An SDK built to facilitate application development for Facebook Ads API.

Facebook Ads API SDK for PHP

This Ads API SDK is built to facilitate application development for Facebook Ads API.

Installation

The Facebook Ads API SDK requires PHP 5.4 or greater.

Composer

Facebook Ads API SDK uses composer to manage dependencies. You can follow this document to install composer.

Add the following to your composer.json file:

{
    "require": {
        "facebook/php-ads-sdk": "2.5.*"
    }
}

then install it through composer:

php composer.phar install --no-dev

This SDK and its dependencies will be installed under ./vendor.

Alternatives

This repository is written following the psr-4 autoloading standard. Any psr-4 compatible autoloader can be used.

Usage

Api main class

The FacebookAds\Api object is the foundation of the Ads SDK which encapsulates a FacebookAds\Session and is used to execute requests against the Graph API.

To instantiate an Api object you will need a valid access token:

use FacebookAds\Api;

// Initialize a new Session and instanciate an Api object
Api::init($app_id, $app_secret, $access_token);

// The Api object is now available trough singleton
$api = Api::instance();

Once instantiated, the Api object will allow you to start making requests to the Ads API.

Fields names

Due to the high number of field names in the Ads API existing objects, in order to facilitate your code maintainability, enum-like classes are provided. These files are stored under the FacebookAds/Object/Fields directory. You can access object properties in the same manner you would usually do in php:

use FacebookAds\Object\AdAccount;

$account = new AdAccount();
$account->name = 'My account name';
echo $account->name;

or using the enums:

use FacebookAds\Object\AdAccount;
use FacebookAds\Object\Fields\AdAccountFields;

$account = new AdAccount();
$account->{AdAccountFields::NAME} = 'My account name';
echo $account->{AdAccountFields::NAME};

Object classes

Facebook Ads entities are defined as classes under the FacebookAds/Object directory.

Read Objects

use FacebookAds\Object\AdAccount;

$account = new AdAccount($account_id);
$account->read();

For some objects, the Ads API doesn't return all available fields by default. The first argument of the object's read method is an array of field names to be requested.

use FacebookAds\Object\AdAccount;
use FacebookAds\Object\Fields\AdAccountFields;

$fields = array(
  AdAccountFields::ID,
  AdAccountFields::NAME,
  AdAccountFields::DAILY_SPEND_LIMIT,
);

$account = new AdAccount($account_id);
$account->read($fields);

Requesting an high number of fields may cause the response time to visibly increase, you should always request only the fields you really need.

Create Objects

use FacebookAds\Object\AdSet;
use FacebookAds\Object\Fields\AdSetFields;

$account_id = 'act_123123';
$campaign_id = '123456';

$set = new AdSet(null, $account_id);
$set->setData(array(
  AdSetFields::NAME => 'My Test AdSet',
  AdSetFields::CAMPAIGN_ID => $campaign_id,
  AdSetFields::DAILY_BUDGET => 150,
  AdSetFields::START_TIME => (new \DateTime("+1 week"))->format(\DateTime::ISO8601),
  AdSetFields::END_TIME => (new \DateTime("+2 week"))->format(\DateTime::ISO8601),
));
$set->create(array(
  AdSet::STATUS_PARAM_NAME => AdSet::STATUS_PAUSED,
));
echo $set->id;

Update Objects

use FacebookAds\Object\AdSet;
use FacebookAds\Object\Fields\AdSetFields;

$ad_set_id = '123456';

$set = new AdSet($ad_set_id);
$set->{AdSetFields::NAME} = 'My new AdSet name';
$set->update();

Delete Objects

use FacebookAds\Object\AdSet;

$ad_set_id = '123456';

$set = new AdSet($ad_set_id);
$set->delete();

Cursors

Since the release of the Facebook Graph API 2.0, pagination is handled through cursors. Here cursors are defined as in \FacebookAds\Cursor. Cursors are generally returned from connection methods:

use FacebookAds\Object\AdAccount;
use FacebookAds\Object\Fields\CampaignFields;

$account = new AdAccount('<ACT_ID>');
$cursor = $account->getCampaigns();

// Loop over objects
foreach ($cursor as $campaign) {
  echo $campaign->{CampaignFields::NAME}.PHP_EOL;
}

// Access objects by index
if ($cursor->count() > 0) {
  echo "The first campaign in the cursor is: ".$cursor[0]->{CampaignFields::NAME}.PHP_EOL;
}

// Fetch the next page
$cursor->fetchAfter();
// New Objects will be appended to the cursor

Implicit Fetching

Whenever all object connected to a parent are required (carelessly from the number of HTTP requests) implicit fetching can help reducing the amount of code required. If cursor has Implicit Fetching enabled, while iterating (foreach, Cursor::next(), Cursor::prev()) the page end is reached, the SDK will automatically fetch and append a new page, untill cursor end. Implicit Fetching will make you lose controll of the number of HTTP request that will be sent and, for this reason, is disabled by default. Implicit Fetching can be enabled for a specific cursor:

$cursor->setUseImplicitFetch(true);

Or globally:

use FacebookAds\Cursor;

Cursor::setDefaultUseImplicitFetch(true);

Reverse Iterations

Cursors are bi-directional, and can be iterated in reverse order:

use FacebookAds\Object\AbstractCrudObject;

/** @var \FacebookAds\Cursor $cursor */
$cursor->setUseImplicitFetch(true);

$cursor->end();
while ($cursor->valid()) {
  echo $cursor->current()->{AbstractCrudObject::FIELD_ID}.PHP_EOL;
  $cursor->prev();
}

Tests

The 'test' folder contains the test cases. These are logically divided in unit and integration tests. Integration tests require an active Facebook Ad Account, a Facebook Application and a valid Access Token.

Note: we are currently unable to securely and reliably run integration tests on a public CI system. Our integrations with Travis and Scrutinizer (including badges at the top of this file) include only unit tests.

Install dependencies

From the root folder run:

php composer.phar install --dev

Execute unit tests only

./vendor/bin/phpunit -c test/phpunit-travis.xml

To run tests individually (be sure not to be pointing to an integration test file):

./vendor/bin/phpunit -c test/phpunit-travis.xml path/to/class/file

Execute all tests (unit + integration)

Setup your integration config:

1 - Copy the config file template.

cp test/config.php.dist test/config.php

2 - Edit test/config.php with your informations.

Execute:

./vendor/bin/phpunit -c test/

To run tests individually:

./vendor/bin/phpunit -c test/ path/to/class/file
