**NOTES**:

- *Can only be modified via the [`CreateOrder` call](/apis/shipstation-v1/docs/orders/create-update-order). Using the [`CreateLabelForOrder`](/apis/shipstation-v1/openapi/shipments/create_shipment_label) will default these fields to the values set prior to the call.
- [`CreateLabelForOrder`](/apis/shipstation-v1/openapi/shipments/create_shipment_label) will not affect *billTo* values. Calls will default *billTo* fields to the values set in the order.
- **Setting `billToParty` attribute to "my_other_account" is used when wanting to charge a second connected account for the same carrier.
