title: Does PayPal IPN require SSL certificate?
body: <p>I'm using a plugin called PayPal IPN for wordpress. The plugin generates an IPN URL, however, when I try and enter this IPN in to PayPal I get the following error message: </p>
  
  <p>"We're sorry. That URL won't work. Please enter an “https” URL."</p>
  
  <p>This was the plugin generated URL:</p>
  
  <p><a href="http://www.aeroex.co.uk/?AngellEYE_Paypal_Ipn_For_Wordpress&amp;action=ipn_handler" rel="nofollow">http://www.aeroex.co.uk/?AngellEYE_Paypal_Ipn_For_Wordpress&amp;action=ipn_handler</a></p>
  
  <p>I have entered other URLs before and have never seen this message, although the IPNs weren't sent properly. Does this mean that I have to get an SSL certificate for IPNs to be sent through? Thank you. </p>
