When scaling e-commerce logistics or multi-carrier supply chains, operational teams often face a fragmented view of package movements. Standard tracking numbers pass through carrier APIs, provider gateways, and local courier handoffs, producing mismatched status strings.

1. Unified Operational State Normalization

Rather than exposing raw carrier status codes, Track 360 normalizes incoming events into canonical status categories:

Status model

CREATED → PICKED_UP → IN_TRANSIT → OUT_FOR_DELIVERY → DELIVERED

EXCEPTIONS: ADDRESS_HOLD | CUSTOMS_DELAY | DAMAGE_EXCEPTION

2. Guaranteeing Idempotency & HMAC Security

High-volume dispatches deliver webhook payloads asynchronously. To prevent duplicate notification triggers, webhook subscribers verify the X-Webhook-Signature HMAC header against your assigned signing secret.
