Invoking/visiting a URL from PLP?

Hi,

I'm quite new to PLP so please bear with me and let me know if you need more information.
I'm trying to perform an action on a webpage by invoking/visiting a URL from PLP using a GET request with the HTTP connector component. When running the pipeline, the component will pass but, the action hasn't been performed on the webpage.

I've tested that the URL that is being passed into the component is correct (and that it is a get request) by visiting the URL manually using Microsoft Edge with DevTools open and checking that it performs the expected action. Is this the right component to be using for this? Or would anyone be able to suggest some troubleshooting actions please?

Many thanks
Andy
