php - Paypal 自适应支付(链式)- 链式支付中不允许单边接收方

Question

我一直在尝试使用 Paypal Adaptive Payments API 实现拆分付款。我有一个简单的并行付款可以工作，但是这显示了向买方的两次付款。

基本上我是在卖成员(member)资格。我们本地的协会应该获得75%的资金，25%转交给管理机构。成员(member)应该只能看到 2015 年成员(member)的总金额，因此我开始研究链式支付。从表面上看，这看起来像是一个非常简单的代码更改，但给我带来了与单方面支付相关的问题。

我正在 php 中实现这个。

这里是paypal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。该代码需要大量重构，但只需对当前代码进行少量更改即可完全支持并行支付。

我通过第一个标注得到以下响应 JSON。我认为这与帐户只是沙箱帐户而不是真实帐户有关，但是如果帐户都必须是真实帐户，我该如何在沙箱中测试它呢？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. Unilateral receiver not allowed in chained payment is restricted","parameter":["Account not found. Unilateral receiver not allowed in chained payment"]}]}

Answer 1

我收到了相同的错误消息，并通过确保我在 API 调用中发送付款的 2 个电子邮件地址都是沙盒帐户来修复该问题。它们并不作为真实的电子邮件地址存在，但它们确实需要作为 Paypal 帐户存在。 (之前我将它们发送到沙箱中不存在的 2 个实际的 PayPal 帐户)。

从错误消息“找不到帐户。链式支付中不允许单边接收者”来看，它只是找不到您的帐户，可能是因为它们不是沙盒帐户。
