Download: ASP.NET mvc4: Get response from after payment (Auto redirect)


                 In this post we will learn how to get response from Authorize.Net credit card payment using ASP.NET MVC4

One of my client projects I need to implement payment gateway. So just implemented using SIM (Server Integration Method). But my client wants, if the payment getting success then shown a custom receipt page and save the transaction details in to our own database. In other case if the payment getting fail then provides repayment option.

In SIM method this is not possible (or not advisable) because we using “x_relay_response” to get response from Note,this is just relay the url, not redirect to the result page. And URL always points to the And the response time also only 10 seconds. If your server not responds within 10 seconds then you get time out error like

“An error occurred while trying to report this transaction to the merchant. An email has been sent to the merchant informing them of the error. The following is a result of the attempt to charge your credit card.”

This error indicates that Authorize.Net is unable to connect to the page that you have specified as your relay response URL. To avoid this kind of errors you need to go with’s another one integration method AIM (Advanced Integration Method)

You can get more about AIM method from here

Implement  AIM :
First create a sandbox account in Authorize.Net. After you registered you will get the API Credentials

API Login ID
Transaction Key
Secret Question

Create you view page as per your requirement. Here I'm taking from default payment screen

Then add that details  into your web.config file

<!-- Payment Authorize.NET - Begins --> <add key="Payment.AuthLoginID" value="XXXXXXXXXX" /> <add key="Payment.AuthTransactionKey" value="XXXXXXXXX" /> <add key="Payment.TestMode" value="true" /> <add key="Payment.URL" value="" /> <!--<add key="Payment.URL" value="" />--> <!-- Payment Authorize.NET - End -->

Then call the following function into your post method

private string AuthorizePayment(PaymentDataModel payDataModel)
            string AuthNetVersion = "3.1"; // Contains CCV support
            string AuthNetLoginID = System.Configuration.ConfigurationManager.AppSettings["Payment.AuthLoginID"].ToString();
            string AuthNetTransKey = System.Configuration.ConfigurationManager.AppSettings["Payment.AuthTransactionKey"].ToString();

                objRetVals = System.Text.Encoding.ASCII.GetString(objRetBytes).Split(",".ToCharArray());

                if (objRetVals[0].Trim(char.Parse("|")) == "1")

Solution:Error during serialization or deserialization using the json javascriptserializer. the length of the string exceeds


           "Error during serialization or deserialization using the json javascriptserializer. the length of the string exceeds kendoui" I faced this error in Kendo-Grid.

            This exception is raised when the length of the data serialized as JSON exceeds the default MaxJsonLength. It means  The JavaScript Serialization settings allow maximum 2097152 character by default. But getMethod return string larger then this then it throw above error.

             According from the documents There are few possible solutions available to fix this issue

  • Setting the MaxJsonLength property default value within your web.config
  • Return a custom action result
  • Setting the MaxJsonLength property of a JavascriptSerializer object to perform your serialization.
  • Enable paging by calling the Pageable method
  • Use a View Model to serialize only the required properties of your model

Solution 1: Setting the MaxJsonLength property default value within your web.config
                       The MaxJsonLength property which can be set within the web.config of your application controls the maximum size of the JSON strings that are accepted by the JsonSerializer class. The default value is  2097152 characterswhich is equivalent to 4 MB of Unicode string data.

                   This will only apply to web-services that handle JSON.

 You can just copy and paste the following code to your web.config file to increase the size of this value 

      <jsonSerialization maxJsonLength="2097089" />

Solution 2: Return a custom action result

public ActionResult Read([DataSourceRequest] DataSourceRequest request)
    var data = GetData();
    var serializer = new JavaScriptSerializer();
    var result = new ContentResult();
    serializer.MaxJsonLength = Int32.MaxValue; // Whatever max length you want here
    result.Content = serializer.Serialize(data.ToDataSourceResult(request));
    result.ContentType = "application/json";
    return result;

Solution 3: Setting the MaxJsonLength property of a JavascriptSerializer object

                Using an instance of a JavascriptSerializer will not actually inherit the previously defined within the web.config (as the web.config only applies to Web Services that handle the JSON) so you can easily just create an instance of the serializer and set the property accordingly :

//Creates an instance of your JavaScriptSerializer and Setting the MaxJsonLength
var serializer = new JavaScriptSerializer() { MaxJsonLength = 86753090 };

//Perform your serialization
serializer.Serialize("Your JSON Contents");

This will allow you to easily your larger data and adjust your maximum size easily.

Difference between jQuery .bind() vs .live() methods


                     The .bind() method registers the type of event and an event handler directly to the DOM element in question. This method has been around the longest and in its day it was a nice abstraction around the various cross-browser issues that existed. This method is still very handy when wiring-up event handlers, but there are various performance concerns as are listed below.

The .bind() method will attach the event handler to all of the anchors that are matched! That is not good. Not only is that expensive to implicitly iterate over all of those items to attach an event handler, but it is also wasteful since it is the same event handler over and over again.

                     This methods works across various browser implementations.
It is pretty easy and quick to wire-up event handlers. The shorthand methods (.click(), .hover(), etc...)  make it even easier to wire-up event handlers. For a simple ID selector, using .bind() not only wires-up quickly, but also when the event fires the event handler is invoked almost immediately.

             The method attaches the same event handler to every matched element in the selection.
It doesn't work for elements added dynamically that matches the same selector.
There are performance concerns when dealing with a large selection.
The attachment is done upfront which can have performance issues on page load.


              The .live method attaches the event handler to the root level document along with the associated selector and event information. By registering this information on the document it allows one event handler to be used for all events that have bubbled (a.k.a. delegated, propagated) up to it. Once an event has bubbled up to the document jQuery looks at the selector/event metadata to determine which handler it should invoke, if any. This extra work has some impact on performance at the point of user interaction, but the initial register process is fairly speedy.

              The good thing about this code as compared to the .bind() example above is that it is only attaching the event handler once to the document instead of multiple times. This not only is faster, but less wasteful,

              There is only one event handler registered instead of the numerous event handlers that could have been registered with the .bind() method.The upgrade path from .bind() to .live() is very small. All you have to do is replace "bind" to "live". Elements dynamically added to the DOM that match the selector magically work because the real information was registered on the document. You can wire-up event handlers before the document ready event helping you utilize possibly unused time.

               This method is deprecated as of jQuery 1.7 and you should start phasing out its use in your code.
Chaining is not properly supported using this method.
The selection that is made is basically thrown away since it is only used to register the event handler on the document.

               Using event.stopPropagation() is no longer helpful because the event has already delegated all the way up to the document.Since all selector/event information is attached to the document once an event does occur jQuery has match through its large metadata store using the matchesSelector method to determine which event handler to invoke, if any.
Your events always delegate all the way up to the document. This can affect performance if your DOM is deep.
