C# Barcode API Lookup

Many applications require product data, and given the popularity of C# as a programming language there's no shortage of C#-based apps and tools that need access to a broad array of product information.

Go-UPC is an ideal solution for such applications — especially those that need to scan barcodes — as our database is vast, can provide advanced product information, and includes products in many niches. Provide any UPC or EAN number and (if the product is known) you'll get back a product name, image, description, and more.

Example API Code

Below you'll find some sample C# code that interacts with our API to look up a product by its UPC. In the sample we output the product JSON response.

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

string upc = "5030756007775";
string apiKey = "YOUR_API_KEY_HERE";

string info = GoUPC.API.GetProduct(upc, apiKey).Result;

Console.WriteLine(info);

namespace GoUPC
{
    public static class API
    {
        static readonly HttpClient TheClient = new();

        public static Task<string> GetProduct(string upc, string apiKey)
        {
            string url = $"https://go-upc.com/api/v1/code/" + upc + "?key=" + apiKey;
            return TheClient.GetStringAsync(url);
        }
    }
}
