PayPal自適應付款錯誤：API憑據不正確。錯誤代碼：520003

Question

我試圖使用PayPal的PHP SDK及其Adaptive Payments API來創建後端腳本，以自動完成我們網站附屬公司的付款。我已將以下常量設置爲我通過paypal給出的相應值：

define('API_AUTHENTICATION_MODE','3token'); 
define('API_USERNAME', 'xxx'); 
define('API_PASSWORD', 'xxx'); 
define('API_SIGNATURE', 'xxx'); 
define('PAYPAL_REDIRECT_URL', 'https://www.paypal.com/webscr&cmd=_ap-payment&paykey='); 
define('DEVELOPER_PORTAL', 'https://developer.paypal.com'); 
define('DEVICE_ID', 'PayPal_Platform_PHP_SDK'); 
define('APPLICATION_ID', 'xxx'); //(Using correct APP ID given by paypal after registering application 

其中'xxx'等於正確值。

有什麼我失蹤了嗎？每次我試圖發送一個支付與我們的帳戶，我得到錯誤520003.

這是我的職責嘗試發送付款：

編輯： 此外，$ mPayPalEmailAccount被設置爲相同的值作爲API_USERNAME
