Http Request to download Text File

Hello Im trying to read a text file from a dropbox link or server. I want to read that text file to retrieve some data for an ios and android app that I am make. Im not good with c++ but need a code that can do this… I was reading and believe its done using the TSharedRef but I dont know how to use it.
All help is appreciated!!

UE4 provides HTTP client APIs in HTTP module, i made rough instructions how to do it in other question like that:

Hi,
I recently made a plugin that allows you to download files to a device from a URL over HTTP. It’s completely free.
Here is the link: GitHub - gtreshchev/RuntimeFilesDownloader: Runtime Files Downloader plugin for Unreal Engine. Downloading files over HTTP / HTTPS at runtime.
