Facebook api – Facebook Marketing API (php SDK) 'invalid parameter' for AdCreative

I’m trying to get the Marketing API examples work with PHP SDK. I’ve managed to create a Campaign, to set targeting, upload an image and create AdSet. However, I’m having trouble with the AdCreative and the Ad itself.

The code keeps breaking with ‘Invalid Parameter’, but I don’t know which one is the invalid one. I’ve been debugging for 3 days now and I’m stuck. Here’s the code I have:

Creates the Campaign:

$campaign = new Campaign(null, 'act_xxxxxxx');
$campaign->setData(array(
  CampaignFields::NAME => '#My Campaign#',
  CampaignFields::OBJECTIVE => CampaignObjectiveValues::LINK_CLICKS,
));

$campaign->create(array(
  Campaign::STATUS_PARAM_NAME => Campaign::STATUS_PAUSED,
));

Create target audience:

$targeting = new Targeting();
$targeting->{TargetingFields::GEO_LOCATIONS} =
  array(
    'location_types' => array('recent'),
    'custom_locations' => array(
                            array(
                                'latitude'=> 'xx.xxxxxxx',
                                 'longitude'=> 'xx.xxxxxxx',
                                  'radius'=> 2,
                                   'distance_unit'=> 'kilometer')),
  );

Create Adset:

$start_time = (new DateTime("+1 day"))->format(DateTime::ISO8601);
$end_time = (new DateTime("+2 day"))->format(DateTime::ISO8601);

$adset = new AdSet(null, 'act_xxxxxxxx');
$adset->setData(array(
  AdSetFields::NAME => '#My Adset#',
  AdSetFields::OPTIMIZATION_GOAL => AdSetOptimizationGoalValues::LINK_CLICKS,
  AdSetFields::BILLING_EVENT => AdSetBillingEventValues::LINK_CLICKS,
  AdSetFields::BID_AMOUNT => 2,
  AdSetFields::DAILY_BUDGET => 500,
  AdSetFields::CAMPAIGN_ID => $campaign->id,
  AdSetFields::TARGETING => $targeting,
  AdSetFields::START_TIME => $start_time,
  AdSetFields::END_TIME => $end_time,
));
$adset->create(array(
  AdSet::STATUS_PARAM_NAME => AdSet::STATUS_PAUSED,
));

Upload the image:

$image = new AdImage(null, 'act_xxxxxxxx');
$image->{AdImageFields::FILENAME} = 'fb-ad-images/xxxxx.jpeg';

$image->create();
$img_hash=$image->{AdImageFields::HASH}.PHP_EOL;

Creates the AdCreative:

$link_data = new AdCreativeLinkData();
$link_data->setData(array(
  AdCreativeLinkDataFields::MESSAGE => 'try it out',
  AdCreativeLinkDataFields::LINK => 'http://example.com',
  AdCreativeLinkDataFields::CAPTION => 'My caption',
  AdCreativeLinkDataFields::IMAGE_HASH => $img_hash,
));

$object_story_spec = new AdCreativeObjectStorySpec();
$object_story_spec->setData(array(
  AdCreativeObjectStorySpecFields::PAGE_ID => xxxxxxxxxxxxxxx,
  AdCreativeObjectStorySpecFields::LINK_DATA => $link_data,
));

$creative = new AdCreative(null, 'act_xxxxxxx');

$creative->setData(array(
  AdCreativeFields::NAME => 'Sample Creative',
  AdCreativeFields::OBJECT_STORY_SPEC => $object_story_spec,
));

$creative->create();

Creates the Ad:

$data = array(
  AdFields::NAME => 'My Ad',
  AdFields::ADSET_ID => $adset->id,
  AdFields::CREATIVE => array(
    'creative_id' => $creative->id,
  ),
);

$ad = new Ad(null, 'act_xxxxxx');
$ad->setData($data);
$ad->create(array(
  Ad::STATUS_PARAM_NAME => Ad::STATUS_PAUSED,
));

I’ve checked the validation compatibility of the parameters and all seems ok. The error is

Fatal error: Uncaught exception 'FacebookAdsHttpExceptionAuthorizationException' with message 'Invalid parameter'

Can anyone please help, I’m really stuck. Thanks.

