using paypal DoDirectPayment method via HttpWebResponse, Do I need IPN Verification Postback to HTTPS?
<p>I received 
"the request was aborted could not create ssl/tls secure channel. paypal sandbox"</p>

<p>This error occurs on localhost.</p>

<p>But in paypal email they said I do not need to change IPN Verification Postback to HTTPS</p>
