Because of different rules and regulations in different countries, we may need certain additional information along with your request depending on the country related to the request. These required fields can be fetched with this endpoint, together with an example value describing the format in which it should be supplied.
If the response contains only an empty array, it means the country that the request is bound to does not require any required fields to be added.
