I would think then that they should provide the merchant shopping cart for you to integrate into the website. Seems like that’s on their end, or am I misunderstanding who’s trying to do what?
I am confused also. I have never had someone say “provide shopping cart” . That came from the merchant card provider. The customer doesn’t want the PayPal.
It would be easy if the customer would permit PayPal
Well it sounds to me that they want to use their merchant account which means that the cart has to work with that bank - most banks have very strict guidelines to follow so I wouldn’t waste my time trying to figure out what all those might be and hunting around for a cart. I’d put it back to the client to provide the cart since they’re the ones demanding it work with their merchant account.
