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 |
