Ошибка аутентификации. Либо предоставленные учетные данные недействительны, либо учетная запись неактивна

Я пытаюсь пройти аутентификацию на Bing Ads Api, но получаю следующее сообщение:

Ошибка аутентификации. Либо предоставленные учетные данные недействительны, либо учетная запись неактивна

Это мой код:

$UserName = "[email protected]";
$Password = "xxx";
$DeveloperToken = "xxx";
$CustomerId = xxx;
$AccountId = xxx;

$wsdl = "https://campaign.api.bingads.microsoft.com/Api/Advertiser/CampaignManagement/V10/CampaignManagementService.svc?singleWsdl";
try
{
$proxy = ClientProxy::ConstructWithAccountAndCustomerId($wsdl, $UserName, $Password, $DeveloperToken, $AccountId, $CustomerId, null);

// Specify one or more campaigns.

$campaigns = array();

$campaign = new Campaign();
$campaign->Name = "Winter Clothing " . $_SERVER['REQUEST_TIME'];
$campaign->Description = "Winter clothing line.";
$campaign->BudgetType = BudgetLimitType::MonthlyBudgetSpendUntilDepleted;
$campaign->MonthlyBudget = 1000.00;
$campaign->TimeZone = "PacificTimeUSCanadaTijuana";

$campaign->TrackingUrlTemplate =

$campaigns[] = $campaign;
// Add the campaign, ad group, keywords, and ads

$campaignIds = AddCampaigns($proxy, $AccountId, $campaigns);
PrintCampaignIdentifiers($campaignIds);

}
catch (SoapFault $e)

// If the AdApiError array is not null, the following are examples of error codes that may be found.
foreach ($errors as $error)
