It is important for shippers to preserve agreed dates with the Customer in order to review carrier dates, changes, and build reports. Therefore, we added additional fields like scheduled_at_by_customer and scheduled_ends_at_by_customer which show the dates agreed with the Customer.

Additionally, from now on, carriers cannot change Pickup/Delivery dates set by shippers. Instead, changes to the dates will be stored in the readOnly scheduled_at_by_carrier field.

Please check out order request and response endpoints.
