Q: Why am I getting a "23: duplicate" error on a repeat transaction?

A: The system is returning this error as a security measure because either the same payment or refund request was sent too many times in quick succession or the same credit card number was used for the same transaction amount twice in one day. This can be remedied in one of the following ways:

  • Use a different payment method when available
  • Temporarily change the value of the item by at least $.01
  • Attempt the second transaction again on the next business day
