Remote API/Calls

I've been using an app on my Android called unified remote (https://www.unifiedremote.com/).  It has the ability to create custom remotes for Windows, Mac and Linux computers.  One of the things I love with it is that I can create my own custom Widgets with controls from multiple things.  I'd like to build an OpenLP remote with it, but not sure where to find a reference to how to do so.   The Android app is great, but I'd like to create a more customized one that I can add a few other windows buttons to (volume controls, etc).

OpenLP doesn't currently expose a way to control the volume remotely. Also, from an initial poke at UnifiedRemote for VLC, it just focuses the VLC window and presses keys and shortcuts -- hardly any real integration happening there.

I know OPenLP doesn't allow that, but Unified Remote does.  And it can handle more than key presses and short cuts, among the things it can handle are HTTP requests, which I presumed was how OpenLP's remotes communicate with the program.  What I'm hoping to do is create a server in Unifed Remote to work with OpenLP by passing the commands to OpenLP, so I can create a custom remote on my control android that does multiple things.  Right now I have one that works, but only if OpenLP is the active window (using key press sends).  If I could use HTTP requests instead, then it wouldn't have to be the active window.

If you have the web remote enabled you can control all sorts such as:

http://IP:4316

/api/display/desktop;; (desktop/blank/show)

/api/service/previous

/api/service/next

/api/controller/live/previous

/api/controller/live/next

From an old scirpt you can see here how I set a particular page or service item:

set_track() {
curl -s --get "http://openlp:password@host:4316/api/service/set" --data 'data={"request":{"id":'$(($1-1))'}}'
}

set_page() {
echo SET $1
curl -s --get "http://openlp:password@host:4316/api/controller/live/set" --data 'data={"request":{"id":'$(($1-1))'}}'
}

If you run Node-Red I can paste some NR nodes that we use.
