Even though both my seller account and buyer account are linked to Paypal's sandbox, the Paypal option in checkout does not work. A pop up window appears saying "There's been a problem. Please try again." How do you pay with Paypal in the sandbox?
Hi @sanjiv_developersupport, Thank you for your reply. The CC checkout method works, but I have I am having a problem with Combined Invoices. I have created multiple line order orders by purchasing two of the same item, but when I processed to checkout there is only one item in checkout. How do you purchase multiple items in the sandbox? I appreciate your time and any insight you can provide.
