Paypal CreateBillingAgreement API Call not working with my api credentials

Question

I am using the master-sdk-php paypal api for making a billing agreement for reference transactions.

I got the token using the api SetExpressCheckout().Below is response :-

PayPal\PayPalAPI\SetExpressCheckoutResponseType Object
(
  [Token] => EC-1EG869789X969882G
  [Timestamp] => 2014-09-08T05:52:43Z
  [Ack] => Success
  [CorrelationID] => 84464deca9458
  [Errors] => 
  [Version] => 104.0
  [Build] => 12658619
)

but it is not working when I am calling the CreateBillingAgreement() api call.

I tested the code with demo api credentials and working fine. But it not working with my api credentials.

It is giving me Internal Error

Below is api call :-

// Include required library files.
require_once($main_path.'paypal_lib/includes/config.php');
require_once($main_path.'paypal_lib/autoload.php');

// Create PayPal object.
$PayPalConfig = array(
                'Sandbox' => $sandbox,
                'APIUsername' => 'bharat.maheshwari_api1.dotsquares.com',
                'APIPassword' => '********',
                'APISignature' => '*******', 
                'PrintHeaders' => $print_headers, 
                'LogResults' => $log_results,
                'LogPath' => $log_path,
                );


$PayPal = new angelleye\PayPal\PayPal($PayPalConfig);

// Pass data into class for processing with PayPal and load the response array into $PayPalResult
$Token = $_REQUEST['token'];
$PayPalResult = $PayPal->CreateBillingAgreement($_REQUEST['token']);

// Write the contents of the response array to the screen for demo purposes.
echo '<pre />';
print_r($PayPalResult);

I have used below api credentials for testing :-

  $PayPalConfig = array(
                'Sandbox' => $sandbox,
                'APIUsername' => 'jb-us-seller_api1.paypal.com',
                'APIPassword' => 'WX4WTU3S8MY44S7F',
                'APISignature' => 'AFcWxV21C7fd0v3bYYYRCpSSRl31A7yDhhsPUU2XhtMoZXsWHFxu-RWy', 
                'PrintHeaders' => $print_headers, 
                'LogResults' => $log_results,
                'LogPath' => $log_path,
                );

And code working fine but not working with my api credentials.I used my details with other adaptive payment api and working fine. It is generating token also with my details.
