For successful credit transactions submission to the payment gateway using the Upload Transaction File feature, adhere to the following conditions:

• Credits must include the Transaction ID of the original transaction. You can locate Transaction IDs in the transaction details or by downloading the transaction.
• Credits require the full or last four digits of the credit card number. For eCheck.Net credits, provide the bank account number and ABA routing number. Accepted formats are the full number with no spaces, the last four digits only, or the masked number, like XXXX4455.
