Currently our app makes web calls using the Windows OLE object "WinHttp.WinHttpRequest.5.1".

I am looking into possible changing to HttpClient.

We are using the SetClientCertificate method which I don't see in PowerBuilder HttpClient. RestClient doesn't have it either.

Is there a way to accomplish this with the HttpClient object?

Hi Roland,

 

Thanks for reporting this problem.

Sorry to let you know that currently, HTTPClient and RESTClient don't support this feature.

However, the upcoming PB 2022 Beta will support it with the new SetClientCert method.

We will notify you when it is available so that you can try it out in advance.

 

Regards,

Hi Roland,

 Does this REST API offer Oauth also?  That may be a way around authenticating without using a certificate.  I've got a lot of experience working with REST APIs using Oath.  Lmk if you want to discuss.

The web api is by another department in the company so I can ask.

The problem turned out to be due to the payload being too large. It is in XML format. I suggested to them to allow for JSON which is much smaller. It is also transmitting all data every time rather than just what changed. The other department has control of the web api and the window in the desktop app that sends the data so it is up to them to fix.
