Hi I am wondering if the user has two credit cards registered in one account. and in case one credit card has failed. Will Paypal detect automatically another credit card and charge? Do we have to do any additional action at the code level? It seems one personal account can create only one credit card to test in the sandbox, is there any way we can test this? if so, do you have any documents in this regard? Awaiting for your kind and soonest reply Best Regards Sonny
