Our team have developed a website and used Paypal as the payment gateway. They have used the Paypal-rest-SDK library in the node js to integrate Paypal into the website. When I try to make a payment as a guest using debit/credit, sometimes it says that "your credit card has been declined", and sometimes it prompts a message as "we are sorry- things don't appear to be working right now".If anyone can give a solution to this matter, it is highly appreciated
