Paypal定期付款-立即收费

Question

我正在使用Paypal API，并且我想创建定期付款，第一笔金额应该立即收取。我需要知道它是否成功地为用户解锁了内容。我怎么能做到这一点？

$fields = array(


    'USER' => urlencode('email'),
    'PWD' => urlencode('pass'),
    'SIGNATURE' => urlencode('signature'),
    'METHOD' => urlencode('GetExpressCheckoutDetails'),
    'VERSION' => urlencode('86'),
    'TOKEN' => urlencode($_GET['token'])


);

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://api-3t.sandbox.paypal.com/nvp");
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);  //Post Fields
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);
curl_close ($ch);


// Get PAYERID of 1. query
$payerid = parseNVP($server_output);
$payerid = $payerid['PAYERID'];


$fields2 = array(


    'USER' => urlencode('Email'),
    'PWD' => urlencode('Pass'),
    'SIGNATURE' => urlencode('Signature'),
    'METHOD' => urlencode('CreateRecurringPaymentsProfile'),
    'VERSION' => urlencode('86'),
    'TOKEN' => urlencode($_GET['token']),
    'PAYERID' => urlencode($payerid),
'PROFILESTARTDATE' => urlencode(date('Y-m-d').'T'.date('H:i:s', strtotime('-5 minutes')).'Z'),
'DESC' => urlencode('FitnessMembership'),
'BILLINGPERIOD' => urlencode('Day'),
'BILLINGFREQUENCY' => urlencode('1'),
'AMT' => urlencode($price),
'CURRENCYCODE' => urlencode('USD'),
'COUNTRYCODE' => urlencode('US'),
'MAXFAILEDPAYMENTS' => urlencode('3')


);

Paypal结果：

Answer 1

您可以在为Express Checkout创建定期付款配置文件时收取初始金额。这是来自PayPal开发者网站的文档
在CreateRecurringPaymentsProfile API调用中，您需要使用变量INITAMT

以下是来自PayPal开发者网站的更多信息：

INITAMT

（可选）在配置文件创建。使用初始金额进行注册或设置费用。

注意：请求中包含的所有金额必须具有相同的货币。

字符长度和限制：

价值通常是一个正数，不能超过10000.00美元或货币的每笔交易限额。它不包括货币象征大多数货币需要小数点后两位；十进制分隔符必须是句点（.），可选的千分隔符必须是逗号（，）。有些货币不允许使用小数。请参阅货币代码页面了解详细信息。
