A Shopify Plus client came to us with an issue that they were seeing too many high value baskets go through their payment gateway which were fraudulent. They wanted to put a process in place which made it more secure. They wanted to force customers through the PayPal payment gateway when a basket exceeded $200.
Using some clever logic on the checkout.liquid, we were able to hide the credit card options, when the basket exceeded the limit. We left the only payment option as PayPal and this completely solved the issue!
This provided that extra level of assurance and security for the client meaning if there were ever any issues they could rely on PayPal to help resolve disputes.
