.net integration

Hi Jitender,

Unfortunately, we do not have an example of using Payeezy.js with asp.net and C# yet.

Once you have the token, the next step is to call the Token Based Payments method. You can view all the details here- https://developer.payeezy.com/payeezy_new_docs/apis/post/transactions-2

Do let us know how we can help further.

Hi Jitender,

Yes, you will need enable TransArmor for your sandbox app as well. To do this, go to My APIs --> select your app --> Entitlements --> Add Entitlements --> Check Payeezy and TransArmor --> Save.

Do let us know if you have more questions.

Hi Jitender,

Here is a sample code in C# to generate HMAC.

        Random random = new Random();
        string nonce = (random.Next(0, 1000000)).ToString();

        DateTime date = DateTime.UtcNow;
        DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0);
        TimeSpan span = (date - epoch);
        string time = span.TotalSeconds.ToString();
        
        string token = Request.Form["token"];//Merchant token
        string apiKey = Request.Form["apikey"];//apikey
        string apiSecret = Request.Form["apisecret"];//API secret
        string hashData = apiKey+nonce+time+token+jsonString;
        
        string base64Hash = Convert.ToBase64String(CalculateHMAC(hashData, apiSecret));

Hi Guys!
Happy news. Finally I could manage to integrate the API with c#. Following is the code.

private void TestPayeezy()
{
var builder = new StringBuilder("{ " +
"\"merchant_ref\": \"Acme Sock\", " +
"\"transaction_type\": \"authorize\", " +
"\"method\": \"credit_card\", " +
"\"amount\": \"1299\", " +
"\"currency_code\": \"USD\", " +
"\"credit_card\": { " +
" \"type\": \"visa\", " +
" \"cardholder_name\": \"John Smith\", " +
" \"card_number\": \"4788250000028291\", " +
" \"exp_date\": \"1020\", " +
" \"cvv\": \"123\" " +
"} " +
"}");
var payload = builder.ToString();
byte[] byteArray = Encoding.UTF8.GetBytes(payload);
var apiKey = "XXXXXXXXXXXXXXXXXXXXXX";
var timeStamp = ((long)(DateTime.UtcNow - new DateTime(1970, 1, 1)).TotalMilliseconds).ToString(CultureInfo.InvariantCulture);
var nonce = (10000000000000000000 * new Random(DateTime.Now.Millisecond).NextDouble()).ToString("0000000000000000000");
var merchantToken = "xxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
var secretKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

var post = (HttpWebRequest)HttpWebRequest.Create("https://api-cert.payeezy.com/v1/transactions");
post.Method = "POST";
post.KeepAlive = true;
post.Accept = "*/*";
post.Headers.Add("Accept-Encoding", "gzip");
post.Headers.Add("Accept-Language", "en-US");
post.Headers.Add("apikey", apiKey);
post.Headers.Add("nonce", nonce);
post.Headers.Add("timestamp", timeStamp);
var authorize = CreateHMAC(apiKey, secretKey, merchantToken, payload, nonce, timeStamp);
post.Headers.Add("Authorization", authorize);
post.ContentType = "application/json";
post.Headers.Add("token", merchantToken);
post.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7";
post.GetRequestStream().Write(byteArray, 0, byteArray.Length);
var response = post.GetResponse();
var reader = new StreamReader(response.GetResponseStream());
var responseFromServer = reader.ReadToEnd();
}

public static string CreateHMAC(string apiKey, string apiSecret, string token,
string payload, string nonce, string timeStamp)
{
var hmacData = apiKey + nonce + timeStamp + token+ payload;
var hmac = new HMACSHA256(Encoding.UTF8.GetBytes (apiSecret));
var encBytes = hmac.ComputeHash(Encoding.UTF8.GetBytes(hmacData));
var encStr = ByteArrayToHexString(encBytes);
return Convert.ToBase64String(Encoding.UTF8.GetBytes((encStr)));
}

public static string ByteArrayToHexString(byte[] ba)
{
StringBuilder hex = new StringBuilder(ba.Length * 2);
foreach (byte b in ba)
hex.AppendFormat("{0:x2}", b);
return hex.ToString();
}

There was a temporary issue on our server for 1 hour today. It should be ok now.

Hello everybody, how to check my customer's purchase succeed in sandbox environment ???? I using asp.net.

You can query your sandbox transactions using the event search api - http://developer.payeezy.com/payeezy-api/apis/get/events

HI Team,

Could you please give me the working C# code for Credit/Debit card payment and Telecheck payment.

Bikram - Unfortunately, we do not have a C# library. Below is only a demonstration of a C# integration for a credit/debit card pre-authorize transaction.
