Each payment gateway has varying times for the window time period for when refunds can be issued.
If you receive a message such as 'You are over the time limit to perform a refund on this transaction.' when attempting to issue a refund through your X-CD site, this means that the window to issue the refund through X-CD has passed.
To issue the user a refund, you will need to login to your merchant account and issue a direct refund from your payment gateway account, then return to X-CD and record a system credit for the refunded amount.
