Php 地址验证API—；没有进行此API调用的权限

我在沙盒模式下调用了PayPal的AddressVerify API，但返回时出错

[L_ERRORCODE0] => 10002
[L_SHORTMESSAGE0] => Authentication/Authorization Failed
[L_LONGMESSAGE0] => You do not have permissions to make this API call
[L_SEVERITYCODE0] => Error

我的地址验证代码是

function verify_address($PayPalConfig, $email, $street, $zipcode) {

    $PayPal = new PayPal($PayPalConfig);

    $AVFields = array(
        'EMAIL' => $email,
        'STREET' => $street,
        'ZIP' => $zipcode,
    );

    $PayPalRequestData = array(
        'AVFields' => $AVFields,            
    );

    $PayPalResult = $PayPal->AddressVerify($PayPalRequestData);
    return $PayPalResult;

}

我想知道是否有任何设置可以启用此API调用或任何其他将成功调用此API的方法？

地址验证通常不使用sandbox启用。因此，您需要打开一个支持请求或拨打电话来启用该功能
