Calling the mvisa merchantpushpayments API from BizTalk 2013

Morning Guys

Please could you help me, I’m trying to call your visa  merchantpushpayments API from BizTalk 2013 and I’m getting this error:

System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority 'sandbox.api.visa.com'. ---> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

   at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)

   at System.ServiceModel.Channels.HttpChannelFactory`1.HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse(IAsyncResult result)

   --- End of inner exception stack trace ---

Server stack trace:

   at System.Runtime.AsyncResult.End[TAsyncResult](IAsyncResult result)

   at System.ServiceModel.Channels.ServiceChannel.SendAsyncResult.End(SendAsyncResult result)

   at System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result)

   at System.ServiceModel.Channels.ServiceChannel.EndRequest(IAsyncResult result)

Exception rethrown at [0]:

   at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)

I, have been able to call the API successfully from SOAP UI but its seems to be a challenge to get it to work using BizTalk’s WCF Adapters.

I’ve so fare enabled TLS 1.1 / TLS 1.2 in the Regestry as well as installing CU7 for BizTalk Server 2013

Hey @gavinbrummelkam,

To resolve the error, please create new .p12 using the command line below.
 
Command line:
openssl pkcs12 -export -out p12certfile.p12 -inkey example-key.pem -in cert.pem
 
Then please try to call the helloworld method and see if you get a successful response.
