I have problem with paypal sendbox testing account. I am trying to reproduce failing transaction when there is no enough funds but even when i make PERSONAL test account with 0$ i always get transaction complited and money is always transferd on BUSSINESS account. When i try to pay i get this message:
PayPal will use Discover XXXX-XXXX-XXXX-0295 to fund this transaction if your bank does not have enough funds.
So every time it draws money from that card, but when i try to delete that card from PERSONAL user i am rejected.
Do you know what can cause this problem? :/
