无法获得付款PayPal快速结帐定期付款工作含税 - can't get payum paypal express checkout recurring payment work with tax

在我的symfony2应用程序中，我正在使用payum PayPal快速结账来执行定期付款。

我在这里按照说明进行操作：https://developer.paypal.com/docs/classic/api/merchant/SetExpressCheckout_API_Operation_NVP/

我想添加项目详细信息，但在输入税务信息时无法使其正常工作。我收到付款错误：

L_SHORTMESSAGE0 =>  Transaction refused because of an invalid argument. See additional error messages for details.
L_LONGMESSAGE0  =>  The totals of the cart item amounts do not match order amounts.

我一直在玩税额，但我无法让它发挥作用。如果我删除所有税务信息，一切都会很好，我会被重定向到金额正确的PayPal。如何配置我的付款以使其正常工作？

请参阅下面发送给PayPal的详细参数：

在我的一个项目中，我使用以下代码在PayPal上发送付款请求（我使用 https://github.com/paypal/merchant-sdk-php）：

    $paymentDetails = new EBLBaseComponents'PaymentDetailsType();
    foreach ($paymentData['items'] as $key => $item) {
        $itemDetails = new EBLBaseComponents'PaymentDetailsItemType();
        $itemDetails->Name = $item['name'];
        $itemDetails->Amount =  new CoreComponentTypes'BasicAmountType($paymentData['currency'], $item['amount']);Order item price
        $itemDetails->Quantity = $item['quantity'];
        $itemDetails->ItemCategory = $item['category'];
        if ($item['tax']) {
            $itemDetails->Tax = new CoreComponentTypes'BasicAmountType($paymentData['currency'], $item['tax']); //Order item tax
        }
        $paymentDetails->PaymentDetailsItem[$key] = $itemDetails;
    }
    $paymentDetails->OrderTotal = new CoreComponentTypes'BasicAmountType($paymentData['currency'],  $paymentData['total']);//Order total
    $paymentDetails->PaymentAction = 'Sale';
    $paymentDetails->ItemTotal = new CoreComponentTypes'BasicAmountType($paymentData['currency'],  $paymentData['subtotal']); //Order subtotal
    $paymentDetails->TaxTotal = new CoreComponentTypes'BasicAmountType($paymentData['currency'], $paymentData['tax']);//Order total tax

    $setECReqDetails = new EBLBaseComponents'SetExpressCheckoutRequestDetailsType();
    $setECReqDetails->PaymentDetails[0] = $paymentDetails;
    $setECReqDetails->CancelURL = $paymentData['cancelUrl'];
    $setECReqDetails->ReturnURL = $paymentData['returnUrl'];
    $setECReqDetails->ReqConfirmShipping = 0;
    $setECReqDetails->NoShipping = 1;
    $setECReqType = new PayPalAPI'SetExpressCheckoutRequestType();
    $setECReqType->SetExpressCheckoutRequestDetails = $setECReqDetails;
    $setECReq = new PayPalAPI'SetExpressCheckoutReq();
    $setECReq->SetExpressCheckoutRequest = $setECReqType;
    try {
        /** @var PayPalAPI'SetExpressCheckoutResponseType $setECResponse */
        $setECResponse = $this->paypal->SetExpressCheckout(
            $setECReq
        );
    } catch ('Exception $ex) {
        $data = array('result' => 'failed');
        $data['errors'] = $this->processConnectionException($ex);
        return $data;
    }

希望对您有所帮助。
