We would like to connect our shopping cart with PayPal Express Checkout
The PayPal express checkout systems allows customer to buy products on our shopping cart and checkout direcly using PayPal express? without having to create an account on our merchants site
After the payment, the paypal api should update our database (orders and customers tables) and write in them customer details and orderdetails.
The other par of this developpement is we need to retain customers paypal credentials (we want to keep on file their credentials) so that if they are logged in our shopping cart, thy can click on checkout button and make payments without having to log into paypal and confirm the payment from paypal page
