How do I view an existing feed?

[nmk]

Hello,

I was recommended Soap UI to view an existing feed. I don't need to import, test or edit it; I just want to be able to see the contents. I have a url for the feed and an API key, and have been told to use the header "Accept: application/xml". However I have no idea where to start with this software and would appreciate some pointers please!

Thanks

If you need to make an HTTP request, to configure its attributes and to execute it, then HTTP Test step might be sufficient:

Also, there's a beginner's guide, it might help you to get more familiar with SoapUI: https://www.soapui.org/getting-started.html
