 * I have not purchased an SSL certificate for my site yet, but in the settings 
   for Seamless Donations, the PayPal settings say:
 * “Congratulations! Your site appears compatible with PayPal’s requirements.
    cURL:
   7.35.0, SSL: OpenSSL/1.0.1f, HTTPS: responds”
 * Does this mean I can just use the “[https://&#8221](https://&#8221); IPN URL 
   without the need for me to purchase a separate SSL for the site?
 * Thanks

 * The answer is a full and complete “maybe.” During my testing, I discovered that
   some hosts had enabled some level of SSL on their sites, without a certificate.
   When I cut and pasted the IPN into a browser, I got back that “you might not 
   be entering a safe space” message, which indicated that they had https set up
   and working, but not an actual certificate.
 * That sort of situation will sometimes successfully round-trip to PayPal, but 
   I’m reasonably convinced it will break at an inopportune time. So, if it works,
   consider it worthy for basic testing, but when you want to do this for real, 
   you probably should use a Let’s Encrypt free certificate or buy one. I bought
   a $9 for my test environment and it’s a good quality Comodo certificate.
 * Here is some helpful reading on SSL. To understand why we’re dealing with this,
