HTTP Blueprint WebCommunication

Documentation

Communicate with a Webserver via Blueprints. You can send Data to a HTTP or HTTPS Webserver via GET or POST and get a String Array back. Each Line in the Server Response is one Array Value. Since Version 1.2 File Upload support. I recommend my JSON plugin for data communication. You don’t need C++.

Third-party websites may have security mechanisms (Captchas, Cookies) to block plugins like this. Check this beforehand or use your own server. Exceptions to this rule are HTTP/HTTPS APIs which are provided for this purpose. But Google Drive (Download) is since Version 1.8 supported. Tested on: Windows 10, Android 9 (Redmi Note 8T). IOS 12.1.2 (iPhone 5s)

I don’t like special sales. My prices are low all year round.

Nativization may cause problems and should be disabled in BPs that use this plugin.
