Authorize.net users, has a traveler reported receiving an alert that their credit card was declined, but they were charged anyway?
THIS HAPPENS WHEN:
This is usually related to an Address Verification Service (AVS) mismatch issue, which means that the address your traveler gives for their billing information does not match the billing information linked to their credit card. The charge will then show up on their credit card statement, as a hold.
Your traveler might see the declined error (see image below) and complete the transaction again right away, but then they will feel like they have paid twice until the hold is released.
See below for Authorize.net's description of why this may be happening & what you can do to expedite the return of your traveler's funds.
