Why is the Paypal Sandbox not processing payments?

Question

I\'m making an e-commerce site and the paypal integration is seemingly working. I have a shopping cart, that totals up all the items inside, adds the shipping price and then

Answer 1

To anyone else who stumbles on this question later. I did solve it. Once the user returns to your site after confirming the payment on paypal you still have to send a DoExpressCheckoutPayment request to the paypal servers to get the payment to process.

You would supply the PayerID and TOKEN to DoExpressCheckoutPayment to process it. The PayerID is appended in the URL of your RETURNURL, or can be retrieved by calling GetExpressCheckoutDetails with the TOKEN.

Answer 2

I faced same issue when I integrated pay pal and it seems that there has been some modification in their system.

if you go to your buyer account you could see your payments in pending state and to be approved in a couple of days, same behavior for merchant account.
