Hello folks, I’m trying to import customer data via a csv file. I also need to import the customer language and TVA number. Herefore I created extra columns named ‘customer_language’ and ‘VAT Number’. I found the correct columns headers in the Shopify Helpdesk files. Unfortunately the import fails and the error message stipulates that the headers are not accepted. I also created extra Meta Fields to receive the data but this didn’t bring a solution neither. thanks for your help!
