Currently, we do not have the capability to edit a GoCorp Voucher Code. However, we are allowing the admin to disable a voucher when the voucher is in “Active” status. Please create a new program to make amendments and ensure that you disable the previous code so no usage will be charged from the previous code. 
 

To disable the voucher program, just go to your voucher code page and find your voucher program and switch the button to disabled in the voucher list.
