If you cannot place (accomplish) an order and you get a message like "Authorization failed", then one of the following issues might be the case:
Reason for the message: The information passes validation on our end and an actual authorization request is sent but the bank is declining the authorization. The most common cause for this error is that the seller is located outside of the country that the bank is located in so it is showing up as an international transaction.
How to resolve the issue: Contact the bank and let them know that you want the transaction to go through (they will be able to see the authorization attempts) and then replace the order. If they still receive problems then their purchase session is probably locked because of previous declines. They must wait 30 minutes, use a different browser or clear their cookies and restart their browser so that a new purchase session is used when they replace the order.
Authorization Failed: Authentication Failed
Reason for the message: The authorization requires Verified by Visa or MasterCard secure code authentication. In most cases the bank cannot even see the authorization attempt unless it passes this authentication.
How to resolve the issue: Troubleshooting should be done by first insuring that they are being sent to a page on their bank's server (if not it is most likely a popup blocker issue) and then insuring that they signup for the service (VBV or MCSC). If a page is not loading and they are not using a popup blocker then the issue is most likely a session locking issue and they should either wait 30 minutes or clear their cookies and restart their browser so that a new purchase session is used when they replace the order.
Authorization Failed: Authorization Failed
Reason for the message: We intentionally lock the purchase session after a specific number of unsuccessful attempts. Any attempts after this will get this error message and we won't actually attempt anything until a new purchase session is started.
How to resolve the issue: Either wait 30 minutes so a new purchase session is started or clear browser cookies, restart the browser and then replace a new order. If you still get this error message then you are still on the same order session.
