Cancel Shipments

If you no longer need a shipment record for any reason, you can cancel it. If the shipment has any labels associated with it, you’ll need to void the label first. For example, a common use case would be if a batch label creation job is going to run at a set time and only queries pending shipments. Canceling the shipment would remove it from this process.

Requirements

The shipment_id
Any labels that have been created for that shipment first need to be voided.
