Simple Http request

Hello,

My marketing department has a requirement to do a simple pull of activities from Constant Contact.  What I was hoping to do is a simple http pull request using Power Automate....don't need a big integration....just want to pull some activities and contacts.

I tried to use the HTTP request and could not find exactly how it needs to be set up.

Can anyone give me examples of what info I would need to supply to do this?

If not possible with Power Automate, is there a function in CC that allows me to setup a nightly dump somewhere?

Thanks.
