Do I need to have money on my card to link it to my facebook ads account? Do they verify it by taking a small amount like Bing and Paypal? +REP for an answer
I've tried it some times, They only take 1.01$ to verify the card, and then give them back after some days. You should be careful with the limits the vaucher spends, cause sometimes it's limit is not set by default, and the you may end up like me, owing facebook lol.. the best would be, to limit the spending, and remove the credit card after you verify it and start using the vaucher (if it's about the vaucher )
What will happen is an authorization for $1.01 will be placed on your card, the funds will still be in your bank account, but "frozen" to be ready for transfer. Once an authorization is placed and they confirm that, they will release it. No funds are actually debited from your account.
