Transaction Verification

Before a customer transaction is complete, merchants can use the transaction verification API to authenticate the legitimacy of their customer's transaction. It is, therefore, a standard practice to verify the status of a transaction after it has been completed.

Implementation

Let's walk you through the process. Here is an implementation

curl --location --request GET 'https://www.netappspay.com/pg/api/v1/transaction/status/NT-28e275b3e5a998' \
  --header 'Authorization: Bearer 4c219509e1ad4629823a91255bd7b477'

var request = require('request');
  var options = {
    'method': 'GET',
    'url': 'https://www.netappspay.com/pg/api/v1/transaction/status/NT-28e275b3e5a998',
    'headers': {
      'Authorization': 'Bearer 4c219509e1ad4629823a91255bd7b477'
    }
  };
  request(options, function (error, response) {
    if (error) throw new Error(error);
    console.log(response.body);
  });

Unirest.setTimeouts(0, 0);
  HttpResponse<String> response = Unirest.get("https://www.netappspay.com/pg/api/v1/transaction/status/NT-28e275b3e5a998")
    .header("Authorization", "Bearer 4c219509e1ad4629823a91255bd7b477")
    .asString();

package main

  import (
    "fmt"
    "net/http"
    "io/ioutil"
  )
  
  func main() {
  
    url := "https://www.netappspay.com/pg/api/v1/transaction/status/NT-28e275b3e5a998"
    method := "GET"
  
    client := &http.Client {
    }
    req, err := http.NewRequest(method, url, nil)
  
    if err != nil {
      fmt.Println(err)
      return
    }
    req.Header.Add("Authorization", "Bearer 4c219509e1ad4629823a91255bd7b477")
  
    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))
  }

var headers = {
  'Authorization': 'Bearer 4c219509e1ad4629823a91255bd7b477'
};
var request = http.Request('GET', Uri.parse('https://www.netappspay.com/pg/api/v1/transaction/status/NT-28e275b3e5a998'));

request.headers.addAll(headers);

http.StreamedResponse response = await request.send();

if (response.statusCode == 200) {
  print(await response.stream.bytesToString());
}
else {
  print(response.reasonPhrase);
}

import requests

  url = "https://www.netappspay.com/pg/api/v1/transaction/status/NT-28e275b3e5a998"
  
  payload={}
  headers = {
    'Authorization': 'Bearer 4c219509e1ad4629823a91255bd7b477'
  }
  
  response = requests.request("GET", url, headers=headers, data=payload)
  
  print(response.text)

Let's take a closer look at the request

The NT-28e275b3e5a998 in the path of the url is the txRef which serves as a unique identifier for the transaction.It is required to verify a transaction
