Question

我一直在搜索PayPal文档两个小时，找不到答案，甚至搜索过谷歌。

点击此处： https://developer.paypal.com/docs/api/#api-operations

我在Maven（REST API）中添加了PayPal的SDK，现在我不确定该怎么做。

我希望使用PayPal API（所有货币）获得帐户余额。

Answer 1

因此，对于在此问题上苦苦挣扎的其他人，文档的“事务搜索”部分下有一个 API 端点，这完全没有意义。

GET /v1/reporting/balances

您将获得一份余额列表，其中包含您在帐户中维护的每种货币。

请参阅此处的文档：

https://developer.paypal.com/docs/api/transaction-search/v1/

Answer 2

GetBalance来自Classsic API，目前尚未包含在REST API中，但您可以直接使用HTTPRequest实现NVP调用，

API端点：

https://api-3t.paypal.com/nvp

POST请求有效负载：

USER=seller_api1.paypal.com
&PWD=56A9R4JPVFPMER2X
&SIGNATURE=AFcWxV21C7fd0v3bYYYRCpSSRl31AociN2kspFBnMbzOGg6NdiC7ZXtg
&VERSION=109.0
&METHOD=GetBalance
&RETURNALLCURRENCIES=1

响应：

L_AMT0=265.17
L_CURRENCYCODE0=USD
TIMESTAMP=2015-08-09T14:21:25Z
CORRELATIONID=802b0b6666022
ACK=Success
VERSION=109.0
BUILD=000000

您也可以使用您喜欢的编程语言获取Classic API SDKs，这次选择“Merchant”SDK。

我的示例PHP代码可帮助您了解流程，

<?php
$version = "124";
$user = "API UserName";
$pwd = "API Password";
$signature = "API Signature";
$API_Endpoint = "https://api-3t.sandbox.paypal.com/nvp";

$resArray = CallGetBalance ( $API_Endpoint, $version, $user, $pwd, $signature );
$ack = strtoupper ( $resArray ["ACK"] );
if ($ack == "SUCCESS") {
    $balance = urldecode ( $resArray ["L_AMT0"] );
    $currency = urldecode ( $resArray ["L_CURRENCYCODE0"] );
    echo "Account Balance: " . $balance . " " . $currency;
}


function CallGetBalance($API_Endpoint, $version, $user, $pwd, $signature) {
    // setting the curl parameters.
    $ch = curl_init ();
    curl_setopt ( $ch, CURLOPT_URL, $API_Endpoint );
    curl_setopt ( $ch, CURLOPT_VERBOSE, 1 );
    curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
    curl_setopt ( $ch, CURLOPT_SSL_VERIFYHOST, FALSE );
    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $ch, CURLOPT_POST, 1 );

    // NVPRequest for submitting to server
    $nvpreq = "METHOD=GetBalance" . "&RETURNALLCURRENCIES=1" . "&VERSION=" . $version . "&PWD=" . $pwd . "&USER=" . $user . "&SIGNATURE=" . $signature;
    curl_setopt ( $ch, CURLOPT_POSTFIELDS, $nvpreq );
    $response = curl_exec ( $ch );

    $nvpResArray = deformatNVP ( $response );

    curl_close ( $ch );

    return $nvpResArray;
}

/*
 * This function will take NVPString and convert it to an Associative Array and it will decode the response. It is usefull to search for a particular key and displaying arrays. @nvpstr is NVPString. @nvpArray is Associative Array.
 */
function deformatNVP($nvpstr) {
    $intial = 0;
    $nvpArray = array ();

    while ( strlen ( $nvpstr ) ) {
        // postion of Key
        $keypos = strpos ( $nvpstr, '=' );
        // position of value
        $valuepos = strpos ( $nvpstr, '&' ) ? strpos ( $nvpstr, '&' ) : strlen ( $nvpstr );

        /* getting the Key and Value values and storing in a Associative Array */
        $keyval = substr ( $nvpstr, $intial, $keypos );
        $valval = substr ( $nvpstr, $keypos + 1, $valuepos - $keypos - 1 );
        // decoding the respose
        $nvpArray [urldecode ( $keyval )] = urldecode ( $valval );
        $nvpstr = substr ( $nvpstr, $valuepos + 1, strlen ( $nvpstr ) );
    }
    return $nvpArray;
}

?>

此答案适用于那些正在寻找适用于节点js或没有任何SDK的REST API的人。

GetBalance（获取特定帐户的余额）

文档链接：https://developer.paypal.com/docs/limited-release/balance-accounts/v2/api/

REST API [GET]：https://api.sandbox.paypal.com/v2/wallet/balance-accounts

请求：

enter code he var excelWorkSheet = (Worksheet)excelWorkBook.Sheets["IT"];
        // excelWorkSheet.dec();
        Range range = excelWorkSheet.UsedRange;
        int rows = range.Rows.Count + 1;
        int cols = range.Columns.Count + 1;
        start = excelWorkSheet.Cells[1, 1];
        end = excelWorkSheet.Cells[rows, cols];

        excelWorkSheet.Activate();

        excelWorkSheet.Cells[6, 5].Value2 = "16/05/2020";
        excelWorkSheet.Cells[7, 5].Value2 = "07/06/2018";
        excelWorkSheet.Cells[8, 5].Value2 = "07/06/2018";
        excelWorkSheet.Cells[9, 5].Value2 = "07/06/2018";
        excelWorkBook.Save();
        excelWorkBook.Close(true, null, null);
        excelApp.Quit();

        Marshal.ReleaseComObject(excelWorkBook);
        Marshal.ReleaseComObject(excelApp);

RES：

curl -v -X GET https://api.sandbox.paypal.com/v2/wallet/balance-accounts \
-H "Content-Type: application/json" \
-H "Authorization: Bearer Access-Token"
