|---|---|---|---|
| SortField | string | The field to sort by. Important: When using a `DateTimeFilter`, `sort_field` must match the timestamp field that the DateTimeFilter uses to filter. For example, If you set your `sort_field` to `CLOSED_AT` and you use a DateTimeFilter, your DateTimeFilter must filter for orders by their `CLOSED_AT` date. If this field does not match the timestamp field in `DateTimeFilter`, SearchOrders will return an error. Default: `CREATED_AT`. See SearchOrdersSortField for possible values | [default to null] |
| SortOrder | string | The chronological order in which results are returned. Defaults to `DESC`. See SortOrder for possible values | [optional] [default to null] |
