I made a credit card donation through Stripe, but it was declined and flagged as potential fraud by my credit card company (Amex). I was able to donate successfully after logging into my credit card web site, verifying that I had attempted the transaction, and then resubmitting the donation on the GPG site. So if you get an error message during the donation process, check for messages from your credit card account.
