Great! How? When I import a CSV file, on the page that shows the CSV column names on the left of the page and the right of the page provides drop down menus to select the IN invoice field name, the invoice custom field names are not present in the drop down menus (neither as the user defined names or “custom field 1, Custom field 2”).
Can it update invoice custom fields with JSON? Can most the invoice data be imported with CSV and then update the custom fields with JSON? If so, can you give me some example JSON for this? I can’t get the JSON imports to work.
