Question

这是我第一次发帖：我希望将PayPal API集成到我的网站中，我可以成功完成付款，但不能退款部分。我在lib文件夹中看到退款api;但是，我不确定要使用哪个ID，我没有看到很多关于退款的例子。

这就是我现在所拥有的：

$refund = new Refund();
$refund->setId($payment_id);
$refund->setAmount(1000);
$refund->get($payment_id, $this->apiContext);


try {
    //$refund = Refund::get();
} catch (Exception $ex) {
// NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY

ResultPrinter::printError("Get Payment", "Payment", null, null, $ex);
            exit(1);
}

// NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY

return json_decode($payment, 128);

付款明细是：

Answer 1

执行付款后，您将获得sale =＆gt; ID。这是你用来退款的身份。

它还会在Transactions =＆gt; related_resources =＆gt;链接中包含一个完整的URI，其中包含'rel'值为'refund'的链接。

Answer 2

每笔付款都会生成一个sale_id作为例子4CFG677234DFG234F。该ID将用于退款。

不要让自己与付款ID和sale_id混淆。
