customerref is your customer reference number for this customer. Feefo doesn’t use this information but if you would like to import customer comments back into the customer records of your Customer Relationship Management (CRM) software, this is the field to use. The field can also be used to hold additional information that you would like to report against.
The customerref is displayed when logged into the Feefo Hub as part of the Download Sales reports (under Reports > Download Sales). It can also be exported in the CSV file available through Reports > Download Feedback.
