You may be wondering if it is possible to edit or rename your custom fields in Marketo.
Solution
Yes, editing or renaming your custom fields in Marketo is possible.
You can do so by navigating to "Admin" > "Field Management" > Click on the field on the right-hand side field list > click on the name of the field in the centre canvas (UI) then edit.
Your fields would need to be unused by any asset in order for you to edit/rename them.
