Korrio offers integrated refund functionality that allows an Organization admin to initiate a refund in Korrio for processing in your respective payment vendor. Recently, authorize.net made a backend change that in some cases prevented our integrated refunds from processing.
If you couldn’t issue a refund from Korrio, you may be experiencing this configuration related issue. Try this:
1. Go to authorize.net
2. Go to account, then payment form, then form fields
3. Remove all the check boxes
4. Save changes
