Paypal自适应支付(链式）-在链式支付中不允许单边接收者

我一直在尝试使用Paypal自适应支付API实现拆分支付。我有一个简单的平行付款，但这显示了对买家的两次分期付款。

基本上我是在出售会员资格。我们的地方协会应该获得75%的资金，25%的资金将转交给管理机构。会员应该只看到2015年的会员总数，所以我开始研究连锁支付。从表面上看，这看起来像是一个非常简单的代码更改，但却给我带来了与单方面付款有关的问题。

我正在php中实现这一点。

所以这里是贝宝发送方法

function PaypalSend($payment_details, $api_function){
    // initial endpoint that starts the transaction
    $paypalInitialEndpoint = 'https://svcs.sandbox.paypal.com/AdaptivePayments/';
    // set http headers
    $headers = array(
        'Connection: Close',
        'X-PAYPAL-SECURITY-USERID: testseller_api1.nipf.com',
        'X-PAYPAL-SECURITY-PASSWORD: 1381912839',
        'X-PAYPAL-SECURITY-SIGNATURE: AzykGe5AzfK.mJFMRzBwIcTap-LcAsmsP4AhYzk1Y-07mh-xPLc-goK3',
        'X-PAYPAL-APPLICATION-ID: APP-80W284485P519543T',
        'X-PAYPAL-REQUEST-DATA-FORMAT: JSON',
        'X-PAYPAL-RESPONSE-DATA-FORMAT: JSON'
    );
    // setup curl request and http headers
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $paypalInitialEndpoint . $api_function);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($payment_details));
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    if(!($res = curl_exec($ch)) ) 
    {   
        error_log(curl_error($ch));    
        curl_close($ch);    
        exit;
    }
    curl_close($ch);
    return json_decode($res, TRUE);     
}

这是我的链式付款方式。这段代码需要大量的重构，但在并行支付中功能完全，只对当前代码进行了微小的更改。

function sendChainedPayment(){
    $purchase_details_array = array(
        "actionType" => "PAY",
        "currencyCode" => "GBP",
        "feesPayer" => "PRIMARYRECEIVER",
        "memo" => "blah blah blah",
        "receiverList" => array(
            "receiver" => array(
                array(
                    "amount" => "30.00", 
                    "email" => "testseller@nipf.com",
                    "primary" => "true"
                ),
                array(
                    "amount" => "10.00", 
                    "email" => "testseller@gbpf.com",
                    "primary" => "false"
                )           
            )
        ),
        "returnUrl" => "http://localhost/membershipSuccess.php",
        "cancelUrl" => "http://localhost/membershipCancel.php",
        "requestEnvelope" => array(
            "errorLanguage" => "en_UK",
            "detailLevel" => "ReturnAll"
        )
    );
    $response = PaypalSend($purchase_details_array, "Pay");
    //echo json_encode($response) . "<br /><br />";
    $payKey = $response['payKey'];
    $payment_details = array(
        "requestEnvelope" => array(
            "errorLanguage" => "en_UK",
            "detailLevel" => "ReturnAll"
        ),
        "payKey" => $payKey,
        "receiverOptions" => array(
            array(
                "receiver" => array("email" => "testseller@nipf.com"),
                "invoiceData" => array(
                    "item" => array(
                        array(
                            "name" => "Membership 2015",
                            "price" => "30.00",
                            "identifier" => "Membership 2015: joe bloggs"
                        )
                    )                                               
                )
            ),
            array(
                "receiver" => array("email" => "testseller@gbpf.com"),
                "invoiceData" => array(
                    "item" => array(
                        array(
                            "name" => "Membership 2015 (Fee)",
                            "price" => "10.00",
                            "identifier" => "Membership 2015 (Fee): joe bloggs"
                        )
                    )                                               
                )
            )
        )
    );
    $response = PaypalSend($payment_details, "SetPaymentOptions");
    //echo json_encode($response) . "<br /><br />";
    $paypalCustomerUrl = 'https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-payment&paykey=' . $payKey;
    echo $paypalCustomerUrl;
    //header('Location: ' . $paypalCustomerUrl);        
}

我得到了以下带有第一个callout的响应JSON。我认为这与账户只是沙盒账户而不是真实账户有关，但如果账户都必须是真实账户，我该如何在沙盒中测试这一点？在这种情况下，用作API帐户的帐户是主要接收者。

{"responseEnvelope":{"timestamp":"2015-02-04T14:37:26.598-08:00","ack":"Failure","correlationId":"749bd1d709e76","build":"15089777"},"error":[{"errorId":"520009","domain":"PLATFORM","subdomain":"Application","severity":"Error","category":"Application","message":"Account Account not found.
