We are using OC V 18.104.22.168 with PayPal Express checkout and (recently added) Square Payments. I liked the fact that Square's form is right on the checkout page and decided to look into the possibility to do the same with PayPal Checkout (not PayPal Pro).
PayPal is suggesting that this can be done (here: https://developer.paypal.com/docs/checkout/#)
PayPal Checkout gives your buyers a simplified and secure checkout experience that keeps them local to your website or mobile app throughout the payment process.
Anyone knows how?
My understanding is that this might have something to do with "Smart Buttons", is this the same as enabling the "PayPal Express Checkout Button" in the Express Checkout extension?
I must stress the importance of using a method that will keep the "seller protection" feature ON.
