Download file from portal

Is it possible to use HTTP Request in order to download a specific file from a portal like Dropbox, GDrive etc.?
I had gone through a documentation explaining the way to download any specific web image and therefore was wondering if the same technique or something else might be helpful to download required files from these portals.

I had tried from Dropbox but I don’t think it is working.


Assuming there are APIs available which of course things like Dropbox will have, then yes you can authenticate and call HTTP requests against them.
