How can I process a transaction with a duplicate amount?

Upon submitting a transaction with a duplicate amount, Forte returns the following response:


U10:DUPLICATE TRANSACTION - Transaction has the same attributes as another transaction within the time set in the merchant configuration. The default is five minutes but can be disabled or changed upon request.


This issue can be resolved by either of the following methods:

  • Adding an invoice number to the ConsumerOrderID (AGI: ecom_consumerorderid) field
  • Sending different values in a combination of these fields: Merchant ID, Transaction Type, Amount, Consumer Order ID (if present), Credit Card Account Number, or EFT TRN/DDA
