Hello Guys, I keep getting the error The request was aborted: Could not create SSL/TLS secure channel. when i try call the service. however it works fine when i call the service using soupUI. I am using C# downloaded code to test Visa Direct API.

Hi 

Did you find the solution for the above error. I am also facing the same issue where I am getting error saying "The request was aborted: Could not create SSL/TLS secure channel." I have tried all the options but no luck.

Its working fine with SOAP UI, but when I try with .NET its not working. Can you please help me on this issue.?

 string requestURL = "https://sandbox.api.visa.com/vdp/helloworld";// ConfigurationManager.AppSettings["visaUrl"] + path;
            string userId =  ConfigurationManager.AppSettings["userId"];
            string password =  ConfigurationManager.AppSettings["password"];
            string certificatePath = ConfigurationManager.AppSettings["cert"];
            string certificatePassword = ConfigurationManager.AppSettings["certPassword"];
            string statusCode = "";
            LogRequest(requestURL, requestBodyString);
            // Create the POST request object

            ServicePointManager.Expect100Continue = true;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
            HttpWebRequest request = WebRequest.Create(requestURL) as HttpWebRequest;
            request.Method = method;

            if (method.Equals("POST") || method.Equals("PUT"))
            {
                request.ContentType = "application/json";
                request.Accept = "application/json";
                // Load the body for the post request
                var requestStringBytes = Encoding.UTF8.GetBytes(requestBodyString);
                request.GetRequestStream().Write(requestStringBytes, 0, requestStringBytes.Length);
            }

            if (headers != null)
            {
                foreach (KeyValuePair<string, string> header in headers)
                {
                    request.Headers[header.Key] = header.Value;
                }
            }
           
            // Add headers
            request.Headers["Authorization"] = GetBasicAuthHeader(userId, password);
           request.Headers["ex-correlation-id"] = GetCorrelationId();
           
            // Add certificate
            var certificate = new X509Certificate2("C:\\OpenSSL\\bin\\BillPay.p12", "test");
            request.ClientCertificates.Add(certificate);
            request.PreAuthenticate = true;
           
            try
            {
               
                // Make the call
                using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
                {
                    LogResponse(testInfo, response);
                    statusCode = response.StatusCode.ToString();
                }
            }
            catch (WebException e)
            {
                if (e.Response is HttpWebResponse)
                {
                    HttpWebResponse response = (HttpWebResponse)e.Response;
                    LogResponse(testInfo, response);
                    statusCode = response.StatusCode.ToString();
                }
            }
 

Thanks,

Hi @ramesharige,

If you are using C# please make a p12 file using the commands from github
https://github.com/visa/SampleCode/tree/master/vdp-c-sharp#usage

You can also refer to manual
https://github.com/visa/SampleCode/wiki/Manual

The problem could be that you have made a wrong p12 certificate.

[ramesharige]

Thanks those links helped me. So we need to make sure to generate certificate differently if we are using c#.net

Hi Dana

Thanks for your URLs, It worked like charm when I followed those instructions.

It was not working when I tried first time. Again I tried to generate with help of your URL's it worked. Thanks alot.

Thanks,

Ramesh

Those links no longer work, do you have an updated url?

Hello @appdevelopers, 

Due to some security issues, we are not able to upload the code on GitHub. VDP engineering team is workin on this but meanwhille, you can create a project on VDP and get the sample code from the Test Data of the project. 

Please follow the steps in the “Get Started” link below to register and create a Visa Developer application.  

https://developer.visa.com/pages/working-with-visa-apis   

  

This guide walks you through the key steps for application creation, credentials, and connection validation.  

  

If you are ready after testing your App in sandbox, send us a production request and we will evaluate your Application and other credentials.   

  

Let me know if you have any additional questions. 

Thank you, 

Vaibhav

I tried different openssl commands to generate the p12 certificate and found that the following works for me:

> openssl pkcs12 -export -in cert.pem -inkey "privateKey.pem" -out myProject_keyAndCertBundle.p12

See my post on a different thread for more information:
