Sure, i can share. Would the python action be sufficient? My App is quite crowded with several things (Spotiy, MPC/MPC, OpenHab, etc…) and actually its in german.
Here is a link to the basic action code: https://github.com/Padishar24/SnipsOpenHab/blob/master/spotify.zip
You’ll find more information how accessing spotify works under the project “spotipy”. Please google it.
Some few points of interest:
The login token is stored in the config.ini of your app / skill. I recommend to run at least one command manually from a python console startet from you skills folder under user _snips-skills as you need to open a url to grant snips access to spotify. This URL will be printed during the first login. The resultung redirected url need to be entered.
Maybe next year i’ll have some spare time to create a proper skill, if Snips is then still be public.
