfigFile to your own custom WSDD file and you want to use compression, please ensure that the http transport defined in your WSDD supports compression.

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 JVM arguments 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");
