In fact, I am developing the Healthcare web application, which should pay my patient the bill. What payment method to use PayPal or how to make a payment in PayPal. I have implemented a basic PayPal payment using the BuyNow button in here . It works fine, but on the PayPal payment page with the “Order Summary” before paying “Thank you for your order” after payment 
, similar to the trade payment, I googled to change them and failed. Is there any other method just for paying bills that meets my requirements. Or how can I change the above payment method to my requirements. Can anybody help me?
