Payumoney Integration With Asp.Net MVC
PayuMoney-
It is a payments getway getting popular now a days. Actually there are few other payments getways like Stripe,Paypal. And PayuMoney is also getting more popular now a days.
So in this article we will learn how to do Payumoney Integration With Asp.Net MVC.
So for this puprpose you must have Client Key and Secret before starting integration of PayuMoney. You can go through https://www.payu.in/developer-guide. There you can generate merchant key for your project. After having merchant key and test credentials we can move to the next steps as described below:-
Step 1 : Paste the code in controller
So for this step we have to copy the Action method given below in our controller . Index method will be used to run the page. While Payment Success method will be called after the payment is successful and Payment Failed method will be called in case our payment transaction is failed.
Here we have to know about how those two actions will be hit. Those two will be passed in surl and furl. Which basically stands for success url and failure url.
surl- It is basically the url where you website will redirect after successfull payment. Or in short its the success url.
furl-It is basically the url where you website will redirect after failure of payment. Failure can happen due to wrong otp or wrong card details. So in that case it will go to furl.
Hash: PayuMoney actually expects few parameters as mandatory. And after surl,furl Hash is a mandatory parameter. It is basically a encrypted form of values. You can use the action provided in code snippet for generating hash.
Hash must be created based on following formula
sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||SALT)
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult PaymentSuccess()
{
var form = Request.Form.ToString();
ViewBag.mihpayid = Request.Form["mihpayid"].ToString();
ViewBag.paymentId = Request.Form["paymentId"].ToString();
ViewBag.mode = Request.Form["Mode"].ToString();
ViewBag.status = Request.Form["status"].ToString();
ViewBag.txnid = Request.Form["txnid"].ToString();
ViewBag.amount = Request.Form["amount"].ToString();
return View("PaymentSuccess");
}
[HttpPost]
public ActionResult PaymentFailed()
{
var form = Request.Form.ToString();
return View("Index");
}
public ActionResult Hash(string txnid, string key, string salt, string amount, string productinfo, string firstname, string email, string phone, string udf5,string udf1)
{
string d = key + "|" + txnid + "|" + amount + "|" + productinfo + "|" + firstname + "|" + email + "|"+ udf1 +"||||" + udf5 + "||||||" + salt;
return Json(GetStringFromHash(d), JsonRequestBehavior.AllowGet);
}
private static string GetStringFromHash(string text)
{
byte[] message = Encoding.UTF8.GetBytes(text);
UnicodeEncoding UE = new UnicodeEncoding();
byte[] hashValue;
SHA512Managed hashString = new SHA512Managed();
string hex = "";
hashValue = hashString.ComputeHash(message);
foreach (byte x in hashValue)
{
hex += String.Format("{0:x2}", x);
}
return hex;
}
Step 2: Add this script in _layout.cs.html
<script id="bolt" src="https://sboxcheckout-static.citruspay.com/bolt/run/bolt.min.js" bolt-color="e34524" bolt-logo="http://boltiswatching.com/wp-content/uploads/2015/09/Bolt-Logo-e14421724859591.png"></script>
Step 3: Paste the code in Index.cs.html
After completing the controller part. We can now move to the html side. So for using PayuMoney we have to create a form and have to add few mandatory fields there as explained in code snippet. And if you missed any of those your PayuMoney will not work.
TestUrl- https://test.payu.in/_payment
Production Url- https://secure.payu.in/_payment
We have to pass these url in action attribute of form
@{
ViewBag.Title = "Home Page";
}
<div class="jumbotron">
