'How to make Facebook Marketing API for Ad Creative using php?

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'

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)
}
