Allow remote control via HTTP

There’s a setting in the Services section of Preferences called “Allow remote control via HTTP”. I assume this allows you to send commands to an open port on the OpenPHT client to control Plex.

Is there an API or Wiki anywhere that explains how to use this functionality?

I’ve seen various software remotes out there that rely on this feature for Kodi or Plex but I’m interested in learning how it works. Any help would be appreciated.

OpenPHT is listening on port 3005 for JSON API requests …
