title: Does my website require https/ssl for Paypal Express Checkout for recurring payment?
body: <p>I am not sure it is neccessary if I am using PayPal express checkout for recurring payment, do I need https/ssl for my website to connect to PayPal? I am using Ruby on Rails and there is a gem called "paypal-express". It is working well without ssl in sandbox environment. Any suggestion? Thank you.</p>
