Tracking — Parcels

The Tracking Parcels endpoint lets you fetch the current status, carrier events, and line items of any parcel owned by your shop, using the tracking number you already have (e.g. from the carrier label or the Baback dashboard).

This endpoint uses the same base URL and Bearer token as the Shipping Labels API: https://api.baback.co.

Authentication

Every request uses a Bearer token — the same token you use for the Returns and Shipping Labels APIs.

Authorization: Bearer

The token automatically identifies your shop. A missing or invalid token returns 403 Forbidden.

Rate limiting

Limit	Window
100 requests	60 seconds

Going over the limit returns 429 Too Many Requests.

GET/public/v1/tracking/parcels/:trackingNumber

Get a parcel by tracking number

Returns parcel info — carrier status, events, destination address, and line items — for a given tracking number, strictly scoped to the authenticated shop. A tracking number that belongs to another shop returns 404 (and does not reveal its existence).

The :trackingNumber parameter is matched against two fields:

trackingId — the primary tracking number of the parcel
trackingNumbers[] — the array of tracking numbers for multi-package shipments

If multiple parcels of the same shop match, the most recently created one is returned (orderBy: createdAt desc).
