Re: Foreign Exchange Rates API

Hi,

 

This error ususally happens when Client certificates not sent along with the request because of networking issues on the client side. If the same .p12 is working fine with SOAP UI, then we need to look at the code on how it is being called from the code. Can you please share your test class so we can take a look at the code on the .p12 is being refernced. If you have difficulty posting the code here, please share it to developer@visa.com, so we can get back to you accordingly.

 

Thanks,

Jai

Re: Foreign Exchange Rates API

Hi Jai,

Thanks for your response.

I'm sending the client certificates from SOAP UI, it's worked there.

When I;m sending the same certificates from Code, it's not working.

I'll share the code by E-Mail, kindly look.

Thank you in advance.

 

Regards

Murali

Re: Foreign Exchange Rates API

Hi Murali,

 

Since you are using C#,  please try rebuilding key certificate bundle for .NET developers. Note there is no -certfile attribute in the below command.

 

Sample command below

$ openssl pkcs12 -export -out myProject_keyAndCertBundle.p12 -inkey key_63973e0f-6bae-4ae0-98b9-5f6tg153ce2e.pem -in cert.pem

 

Thanks,

Jai

Re: Foreign Exchange Rates API

Hi Jai,

Thank you for response.

Unfortunately, this solution is also not working with C# code.

        I've generated p12 certificate by using openstool with follwing command.

       openssl pkcs12 -export -out myProject_keyAndCertBundle.p12 -inkey key.pem -in cert.pem

        I'm sending myProject_keyAndCertBundle.p12 certificate as following.

        X509Certificate2 certificate = new X509Certificate2(certificatePath, certificatePassword);
        ServicePointManager.Expect100Continue = true;
        System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
        request.ClientCertificates.Add(certificate);
        request.PreAuthenticate = true;

        But It's returning same reponse as Bad Request-400.

Thanks,

Jai

Re: Foreign Exchange Rates API

Hello,

I tried using the API on my website  and getting  issues like My users are saying that they are having issue while changing currency or paying via Card. Any solution for that?
