ℹ️This change was deployed on 14.01.2026.
What's changing?
We've introduced new fields to provide the tracking number and carrier name. You can find them in the new parcel_carrier_tracking_number object for all order item update methods.
"parcel_carrier_tracking_number": {
"carrier": "string",
"tracking_number": "string"
}
This replaces the old parcel_tracking_number and parcel_tracking_carrier fields.
The carrier field expects the carrier slug from the ListAvailableCarriers method. Please let us know if your carrier is missing from this list.
Important: You can now provide either parcel_carrier_tracking_number OR parcel_tracking_url – not both.
The old parcel_tracking_number and parcel_tracking_carrier fields will be deprecated and removed at the beginning of May 2026.
Why this change?
This update ensures better tracking transparency and traceability for your customers.
