API SSL connection Issue - Could not create secure SSL/TLS channel

[Nandhakumar626]

Hi,

I'm currently working with an API which is 3rd party and we have credentials and setup done from the bot to make request. I have tried a test request to api and get the response back via SOAPUI.

But when i tried the same via blueprism, getting the below error. Can anyone help if you have faced the same?

I have created an API under System>Objects>Web API Services. This api needs certificates to be loaded with key to create a 2way SSL connection with API.

Now the api source has given a C# code to create a 2 way SSL connection via code stage as below, tried the same in code stage, by passing the parameters required.

using System.Net;

using System.Security.Cryptography.X509Certificates;

HttpWebRequest request = WebRequest.Create (requestURL) as HttpWebRequest;

// Add headers

string authString = userId + ":" + password;

var authStringBytes = System.Text.Encoding.UTF8.GetBytes (authString);

string authHeaderString = Convert.ToBase64String (authStringBytes);

request.Headers ["Authorization"] = "Basic " + authHeaderString;

// Add certificate

var certificate = new X509Certificate2(p12certificatePath, p12certificatePassword);

request.ClientCertificates.Add(certificate);

**Highlighted in bold are input parameters being passed to this stage.

Once this stage is executed, i'm trying to call a method that i have setup in blueprism but getting the below error.

I have loaded the same certificate file and key into SSL settings under preferences in SOAPUI and it worked. but via blue prism facing this issue.

Please guide me.
