We need you help regarding the braintree payment plugin. It was installed on the eshop and the possibility of Credit Card payments is also visible, but after we put in data of a credit card we get the error 0 - nothing here (we are not redirected or anything. Can you please help us?
EDIT: we managed to get it working - it was an issue with a wrong API key. But I have one more question. Where to change the look of the "Payment Failure" if you don't use the correct data from the credit card. I only see this title and nothing else and I would like to add some information why the payment was wrong.
I installed the Braintree payment plugin and I see that the credit card info is added at the last step of the checkout. There is no redirection as with PayPal.
So do I need to enable https and if yes, is this safe enough?
