Im having an issues trying to implement paypals Express Checkout Second Redirect option if a user tries to add additional cart items during a paypal payment flow. I am getting the 10001 Error , 'Transaction failed due to internal error'.
Here's the only documentation i can find: Express Checkout Second Redirect
What i have tried so far is to basically repeat the original setExpressCheckout request though adding the paypal TOKEN recieved in the original successful request and then updating the cart items and values.
