UPS Tracking API for Developers

Use C2W Package Tracking API to retrieve UPS shipment information through RapidAPI. The documented endpoint accepts a tracking number and returns JSON for your application. Webhooks are not supported.

How to request UPS tracking

Subscribe on RapidAPI and keep your credentials on your server.
Send your shipment’s tracking number as trackingNumber to GET /TrackingPackage.
Check the HTTP response before reading tracking fields. Use the API reference for headers and schema.

curl --get 'https://trackingpackage.p.rapidapi.com/TrackingPackage' \
  --data-urlencode 'trackingNumber=YOUR_TRACKING_NUMBER' \
  --header 'X-RapidAPI-Key: YOUR_RAPIDAPI_KEY' \
  --header 'X-RapidAPI-Host: trackingpackage.p.rapidapi.com'

Add an Authorization header only if it was issued for your integration. This example uses a placeholder; it does not query a real shipment.

Illustrative response, not a live shipment

This synthetic subset illustrates documented field names. It is not a recorded UPS response or a guarantee that every shipment supplies these values.

{
  "TrackingNumber": "YOUR_TRACKING_NUMBER",
  "Carrier": "UPS",
  "Delivered": false,
  "Status": "In transit"
}

See authentication and error handling. Keep credentials server-side and treat network failures separately from shipment status.

Plan polling and cost before subscribing

Webhooks are not supported. Your application schedules requests and customer notifications. Results may be cached; a successful call does not imply a new carrier scan.

Example: 25 active shipments checked four times per day use 100 requests, before retries and manual refreshes. The Pro plan includes 150 requests/day at $9.99/month, leaving 50 requests of headroom. This is a workload example, not a recommended polling interval.

The free plan includes 5 requests/day for evaluation. Space requests within the rate limit and stop routine polling when your workflow is complete. Compare plans and request budgets; confirm applicable terms in RapidAPI.

Make status changes useful to your support team.

For a UPS order dashboard, keep the carrier’s event wording alongside your application’s display categories. A normalized badge is useful, but support teams also need the underlying explanation and event time.

Avoid a binary delivered-or-delayed model

An undelivered parcel is not necessarily delayed. Treat the overall status, delivered flag, and event description as separate inputs. Keep an explicit unknown state when data is missing or a response shape is unexpected.

Deduplicate notifications in your application

C2W does not deliver webhooks. If your application polls and sends customer messages, compare the new result with the last stored state before sending another message. Do not treat every successful poll as a new shipment event.

Test the exact services you ship

Use representative UPS shipment numbers from your own workflows during evaluation. Validate available location fields and delivery exceptions, and budget for all active shipments rather than just labels created today.

For a direct integration, consult the UPS developer portal. Direct-carrier setup and entitlements differ from a RapidAPI subscription.

Fields to consider in your application

Integration considerations, not guaranteed field availability
Field	Application handling
`StatusSummary`	Preserve the available summary for support triage.
`TrackingDetails`	Compare events before creating duplicate notifications.
`DestinationState`	Handle absent location data without rejecting the whole response.

Available values depend on the shipment and carrier data. Empty strings, null values, and absent fields should not break your interface. These are schema notes, not a recorded UPS production response.

Before going live

Test delivered, in-transit, unavailable-data, and exception cases for your services. Establish your polling schedule, request headroom, and support process. Use our integration guide and request-budget examples.
