A simple and powerful multi-carrier shipment tracking API that supports USPS, UPS, FedEx, DHL, LaserShip/OnTrac, Roadie, GoFor, and UniUni using a single REST endpoint.

This repository demonstrates how to use the API in C# (.NET).

🚀 Why This API?

Shipping integrations are usually complex because each carrier has:

Different APIs Different authentication methods Different response formats

This API solves that by providing:

✔ One API for all carriers ✔ Automatic carrier detection ✔ Unified JSON response ✔ Full tracking history ✔ Simple REST integration ✔ Free tier available

🔗 Get Started (Important)

Before using the API:

👉 Go to RapidAPI and subscribe to the Basic Plan (Free)

https://rapidapi.com/c2wtechnology/api/trackingpackage

Then open the Playground to test requests instantly in the browser.

🔑 API Endpoint GET https://trackingpackage.p.rapidapi.com/TrackingPackage?trackingNumber={TRACKING_NUMBER}

📌 C# Example – Track a Package

This example shows how to call the Multi-Carrier Tracking API using C# HttpClient.

using System;
using System.Net.Http;
using System.Threading.Tasks;


using System;
using System.Net.Http;
using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        var trackingNumber = "9200190312809701574398";

        using var client = new HttpClient();

        // RapidAPI headers
        client.DefaultRequestHeaders.Add("X-RapidAPI-Key", "YOUR_RAPIDAPI_KEY");
        client.DefaultRequestHeaders.Add("X-RapidAPI-Host", "trackingpackage.p.rapidapi.com");

        // API endpoint
        var url = $"https://trackingpackage.p.rapidapi.com/TrackingPackage?trackingNumber={trackingNumber}";

        // Send request
        var response = await client.GetAsync(url);
        response.EnsureSuccessStatusCode();

        var content = await response.Content.ReadAsStringAsync();

        Console.WriteLine("Tracking API Response:");
        Console.WriteLine(content);
    }
}
