Void parcel
The Void Parcel API lets you take out a declared parcel if you do not intend to send it or if it needs to be updated due to changed shipment requirements.
Body
Response
Result of the void request. Object-level problems are reported in the body with the Errors array populated; IsSuccess can still be true for a logged shipper-cancel failure (code C102).
Indicates whether the parcel was voided successfully.
Error entries; empty on success. Documented Void Parcel error codes are C100 and C101 (parcel cannot be voided due to its status), C102 (parcel voided but the shipper's cancel API failed — logged, with IsSuccess still true), C103 (internal unknown failure), and C104 (parcel code not found or already voided).
