How to Create an EAN-8 Barcode as a PNG File using Go

Packing & shipping compact products in Europe? You’re going to need a lot of EAN-8 barcodes. Thankfully, generating new barcodes is easy via the Cloudmersive Barcode API endpoint: our EAN-8 Generation API will create a PNG file corresponding to your EAN-8 barcode values.

You can easily take advantage of this API by simply copying & pasting the below code examples (provided here in Go, but also available in several additional programming languages here) into your environment and authenticating the service with a Cloudmersive API key. Registering a free account on our website will provide you with a free-tier API key (which provides a limit of 800 API calls per month & no additional commitments upon reaching that limit), and you can easily scale your operation by choosing from a variety of enterprise level accounts if the need arises.

package main

import (
     "fmt"
     "strings"
     "net/http"
     "io/ioutil"
)

func main() {

     url := "https://api.cloudmersive.com/barcode/generate/ean-8"
     method := "POST"

     payload := strings.NewReader("0=%3C&1=s&2=t&3=r&4=i&5=n&6=g&7=%3E")

     client := &http.Client {
     }
     req, err := http.NewRequest(method, url, payload)

     if err != nil {
          fmt.Println(err)
          return
     }
     req.Header.Add("Content-Type", "application/x-www-form-urlencoded")
     req.Header.Add("Apikey", "YOUR-API-KEY-HERE")

     res, err := client.Do(req)
     if err != nil {
          fmt.Println(err)
          return
     }
     defer res.Body.Close()

     body, err := ioutil.ReadAll(res.Body)
     if err != nil {
          fmt.Println(err)
          return
     }
     fmt.Println(string(body))
}
