Google Ads API PHP Client Library

This project hosts the PHP client library for the various SOAP-based Ads APIs (AdWords and DFP) at Google.

Welcome to the new ads API PHP client library!

The ads API PHP client library has been rewritten. If you're new to this library, read on! If you're already using our library, you may want to take a look at our Upgrading guide first.

Getting started

Install the latest version using Composer.

$ php composer.phar require googleads/googleads-php-lib

Copy the sample adsapi_php.ini for your product to your home directory and fill out the required properties.
- AdWords adsapi_php.ini
- DFP adsapi_php.ini
Set up your OAuth2 credentials.

The AdWords and DoubleClick for Publishers 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 DFP
If you're accessing an API on behalf of clients...
- Using AdWords or DFP

Running examples

You have two ways of getting example files: using git clone or downloading a compressed tarball.

Using git clone

This method is suitable for those who want to alter or contribute to this library. All files in this repository will be downloaded.

Run git clone https://github.com/googleads/googleads-php-lib.git in your command prompt.
You will get a googleads-php-lib directory. Navigate to it by running cd googleads-php-lib.
Run php composer.phar install. This will install all dependencies needed for running examples.
Set up your adsapi_php.ini file if you've not done so. See steps 2 and 3 in Getting Started for detail.
You can now run any examples you want. Try GetCampaigns.php by executing the following command:
```
$ php examples/AdWords/v201705/BasicOperations/GetCampaigns.php
```

Downloading a compressed tarball

This is suitable for those who only want to try out the AdWords API with this client library. The extracted directory of the tarball will contain only the examples/ directory.

In the releases page, select a version you want to try. Then, under Download, you can see the names of compressed tarballs for AdWords and DFP. Click on the name of compressed tarball you want to try, e.g., adwords-examples-vX.Y.Z.tar.gz for AdWords.
Extract your downloaded file to any location in your computer.
Change to the extracted directory (such as adwords-examples-vX.Y.Z).
Follow all the steps in the README.md file in the directory, including running php composer.phar install and setting up adsapi_php.ini.
You can now run any examples you want. Try GetCampaigns.php by executing the following command:
```
$ php examples/AdWords/v201705/BasicOperations/GetCampaigns.php
```

Basic usage

The best way to learn how to use this library is to review the examples for your product.

All our examples are meant to be run via the command line and not through a webpage.

If you're using 32-bit PHP, you'll need to change all instances of intval() to floatval() before running an example. This is due to some IDs exceeding the 32-bit PHP_INT_MAX that intval() changes your value to. In addition, when writing your own code, do not apply intval() on any attributes that are explicitly an integer.

The following snippet of code from the BasicOperations/GetCampaigns.php example for AdWords gives you an idea of how to use this library. The usage pattern is similar for DFP.

use Google\AdsApi\AdWords\AdWordsServices;
use Google\AdsApi\AdWords\AdWordsSessionBuilder;
use Google\AdsApi\AdWords\v201705\cm\CampaignService;
use Google\AdsApi\AdWords\v201705\cm\OrderBy;
use Google\AdsApi\AdWords\v201705\cm\Paging;
use Google\AdsApi\AdWords\v201705\cm\Selector;
use Google\AdsApi\Common\OAuth2TokenBuilder;

$oAuth2Credential = (new OAuth2TokenBuilder())
    ->fromFile()
    ->build();

$session = (new AdWordsSessionBuilder())
    ->fromFile()
    ->withOAuth2Credential($oAuth2Credential)
    ->build();

$adWordsServices = new AdWordsServices();

$campaignService = $adWordsServices->get($session, CampaignService::class);

// Create selector.
$selector = new Selector();
$selector->setFields(array('Id', 'Name'));
$selector->setOrdering(array(new OrderBy('Name', 'ASCENDING')));

// Create paging controls.
$selector->setPaging(new Paging(0, 100));

// Make the get request.
$page = $campaignService->get($selector);

// Do something with the $page.

The builder's fromFile() method looks for an adsapi_php.ini file in your home directory by default. If you want to store this file in another directory, pass the path of the file as an argument. For example:

fromFile('/config/myprops.ini')

It is highly recommended that you use an adsapi_php.ini file. However, if you don't want to or can't use one, you can use the OAuth2 token and ads session builders instead to set the same information. See the builders for details:

WSDL objects with names that are reserved PHP keywords

Class names

Note that some WSDL object types have names that are reserved PHP keywords and need to be augmented when used as PHP class names. The following is a list of these occurences.

Function => MatchingFunction
Parent => ParentCriterion

Constant names

Some WSDL enum values have names that are reserved PHP keywords and need to be modified when used as PHP constant names. For example, AND and DEFAULT are generated as AND_VALUE and DEFAULT_VALUE.

Logging

This library conforms to PSR-3 for logging and provides the following loggers:

AdWords

SOAP logger
Report downloader logger
Batch jobs utility logger

DFP

SOAP logger
Report downloader logger

In general, each logger logs a summary and debug message for events (e.g., a SOAP API call). The level at which messages are logged depends on whether the event succeeded.

Log message \ Event status	Success	Failure
One-line summary	INFO	WARNING
Debug message (e.g., SOAP payload)	DEBUG	NOTICE

Configuring logging

By default, each of the library loggers logs to STDERR on a separate channel using a Monolog StreamHandler.

You can configure some options for these default loggers in the adsapi_php.ini file:

[LOGGING]
; Optional logging settings.
soapLogFilePath = "path/to/your/soap.log"
soapLogLevel = "NOTICE"

If you need to further customize logging, you can specify your own logger entirely by providing a logger that implements LoggerInterface in either the AdWords or DFP session builders:

$session = (new AdWordsSessionBuilder())
    ...
    ->withSoapLogger(new MyCustomSoapLogger())
    ->withReportDownloaderLogger(new MyCustomReportDownloaderLogger())
    ->build();

Reporting

When downloading reports, you can set additional stream context options using the stream_context key to suit your needs (e.g., increasing the timeout as shown below). See also Guzzle FAQ for details.

$options = [
    'stream_context' => [
        'http' => ['timeout' => 120]
    ]
];
$requestOptionsFactory = new RequestOptionsFactory($session, $options);
$reportDownloader = new ReportDownloader($session, $requestOptionsFactory);

SSL CA files

PHP >= v5.6 automatically sets verify_peer to true and will do its best to find the most appropriate CA bundle on your system by default. However, not all systems have a known CA bundle on disk (e.g. Windows). This library tries to locate CA bundles on your system by using Guzzle default_ca_bundle().

If this library can't find CA bundle on your system, you will get this error message:

cURL error 60: SSL certificate problem: unable to get local issuer certificate".

To resolve this, manually specify your SSL CA file location with SoapSettinsBuilder's withSslCaFile().
