Further Reading

Locale. This defines the language of the Feefo emails that you send to a customer including the feedback request email, the merchant response emails and any follow-up emails.

As each line in a sales file can have a single locale defined, one sales file can upload sales data for customers with different locales resulting in the correct language emails being sent to the each customer. If a sale does not have a locale defined or the value entered is not supported or is invalid, then those sales will use the language and country defined by a campaign. 

Supported locale values are:
