I am trying to send a POST request to a SOAP API.

I have tested the request with POSTMAN and get return code 200.

When I do the same with Powerbuilder I get code 415.

I have compared the requests using Fiddler and they look exactly the same.

Same Headers, record length and body.

The Content-Type is application/soap+xml in both cases.

I have tried other content-Types - but always the same error 415.

So where can PB be different?

Where else can I look?

Any help would be appreciated.

Sorry to all.

I wrote Application instead of application.

Now it works.

Hi Frankel,

if you follow carefully this tutorial


you should be able to end up in a working client.

Please be sure you build correctly both http and soap headers, otherwise media type validation error will be issued by the server.

Thanks - I read the tutorial. The API that I am calling does not provide on line assistance.

But I managed to get it working with POSTMANl.

However, sending the same message in PB(2017) I get error 415.

I checked both transmissions using Fiddler and both seem to send the same thing.

Postman works and PB does not. ?

You'll probably need to post your Powerbuilder Code and your working Postman Configuration (showing all headers and body) before anyone will be able to help you
