Using NAV CU1290 SOAP Web Service Request Mgt. to connect with a server using a self-signed certificate - HttpWebRequest.GetResponse Error "The remote certificate is invalid according to the validation procedure."

Working in NAV 2017, I'm trying to use CU1290 SOAP Web Service Request Mgt. to send a request and get a response from a server using a self-signed certificate. I've installed the certificate on the server with certlm in Trusted Root Certificate Authorities. I can make the request through my browser (which does still show a certificate error) but calling through the NAV library and eventually DotNet's System.Het.HttpWebRequest.GetResponse, I get the failure message "The remote certificate is invalid according to the validation procedure."

I see from the DotNet forums that you can override the certificate validation logic by installing a callback for ServicePointManager.ServerCertificateValidationCallback (https://stackoverflow.com/questions/1189897/net-programming-what-to-validate-on-an-ssl-self-signed-certificate).

The problem is, I can't figure out how to load a callback from within C/AL. Is this possible? Is there another way to disable the certificate test, ideally on a call-by-call basis? Should I just do all this in DotNet and give up on CU1290?

Try DisableHttpsCheck:

WebServReqMgt.SetGlobals(ReqBodyInStream,Url,Username,Password);

WebServReqMgt.DisableHttpsCheck;

WebServReqMgt.RUN;

// get the response

WebServReqMgt.GetResponseContent(RespBodyInStream);

ResponseXmlDoc := ResponseXmlDoc.XmlDocument;

ResponseXmlDoc.Load(RespBodyInStream);

MESSAGE(ResponseXmlDoc.InnerXml);

that won't work using cu 1290 and .net class httpwebrequest.

as you found also out, what you need for certificates like that is following c# code in nav:

System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate(Object obj, X509Certificate X509certificate, X509Chain chain, System.Net.Security.SslPolicyErrors errors)

{

return true;

};

that's not possible in nav.

i had that issue, developed then a .net lib for the complete web service call in c#.

Thanks for your prompt response, Stefano. I did have DisableHttpsCheck, but that didn't help. I believe that DisableHttpsCheck is intended to permit use of http (instead of requiring https.) My problem is that the target services was https using a self-signed certificate.
