我可以成功使用 PayPal NVP api 进行 SetExpressCheckout。但问题是，我无法一次付款给两个商家。所以，通过PayPal，我发现我可以使用并行支付。我需要知道如何使用并行付款。我有 SetExpressCheckout 的请求代码，如下所示，
I can use successfully the PayPal NVP api for SetExpressCheckout. But the problem with this is, I can't pay two merchant on a single payment. So, going through PayPal, I found that I can use the parallel payment. I need to know how can I use the parallel payment. I have request code for the SetExpressCheckout like following,
<form method=post action=https://api-3t.sandbox.paypal.com/nvp>
<input type=hidden name=USER value="[email protected]">
<input type=hidden name=PWD value="xxxxxxxxx">
<input type=hidden name=SIGNATURE value="xxxxxxxxxxxxxxx">
<input type=hidden name=VERSION value=2.3>
<input type=hidden name=PAYMENTACTION value=Order>
<input name=AMT value=10.0>
<input type=hidden name=RETURNURL value=xxxxxx>
<input type=hidden name=CANCELURL value=xxxxxx>
<input type=submit name=METHOD value=SetExpressCheckout>
</form>
I need something like the above where I can request for parallel payment.
