Package Tracking

Track by Number

Determine carrier and tracking number. Carrier must be a lowercase Shippo token (e.g., usps, ups, fedex, dhl_express). See shippo/references/carrier-guide.md for tracking number format hints per carrier. If uncertain, ask the user.
Call GetTrack with carrier and tracking_number.
Key response fields: tracking_status (status, status_details, status_date, location), tracking_history, eta.
Each tracking event includes a substatus object with code, text, and action_required (boolean). Include substatus details when presenting tracking history -- these provide more specific information about what happened at each step.
Present: current status, location, ETA, substatus details, and chronological event history (most recent first).

Status Values

See shippo/references/carrier-guide.md for carrier-specific status nuances. Standard values:

Status	Meaning
PRE_TRANSIT	Label created, carrier has not received the package
TRANSIT	Package is in transit
DELIVERED	Delivered
RETURNED	Being returned or returned to sender
FAILURE	Delivery failed
UNKNOWN	No tracking information from carrier

The eta field is provided by most major carriers (USPS, UPS, FedEx, DHL Express) but availability is carrier-dependent, it may be null for regional carriers or for shipments before the carrier has finalized routing. Treat absence as informational, not as an error condition.

Find Trackable Packages

Call ListTransactions. Filter for object_status: SUCCESS. Each successful transaction has tracking_number and carrier info. Then call GetTrack for selected items.

Register a Tracking Webhook

Get the user's HTTPS webhook URL.
Call createWebhook with url and event: track_updated.
Optionally call CreateTrack with carrier and tracking number to register a specific shipment for push updates.
