Variable (or dynamic value) in API URL

Hey everybody

I am querying an API via App Connect for some stock news and the symbol is apart of the URL, and not a traditional query parameter (e.g: ?symbol=aapl). I want the symbol to be based off of an input field so I can filter a Data View later on. Is this possible with App Connect API Source or do I have to do this using the Server Connect Add API Action?

The highlighted portion of the URL needs to be dynamic based on the input field. Does anyone have an idea on how this might be accomplished? If it isn’t possible via App Connect, some tips on doing it with Server Connect would also be great!
