Key Concepts

Understanding these concepts will help you use Track123 effectively.

Quota

Quota is the unit of consumption in Track123. Each successful tracking query consumes 1 quota.

Plan
Monthly quota
Overage rate

Starter

50 (Free)

Unavailable after quota exceeded

Pro

300 – 5000

$0.04 per extra query

Advanced

7,000 – 10,000,000

$0.02 per extra query

Enterprise

10,000,000+

Custom

On the Starter plan, tracking stops when the quota is exhausted. Upgrade to Pro or above to enable overage billing and uninterrupted service.

Shipment Status

Track123 normalizes all carrier-specific events into a standardized set of statuses:

Status
Description

Pending

Tracking number created, no carrier scan yet

Info received

Carrier has received shipment information

In transit

Shipment is moving through the carrier network

Out for delivery

Shipment is on the delivery vehicle

Waiting for pickup

Shipment is held at a pickup point

Delivered

Shipment successfully delivered

Exception

Abnormal event (customs hold, damage, address issue, etc.)

Failed attempt

Delivery was attempted but unsuccessful

Expired

No tracking update for an extended period

Carrier Code

Each carrier in Track123 has a unique carrier_code used in API requests. If you don't know the carrier code, you can:

  • Use Carrier Matching in the Shipment page to auto-detect the carrier from a tracking number

  • Query the carrier list via API

API Token

Your API token authenticates all requests to the Track123 API. Pass it as a Bearer token in the Authorization header of every request.

Webhook

A Webhook is an HTTP endpoint on your server that Track123 calls when a shipment status changes. This is the recommended approach for real-time updates — more efficient than polling the API repeatedly.

Carrier Connection

A Carrier Connection lets you link your own carrier account (e.g., your UPS or FedEx account) to Track123. This retrieves tracking data directly from your account rather than through Track123's shared channel, which can improve data freshness and accuracy for high-volume use cases.
