The ‘statement_description_identifier’ in the CreatePayment request is used by Square to construct statement descriptions that are sent to banks. However, it doesn’t replace the business name on the statement. The general format of a statement description that banks include on a customer card or bank statement is as follows: Payment-facilitator-id (For Square-generated descriptors, this value is SQ *), Business name (This is the business name shown in the Seller Dashboard), Delimiter (Square adds this only if you provide the identifier), Identifier (optional) - If a CreatePayment request includes the statement_description_identifier, Square uses the value as the identifier.
So, the business name will always be part of the statement description. The ‘statement_description_identifier’ is an additional piece of information that can help customers understand their statements, but it doesn’t replace the business name.
