    Moneris CA - Error: “Transaction not allowed”


    Moneris Solutions


    Why do some Moneris Customers receive a “Transaction not allowed” error when issuing a refund?


    The error message “Transaction not allowed” typically occurs when a Merchant attempts to issue a refund for a non-existing corresponding sale. To ensure the integrity of your account and protect your business against fraudulent activity, Moneris has turned off this feature by default. If as a customer you wish to have this feature enabled, please feel free to contact the Moneris 24/7 Contact Center at 1-866-319-7450. Please be sure to have your Merchant Account number prior to your call.

    If you have questions or require additional information, please submit a ticket and we will be in touch with you shortly.
