如何使用 php 为广告创意制作 Facebook 营销 API？

Question

I am trying to create an ad creative but getting an invalid parameter error. The exception even does not specify which parameter is wrong.

try {
     $link_data = new AdCreativeLinkData();
     $link_data->setData(array(
           AdCreativeLinkDataFields::MESSAGE => 'try it out',
           AdCreativeLinkDataFields::LINK => 'http://www.google.com',
           AdCreativeLinkDataFields::IMAGE_HASH => '704e55dbf724243acfb8457a4f68a92a',
         ));
    
     $object_story_spec = new AdCreativeObjectStorySpec();
     $object_story_spec->setData(array(
           AdCreativeObjectStorySpecFields::LINK_DATA => $link_data,
     ));
    
     $creative = new AdCreative(null, 'act_576834712392068');
    
     $creative->setData(array(
           AdCreativeFields::NAME => 'Sample Creative Suite CRM',
           AdCreativeFields::OBJECT_STORY_SPEC => $object_story_spec,
     ));
     $creative->create();
} 
catch (Exception $e) {
  echo 'Caught exception: ',  $e, "\n";
}

Caught exception: exception 'FacebookAds\Http\Exception\AuthorizationException' with message 'Invalid parameter'

Answer 1

It seems you have not added the Page where the creative has to be posted. I think adding AdCreativeObjectStorySpecFields::PAGE_ID => 'your published page id here' in object_story_spec array will resolve your problem.

Don't forget to set your app's status to active from development. It was the reason of the same failure. You can check your error in more detail with

catch (Exception $e) {
    var_dump($e)
}
