merchant identifier is used in both sales files and product catalogues to define the merchant’s unique Feefo identifier which is usually in the form merchantname-com. The value of the merchant identifier can be found in the Feefo Hub under 'Settings > Business Details > Feefo Account Details > Merchant Identifier'. The value used in either file must be identical to that published in the Hub. Take a look at Find Your Merchant Identifier for further guidance.
Usage is as follows:
|File type||TXT/CSV file field name||XML field name (case sensitive)||Required/Optional||Default value|
|Sales file||merchant identifier||merchant_identifier||Required||None|
|Product catalogue||merchant identifier||N/A||Required||None|
