如何在 PayPal 沙箱中进行 PayPal DoCapture API 调用？

Question

我已使用以下表格发送 PayPal DoCapture API 调用，这是进行 API 调用的正确方法吗？我使用的是 PayPal 标准账户

<form id="paymentForm" action="https://svcs.sandbox.paypal.com/AdaptiveAccounts/DoCapture" method="post" name="paypal">         
    <input id="METHOD" name="METHOD" type="hidden" value="DoCapture" />
    <input id="AUTHORIZATIONID" name="AUTHORIZATIONID" type="hidden" value="7M4218491W8104419" />
    <input id="AMT" name="AMT" type="hidden" value="10" />
    <input id="CURRENCYCODE"  name="CURRENCYCODE" type="hidden" value="EUR" />
    <input id="COMPLETETYPE" name="COMPLETETYPE" type="hidden" value="NotComplete" />
    <input id="STOREID" name="STOREID" type="hidden" value="938738701158035" />         
    <input type="submit" value="Proceed with Payment" id="submit2" name="SUBMIT2"/>
</form>

它显示内部错误？同时我不关心 STOREID 参数.. 这是什么？

任何人都可以通过示例帮助我实现 DoCapture API 调用。

Answer 1

变量STOREID 是提供退款的商家商店的标识符。销售点交易需要此字段。

字符长度和限制：50 个单字节字符

此字段从 82.0 版开始可用。

对于您的表单，您使用的 URL 不正确。 DoCapture API 请求不会发送到 https://svcs.sandbox.paypal.com/AdaptiveAccounts/DoCapture。 DoCapture 需要发送到商家 API 端点之一。那么这取决于您使用的是 NVP 还是 SOAP，以及 API 签名还是证书。您可以找到不同端点here 的列表。确保您指向正确的端点。

我已经在 CodeIgniter 的 PayPal 沙箱代码中创建了 PayPal DoCapture API 调用。

public function get_execute_docapture($product_id = '', $paypal = '') {

    $serverName = $_SERVER['SERVER_NAME'];
    $serverPort = $_SERVER['SERVER_PORT'];
    $url = dirname('http://' . $serverName . ':' . $serverPort . $_SERVER['REQUEST_URI']);
    $currencyCodeType = "USD";
    $paymentType = 'Authorization';
    $personName = "Balasaheb Bhise" . " " . "Balasaheb Bhise";
    $SHIPTOSTREET = $_REQUEST['SHIPTOSTREET'];
    $SHIPTOCITY = $_REQUEST['SHIPTOCITY'];
    $SHIPTOSTATE = $_REQUEST['SHIPTOSTATE'];
    $SHIPTOCOUNTRYCODE = $_REQUEST['SHIPTOCOUNTRYCODE'];
    $SHIPTOZIP = $_REQUEST['SHIPTOZIP'];
    $card_name = "";
    $L_NAME0 = 'demo';
    $L_AMT0 = 10;
    $L_QTY0 = 1;
    $L_NAME1 = '';
    $L_AMT1 = 0;
    $L_QTY1 = 0;
    $returnURL = (base_url() . 'product/get_execute_docapture/' . $product_id . 'paypal/');
    $cancelURL = (base_url() . 'product/get_execute_docapture/' . $product_id);
    $itemamt = 0.00;
    $itemamt = $L_QTY0 * $L_AMT0;
    $amt = $itemamt;
    $maxamt = $itemamt;
    $nvpstr = "";

    //  Send transaction id hear
    $AuthorizationId = $transaction_id;
    /*
     * Setting up the Shipping address details
     */
    $shiptoAddress = "&SHIPTONAME=$personName&SHIPTOSTREET=$SHIPTOSTREET&SHIPTOCITY=$SHIPTOCITY&SHIPTOSTATE=$SHIPTOSTATE&SHIPTOCOUNTRYCODE=$SHIPTOCOUNTRYCODE&SHIPTOZIP=$SHIPTOZIP";

    $nvpstr = "&ADDRESSOVERRIDE=1$shiptoAddress&L_NAME0=" . $L_NAME0 . "&L_NAME1=" . $L_NAME1 . "&L_AMT0=" . $L_AMT0 . "&L_QTY0=" . $L_QTY0 . "&MAXAMT=" . (string) $maxamt . "&AMT=" . (string) $amt .

    $nvpstr = $nvpHeader . $nvpstr;

    $resArray = hash_call("DoCapture", $nvpstr);

    echo "<pre>";
    print_r($resArray);
    echo "</pre>";
}
