First Data Global Gateway Integration in Asp.Net MVC C#


I have added a new Github repository for First Data Global Gateway Integration in Asp.Net MVC.  The sample provides a rest api implementation for credit card based payment processing. Since, I have choosen Asp.Net MVC empty project template you might need to install System.Net.HttpClient library from nuget.org or install directly from visual studio.

Command – Install-Package Microsoft.Net.Http

Download Location or copy paste the url

https://github.com/deepumi/FirstDataPaymentGateway-CSharp.Net

This code was taken from the original source https://support.payeezy.com/hc/en-us/articles/204699865-C-REST-Sample-Code-For-Use-with-v12-v13

Example Usage:

 var paymentService = new PaymentService("1.50", "0515","Card holder name","4111111111111111", "23".ToString()); //customer Id for Internal purpose to track which customer made the transaction...
 var transactionResult = await paymenetService.PostAsync();
 if (transactionResult == null) return;
 if (transactionResult.TransactionApproved && !transactionResult.TransactionError && transactionResult.CustomerRef == customerId.ToString())
 {
 //transaction success....
 }
 else
 {
 //transaction failed
 var message = transactionResult.Message;
 }

Configuration Settings:
Following values needs to be changed in the web.config file.

<add key="GATEWAY_ID" value="Exact ID" />
<add key="GATEWAY_PWD" value="Password" />
<add key="TRANS_TYPE" value="00" />
<add key="HMAC_KEY" value="HMAC Key" />
<add key="KEY_ID" value="Key Id" />
<add key="GATEWAY_URL" value="https://api.demo.globalgatewaye4.firstdata.com" />

Transaction Summary file(transaction_summary.xml) from payment gateway is included in the App_Data folder.

  1. I am trying to integrate your code but I am getting a null transaction result and no other error messages to go on. Please let me know if you can help.

      1. Deepu,

        I attempted to log the exception with:

        catch (Exception ex)
        {
        string filePath = @”E:\Errors\Error.txt”;

        using (StreamWriter writer = new StreamWriter(filePath, true))
        {
        writer.WriteLine(“Message :” + ex.Message + “” + Environment.NewLine + “StackTrace :” + ex.StackTrace +
        “” + Environment.NewLine + “Date :” + DateTime.Now.ToString());
        writer.WriteLine(Environment.NewLine + “—————————————————————————–” + Environment.NewLine);
        }

        }

        This does not create a file but i did put the following in the Homecontroller

        if (transactionResult == null)
        {
        ViewBag.Message = “Null Result”;
        return View();
        }
        And Null Result displays in the view.

        Thanks,
        Doug

      2. Doug,

        Can you see what is the value return in the out put variable *responseXml line no L 103 * ( https://github.com/deepumi/FirstDataPaymentGateway-CSharp.Net/blob/master/FirstDataPaymentSample/Api/PaymentService.cs )

        *Also, Change the below line and see what you are getting in **responseXml variable*

        * From *

        using (var response = await client.SendAsync(request).ConfigureAwait(false)) { if (response.StatusCode == System.Net.HttpStatusCode.Created || response.StatusCode == System.Net.HttpStatusCode.OK) responseXml = await response.Content.ReadAsStringAsync().ConfigureAwait(false); else

        LogStatusCode(response.StatusCode.ToString()); }

        To

        using (var response = await client.SendAsync(request).ConfigureAwait(false)) {

        *responseXml *= await response.Content.ReadAsStringAsync().ConfigureAwait(false);

        }

  2. Deepu,

    Thanks again for your help,

    Now I am getting Invalid signature received ‘WeXXO4############’.

    The signature changes on refresh.

      1. Hi Deepu,

        Everything working great but I was wondering if the status returned was not OK how would you pass the detail of the failure to the view?

        Thanks,
        Doug

  3. Hi,

    Thanks for your reply. I got the keys from Payeezy, but when i am running the app with test account always getting “transactionresult” as null. Do i need to change anything in the code.
    And one more thing, is customerId gave by user is mandatory.

    Thanks
    Vanaja

    1. If you are getting transaction result is null, you should debug and see what error you are getting. I have already mentioned in comment section for some one asking the same issue.

  4. Hi Deepu,

    I found the error as “StatusCode: 401, ReasonPhrase: ‘Unauthorized'”, i understand the reason is certificate has to be installed.Can you please provide me the guiding link for certificate installastion for Firstdata api.

    Thanks&Regards,
    Vanaja.M
