I've spent about an hour trying to figure out what information to use to test credit card transactions in the PayPal Sandbox environment. No matter what I try I get the "Invalid Data This transaction cannot be processed." error. I'm using the Classic API.
I created a personal verified account with a Visa credit card in my developer account but the credit card information generated by the system yield the same error. Here's a screen of the account: https://www.evernote.com/shard/s141/sh/e2a7147c-9cfb-4587-814d-13fdd97d1c29/a1e3d97e505071d6f927a71195f06f2f
After searching I found this post https://www.x.com/developers/paypal/forums/paypal-sandbox/how-test-sandbox-paypal-using-pay-credit-card I then logged into that Sandbox account, went to Profile > Credit/Debit Cards > Add a Card, chose Visa but the credit card number wasn't pre-populate as I had hoped. Here's a screen: https://www.evernote.com/shard/s141/sh/5cfce2b8-da2f-4147-abf5-5d742995b3ca/6d6e1541cbb5809e0e14972d2d81f4bb
I'm really at a loss now. Any help would be really appreciated :)
P.S. I've already tried the cliche test numbers like 4444333322221111 but nothing seems to work.
