Default application/json Content-Type for tracking push webhooks
Details
We've updated our tracking push subscription methods to set the default content type to application/json for new webhooks and responses, replacing the previous text/plain default. All previously created subscriptions will remain unchanged and continue to use text/plain.

Added shipment registry management methods
Details
Implemented unified registry handling functionality for Client API covering both shipment directions: Ukraine and Europe. The update introduces a single integration approach for registry creation and management across supported regions.
13 MAY 2026 UPDATED
Added custom invoice attachments for business shipments
Details
Now, within the invoice array, you can:
specify whether the invoice is client-provided;
define the invoice type and its attributes;
attach a scanned invoice file.
This allows the system to automatically determine the correct customs codes and synchronize data between the client, Nova Post systems, and customs authorities.
