Hello There, I am a VB.Net developer and have a minor challenge in the payment process. To clarify my point, I have an ASP.net application that contains a shopping cart code, The visitor should click on the checkout button to complete the payment process, the challenge I face is how to do this step without visiting Paypal every time he/she adds a new / or to modify items to the shopping cart website. In other words, I want my client to stay at my website to complete the overall process and the final step is going to Paypal to pay for the items at once. so how to update my shopping cart (Items, amount and price most be paid) from .Net Web Application automatically? Is it possible to do it without any third party?
