ForceSendFields is a list of field names (e.g. "BuyLink") to unconditionally include in API requests. By default, fields with empty values are omitted from API requests. However, any non-pointer, non-interface field appearing in ForceSendFields will be sent to the server regardless of whether the field is empty or not. This may be used to include empty fields in Patch requests.
