Description

Communicate with a Webserver via Blueprints. You can communicate with an HTTP/HTTPS web server via GET, POST, PUT, HEAD.

Download and upload files. Option to split files to bypass limitations. Google Drive (Download) is since Version 1.8 supported.

I recommend my JSON plugin for data communication. You don't need C++.

Tested on: Windows 10-11, Android 9-16. IOS 12.1.2 (iPhone 5s), Mac OS 10-15
