Hello everyone,

 

I am migrating a PB2019 application that uses SOAP to PB2022. As SOAP has been deprecated in PB2022 can anyone suggest a strategy to replace the SOAP code with REST API?

Thanks in advance.

Hi Chris, a follow up to this if you don't mind... I am a little new to SOAP, REST in PB.

 

HTTP Client can call SOAP API, is it possible to apply authentication on HTTP client call to SOAP API?

ie.

The existing EAS SOAP API below is using integrated windows authentication. is it possible to apply integrated windows authentication on HTTP client call to SOAP API?

conn = Create soapconnection

          TRY

                 conn.Useintegratedwindowsauthentication( True)

          CATCH (Throwable x)

                   ls_error = x.GetMessage()

                   MessageBox( "EAS", "Error initializing web service call to Universal Coder." )

                   RETURN -1

          END TRY

 Thank you. Much appreciated.

Hi David;

From the little that I know of your authentication "Use Case:" requirements .. I think that you might want to use the SetCredentials() command ...

The documentation Chris provided specifically points out that integrated windows authentication not supported for the HTTPClient.

Hi David,

Before the HttpClient object supports Windows authentication, could you use another supported authentication method? It usually depends on your Web Service.

If you have to use integrated Windows authentication, you can try some third-party HTTP Clients.

Such as ChilKat, refer to a similar topic here: https://community.appeon.com/index.php/qna/q-a/useintegratedwindowsauthentication-replacement-for-httpclient

If interested in .NET, you can also try the Calling the .NET Assembly feature (https://docs.appeon.com/pb2022r2/application_techniques/Calling_C_Assembly_in_an_Application.html) to leverage the other components from the .NET world.

Regards, Logan

Is it true that SOAP calls are deprecated in PB 2022? If we have interfaces with other vendor applications that still uses SOAP then how do we mitigate this issue?

No, you can still make SOAP calls. But the implementation has been changed. Now you need to use the HTTPClient. Here is article: https://community.appeon.com/index.php/articles-blogs/tutorials-articles/2-powerbuilder/236-call-soap-web-services-using-httpclient-object

Hi David,

This is a new area for me and I've been slowly trying to piece this together but did anyone ever provide a solution that worked for you? Could you share how you decided to handle this? I see windows authentication isn't supported by httpclient. Did you go with a 3rd party? Something like Visual Guard is far more than we need for this one thing and was wondering what worked for you? This is so specific and doesn't seem like a huge thing that should require more software.
