title: Need example code for PayPal NVP api request code for parallel payment
body: <p>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, 
  <code>&lt;form method=post action=https://api-3t.sandbox.paypal.com/nvp&gt;
  &lt;input type=hidden name=USER value="xxxxxxxxxxxxx@xxxxx.com"&gt;
  &lt;input type=hidden name=PWD value="xxxxxxxxx"&gt;
  &lt;input type=hidden name=SIGNATURE value="xxxxxxxxxxxxxxx"&gt;
  &lt;input type=hidden name=VERSION value=2.3&gt;
  &lt;input type=hidden name=PAYMENTACTION value=Order&gt;
  &lt;input name=AMT value=10.0&gt;
  &lt;input type=hidden name=RETURNURL value=xxxxxx&gt;
  &lt;input type=hidden name=CANCELURL value=xxxxxx&gt;
  &lt;input type=submit name=METHOD value=SetExpressCheckout&gt;
  &lt;/form&gt;</code> 
  I need something like the above where I can request for parallel payment.</p>
