Track Winit parcels through customs clearance and PostNL final-mile delivery.

Winit consolidates cross-border e-commerce parcels under an origin waybill (ID18049202CN) and injects them into PostNL (3SWIN8492018492) via Amsterdam Schiphol / Liège linehaul to PostNL. Querying lastscanned with ?carrier=winit returns origin export and linehaul events, while querying the PostNL tracking number returns domestic final-mile delivery scans.

REST (Synchronous GET)

# 1. Query Winit origin waybill (extracts final-mile barcode in .message):
curl "https://api.lastscanned.com/v1/track/ID18049202CN" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

# 2. Query the extracted PostNL barcode:
curl "https://api.lastscanned.com/v1/track/3SWIN8492018492" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

TypeScript (Automatic Handoff Chaining)

const headers = { Authorization: `Bearer ${process.env.LASTSCANNED_API_KEY}` };
const originRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(number)}`, { headers });
const originPkg = await originRes.json();

// Extract secondary barcode from top-level message ("Handed over to final-mile carrier PostNL (3SWIN8492018492) — Amsterdam Schiphol / Liège linehaul to PostNL")
const handoff = originPkg.message?.match(/^Handed to (.+?) as ([A-Z0-9-]+)$/i);
if (handoff) {
  const [, , lastMileNumber] = handoff;
  const destRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(lastMileNumber)}`, { headers });
