Disclaimer!

I am in the process of converting the original coffeescript and callback based project to use Typescript and promises instead. I'll try to keep the below To-Do as up-to-date as possible so feel free to hack away and open up a PR if you wish! I'll be more than happy for the help!

What is this?

Shipping APIs Adapter

trackit is a node module that allows you to retrieve data from shipping carriers like UPS and FedEx in a common format. It interfaces with tracking APIs when available, and falls back to screen scraping. For carriers that expose tracking APIs, user is expected to acquire and provide credentials like license numbers, meter numbers, user IDs and passwords.

Carrier Guessing

Really, why do users have to know that a tracking number was provided by a particular carrier. That step is just totally unnecessary, given that we can guess the carrier from the tracking number in 90% of the cases. trackit provides a convenience function for this.

Try it

There's a Heroku hobby app that allows you to see trackit in action. For example, try this:

http://trackit-api.herokuapp.com/api/carriers/ups/1ZV5E9420444964064

And replace ups with a canonical name for any of the supported carriers, and provide a valid tracking number for that carrier.

Or try this, to detect the carrier(s) associated with a tracking number:

http://trackit-api.herokuapp.com/api/guess/1ZV5E9420444964064

Note: trackit-api Heroku app is not meant for production use, and there are no guarantees included here, regarding it's availability, or up-time. It is only meant as a preview for the trackit node module.

Using the API Adapter

Use it to initialize the shipper clients with your account credentials.

{
  UpsClient,
  FedexClient,
  UspsClient,
  DhlClient,
  LasershipClient,
  OnTracClient,
  UpsMiClient,
  DhlGmClient,
  CanadaPostClient,
  AmazonClient,
  PrestigeClient
} = require 'trackit'

ups = new UpsClient
  licenseNumber: '1C999A999B999999'
  userId: 'trackit-user'
  password: 'shhh-secret'

fedex = new FedexClient
  key: 'xyxyxyxyabababab'
  password: 'asdfawasfdasdfasdf1'
  account: '123456789'
  meter: '99999999'

usps = new UspsClient
  userId: '590XABCR3210'
  clientIp: '10.5.5.1'

lsClient = new LasershipClient()

dhlClient = new DhlClient
  userId: 'SHIPI_79999'
  password: 'trackit'

dhlgmClient = new DhlGmClient()

canadaPostClient: new CanadaPostClient
  username: 'maple-leafs'
  password: 'zamboni'

onTrac = new OnTracClient()

upsmi = new UpsMiClient()

amazonClient = new AmazonClient()

prestige = new PrestigeClient()

Use an initialized client to request tracking data.

ups.requestData {trackingNumber: '1Z1234567890123456'}, (err, result) ->
  console.log "[ERROR] error retrieving tracking data #{err}" if err?
  console.log "[DEBUG] new tracking data received #{JSON.stringify(result)}" if result?

You can use the Amazon client to query status of an item by its order ID and shipment ID (packageIndex defaults to 1 - trackit does not yet support multiple shipments per order).

orderID = '106-9151392-7203433'
orderingShipmentId = 'DmZd0KS8k'
amazonClient.requestData {orderID, orderingShipmentId}, (err, result) ->
  console.log "[ERROR] error retrieving tracking data #{err}" if err?
  console.log "[DEBUG] new tracking data received #{JSON.stringify(result)}" if result?

Note that orderId and shipmentId can be found in the URL embedded in the "Track your package" yellow button. Here's the format of that URL:

https://www.amazon.com/gp/css/shiptrack/view.html
/ref=pe_385040_121528360_TE_SIMP_typ?ie=UTF8
&orderID={orderID}
&orderingShipmentId={orderingShipmentId}
&packageId=1

Example response returned:

{
    "status": 2,
    "activities": [
        {
            "location": "Memphis, TN 38118",

            "datetime": "2014-02-16T17:19:00",
            "details": "Departed FedEx location"
        },
        {
            "location": "East Hanover, NJ 07936",
            "timestamp": "2014-02-15T23:57:00.000Z",
            "datetime": "2014-02-15T18:57:00",
            "details": "Left FedEx origin facility"
        },
        {

            "timestamp": "2014-02-15T15:57:00.000Z",
            "datetime": "2014-02-15T10:57:00",
            "details": "Picked up"
        }
    ],
    "weight": "0.2 LB",
    "service": "FedEx Priority Overnight",
    "eta": "2014-02-17T15:30:00.000Z",
    "destination": "US",
    "request": {
      "trackingNumber": "9400110200881269505160"
    }
}

A Note on timestamp and datetime

There are two types of shipping carriers - one that provide a date and time in their shipping activities that represents the local time at the location indicated. And another that provide a timestamp, which includes a UTC offset. In the first case, since a timezone is not known, trackit just assumes UTC, and returns a timestamp attribute in the activity objects. In the second case, trackit returns a timestamp attribute which has a UTC offset embedded in it, and also a datetime attribute which represents the local time.

Optional parameters for shipper clients

Shipper clients that require account credentials can be provided options as their second argument. And those that don't require any credentials can be provided options as their first argument

upsClient = new UpsClient credentials, [options]
upsmiClient = new UpsMiClient [options]

Valid options:

• raw - response includes the raw response received from the shipping carrier API.
• timeout - how many milliseconds to wait for a shipping carrier API response before returning a timeout error. This option can be overridden by a timeout attribute in the object passed on to the requestData() call.

Using the Carrier Guesser

There's usually only one carrier that matches a tracking number (UPS is the only carrier that uses '1Z' prefix for its tracking numbers), but there are several cases, where there are multiple matches. For example, FedEx uses a service called SmartPost, where it relies on USPS to deliver the package at the last mile. In such cases, FedEx provides tracking through most of the package's journey, and then USPS either takes over, or provides duplicate tracking in the last leg. The tracking number used is the same between the two carriers. Similar situation with UPS Mail Innovations as well. Therefore, the guessCarrier() function returns an array, and we leave it up to the user to decide manually or through other automated means which carrier is the real one or provides more accurate tracking.

{guessCarrier} = require 'trackit'
possibleCarriers = guessCarrier '1Z6V86420323794365'
[ 'ups' ]
possibleCarriers = guessCarrier '9274899992136003821767'
[ 'fedex', 'usps' ]
possibleCarriers = guessCarrier 'EC207920162US'
[ 'usps' ]
