Control Foobar with Node Red by API

[Barabba11]

Hi, I'm not a guru of http and I don't now how to POST the tigh commands, I've searched around on issues for a possible solution bu can't find it, sorry.
Actually I can clear a playlist http://127.0.0.1:8880/api/playlists/0/clear and start play http://127.0.0.1:8880/api/player/play, but I can't figue out how to load a playlist, I've tried http://127.0.0.1:8880/api/playlists/add/:radio_alternative.m3u: while this m3u file is located in the music folder declared.

I also need how to change volume by api, I can't understand how to send parameters written on yml

Thank you a lot!

Uhm that link doesn't point to any way to load the m3u file, unless I miss something.
