Hello,
I have an e-commerce website on magento 1.9 with Authorize. Many times order is sent to authorize and customer is debited but magento not receive the response and magento retry to sent the order and I have this error message : Gateway error: A duplicate transaction has been submitted.
The result is order is not save and stay as a quote while the customer is debited.
I found this parameters : "x_duplicate_window" default is 120 second, if I change to 0 I wouldn't have this error but I don't know if the customer will be redebited ?
This is my question, if I change x_duplicate_window to 0 and the order is resent to Authorize, the customer will be redebited ?
Thanks
