Integration of Paypal Smart Button credit card customer payments
I created and saved the Smart Button for my customers to pay by credit card, now I am struggling to paste the code on my Shopify site. I have been trying to set up IP'S calls but failed. I used the instructions but nothing is working. Can someone please help. I am stuck and I cannot make sales, its been weeks now. I try to get support from Paypal but not winning. I need to sell it immediately.