    Looking at your code, it looks like you weren’t specifying the longititude and latitude in the Targeting. The xx.xxx needs to be replaced with text. The way I figured that out is by enabling logging in the code and getting the actual API calls which indicated the error. Take a look at the updated code snippet. 

    <?php
$access_token = '<ACCESS_TOKEN>';
$app_id = <APP_ID>;
$app_secret = '<APP_SECRET>';
// should begin with "act_" (eg: $account_id = 'act_1234567890';)
$account_id = 'act_<Ad_ACCOUNT_ID>';
// Configurations - End

if (is_null($access_token) || is_null($app_id) || is_null($app_secret)) {
  throw new Exception(
    'You must set your access token, app id and app secret before executing'
  );
}

if (is_null($account_id)) {
  throw new Exception(
    'You must set your account id before executing');
}

define('SDK_DIR', __DIR__ . '/..'); // Path to the SDK directory
$loader = include SDK_DIR.'/vendor/autoload.php';

use FacebookAdsApi;
use FacebookAdsLoggerCurlLogger;
Api::init($app_id, $app_secret, $access_token);

// Create the CurlLogger
$logger = new CurlLogger();
// To write to a file pass in a file handler
// $logger = new CurlLogger(fopen('test','w'));
// Attach the logger to the Api instance
Api::instance()->setLogger($logger);

use FacebookAdsObjectCampaign;
use FacebookAdsObjectFieldsCampaignFields;
use FacebookAdsObjectValuesCampaignObjectiveValues;
use FacebookAdsObjectTargeting;
use FacebookAdsObjectFieldsTargetingFields;
use FacebookAdsObjectFieldsAdSetFields;
use FacebookAdsObjectAdSet;
use FacebookAdsObjectValuesAdSetOptimizationGoalValues;
use FacebookAdsObjectValuesAdSetBillingEventValues;

$campaign = new Campaign(null, $account_id);
$campaign->setData(array(
  CampaignFields::NAME => '#My Campaign#',
  CampaignFields::OBJECTIVE => CampaignObjectiveValues::LINK_CLICKS,
));

$campaign->create(array(
  Campaign::STATUS_PARAM_NAME => Campaign::STATUS_PAUSED,
));

$targeting = new Targeting();
$targeting->{TargetingFields::GEO_LOCATIONS} =
  array(
    'location_types' => array('recent'),
    'custom_locations' => array(
                            array(
                                'latitude'=> '47.6062',
                                 'longitude'=> '122.3321',
                                  'radius'=> 2,
                                   'distance_unit'=> 'kilometer')),
  );

$start_time = (new DateTime("+1 day"))->format(DateTime::ISO8601);
$end_time = (new DateTime("+2 day"))->format(DateTime::ISO8601);
echo $campaign->id."n";
$adset = new AdSet(null, $account_id);
$adset->setData(array(
  AdSetFields::NAME => '#My Adset#',
  AdSetFields::OPTIMIZATION_GOAL => AdSetOptimizationGoalValues::IMPRESSIONS,
  AdSetFields::BILLING_EVENT => AdSetBillingEventValues::IMPRESSIONS,
  AdSetFields::BID_AMOUNT => 2,
  AdSetFields::DAILY_BUDGET => 500,
  AdSetFields::CAMPAIGN_ID => $campaign->id,
  AdSetFields::TARGETING => $targeting,
  AdSetFields::START_TIME => $start_time,
  AdSetFields::END_TIME => $end_time,
));
$adset->create(array(
  AdSet::STATUS_PARAM_NAME => AdSet::STATUS_PAUSED,
));

    In my opinion specifying the longititude and latitude wasn’t a problem.
    I recommend to check error message just directly from developer tool explorer:
    https://developers.facebook.com/tools/explorer

    I prepared request with the same params and response was:

    {
  "error": {
    "message": "Invalid parameter",
    "type": "OAuthException",
    "code": 100,
    "error_subcode": 1885183,
    "is_transient": false,
    "error_user_title": "Ads creative post was created by an app that is in development mode",
    "error_user_msg": "Ads creative post was created by an app that is in development mode. It must be in public to create this ad."
  }
}

    So the reason was clear after it.
