Question

我尝试使用PayPal Reference Transactin。我已经签订了账单，在任何交易完成之前就已经设置了账单协议ID。

我提出了一个简单的交易请求，但得到了：

PPHttpConnection.php第108行中的PPConnectionException：
  访问时获得Http响应代码400   https://api-3t.sandbox.paypal.com/2.0

我的代码（使用merchant-sdk-php包在Laravel 5.3中写入）：

$user=Auth::user();

$currencyCode = 'GBP';
$price=config('constants.offer_submit_price');

$reference_id=$user->userExt()->where('field_name', '=', 'billing_agreement')->firstOrFail()->field_value;
$amount = new BasicAmountType($currencyCode, $price);

$paymentDetails = new PaymentDetailsType();
$paymentDetails->OrderTotal = $amount;

$RTRequestDetails = new DoReferenceTransactionRequestDetailsType();
$RTRequestDetails->PaymentDetails = $paymentDetails;
$RTRequestDetails->ReferenceID = $reference_id;
$RTRequestDetails->PaymentAction ='sale';

$RTRequest = new DoReferenceTransactionRequestType();
$RTRequest->DoReferenceTransactionRequestDetails  = $RTRequestDetails;

$RTReq = new DoReferenceTransactionReq();
$RTReq->DoReferenceTransactionRequest = $RTRequest;

$paypalService = new PayPalAPIInterfaceServiceService($this->config);
try {
    $setRTResponse = $paypalService->DoReferenceTransaction($RTReq);
} catch (Exception $ex) {
    dd($ex);
}

这是由脚本生成的SAOP包络器：

Answer 1

在我朋友的帮助下，我发现了什么是错的。

$RTRequestDetails->PaymentAction ='Sale';

而不是

$RTRequestDetails->PaymentAction ='sale';

PayPal SOAP API需要具有正确区分大小写的所有内容。很遗憾，他们没有发送任何信息有什么不妥。

PayPal参考交易状态代码400作为响应
