title: Paypal dynamic subscription button ipn
body: <p>I am using this code I found:</p>
  
  <pre><code>&lt;form name="_xclick" action="https://www.sandbox.paypal.com/cgi-bin/webscr method="post"&gt;
  &lt;input type="hidden" name="cmd" value="_xclick-subscriptions"&gt;
  &lt;input type="hidden" name="business" value="me@example.com"&gt;
  &lt;input type="hidden" name="currency_code" value="USD"&gt;
  &lt;input type="hidden" name="no_shipping" value="1"&gt;
  &lt;input type="image" src="http://www.paypal.com/en_US/i/btn/btn_subscribe_LG.gif" border="0" name="submit" alt="Make payments with PayPal - it's fast, free and secure!"&gt;
  &lt;input type="hidden" name="a3" value="5.00"&gt;
  &lt;input type="hidden" name="p3" value="1"&gt;
  &lt;input type="hidden" name="t3" value="M"&gt;
  &lt;input type="hidden" name="src" value="1"&gt;
  &lt;input type="hidden" name="sra" value="1"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>When you generate a button from paypal site, it gives you the option to select the link where to send the ipn. My question is, how do I get the ipn confirmation using the code above or how do I set the link for it?</p>
