Google api 使用Adwords API推送离线潜在客户

我正在使用下面的函数将我的离线线索推送到api，一切看起来都很好并返回成功，但当我检查adwords时，它没有显示任何数据表明它已收到。我尝试了很多线索，也等待了大约3-4天

我做错了什么

function UploadOfflineConversionsExample(AdWordsUser $user, $conversionName,$gClId, $conversionTime, $conversionValue) 
{

  // Get the services, which loads the required classes.
 // $conversionTrackerService = $user->GetService('ConversionTrackerService', ADWORDS_VERSION);
  $offlineConversionService = $user->GetService('OfflineConversionFeedService',  ADWORDS_VERSION);

  // Associate offline conversions with the upload conversion we created.
  $feed = new OfflineConversionFeed();
  $feed->conversionName = $conversionName;
  $feed->conversionTime = $conversionTime;
  $feed->conversionValue = $conversionValue;
  $feed->googleClickId = $gClId;

  $offlineConversionOperation = new OfflineConversionFeedOperation();
  $offlineConversionOperation->operator = 'ADD';
  $offlineConversionOperation->operand = $feed;

  $offlineConversionOperations = array($offlineConversionOperation);
  $result = $offlineConversionService->mutate($offlineConversionOperations);

  $feed = $result->value[0];

  return ("Uploaded offline conversion value of ". $feed->conversionValue.
    " for Google Click ID = ". $feed->googleClickId." and Conversion Name " . $feed->conversionName);

}

在adwords报告中，此转换将显示在转换列中。并将日期范围更改为推送的日期，$conversionTime
