OptionalboxThe ID provided by Amazon that identifies a given box. This ID is comprised of the external shipment ID (which is generated after transportation has been confirmed) and the index of the box.
OptionaltrackingThe tracking ID associated with each box in a non-Amazon partnered Small Parcel Delivery (SPD) shipment.
OptionaltrackingIndicates whether Amazon has validated the tracking number. Because shipment validation is asynchronous, tracking IDs might not be validated immediately, and the status might change after a few hours. If more than 24 hours have passed and the status is not yet 'VALIDATED' or NOT_SUPPORTED, verify the number and update it if necessary. Possible values: VALIDATED, NOT_VALIDATED, NOT_SUPPORTED (Amazon is unable to find tracking information for the provided tracking ID).
