Paypal 如何获取交易资金来源

我使用api classic和operation TransactionSearch和GetTransactionDetails搜索事务

$transactionSearchRequest = new TransactionSearchRequestType();
$transactionSearchRequest->StartDate = Utils::DateConvert($start_date);
$transactionSearchRequest->EndDate = Utils::DateConvert($start_date + $interval);
$tranSearchReq = new TransactionSearchReq();
$tranSearchReq->TransactionSearchRequest = $transactionSearchRequest;

$paypalService = new PayPalAPIInterfaceServiceService(Configuration::getAcctAndConfig());

$transactionSearchResponse = $paypalService->TransactionSearch($tranSearchReq);
$paypalService = new PayPalAPIInterfaceServiceService(Configuration::getAcctAndConfig());
$transactionSearchResponse = $paypalService->TransactionSearch($tranSearchReq);
print_r($transactionSearchResponse);

答复：

[0] => PaymentTransactionSearchResultType Object (
[Timestamp] => 2015-07-09T01:20:10Z
[Timezone] => GMT
[Type] => Payment
[Payer] => xxx@xxx.com
[PayerDisplayName] => Xxx Inc.
[TransactionID] => xxxxxxxxxxxxxxxxxx
[Status] => Completed
[GrossAmount] => BasicAmountType Object ([currencyID] => USD, [value] => -129.38)
[FeeAmount] => BasicAmountType Object ([currencyID] => USD, [value] => 0)
[NetAmount] => BasicAmountType Object ([currencyID] => USD, [value] => -129.38)
)

但是这个函数（TransactionSearch和GetTransactionDetails（非常大的数组，我不会写响应））没有资金来源，如何获得交易资金来源

另外，很抱歉我的英语不好

您无权访问您收到的交易的资金来源信息

这是发件人的私人信息。

谢谢您的回答，但我有所有的私人数据，这应该是获取此信息的一种方式……您正在查找您发送的交易吗？如果是这样，你可以得到资金来源。如果您正在查找正在接收的事务，则无论是从API还是其他方面，都无法获取该信息。如果是up，则是什么函数？
