How to implement Spotify

I was able to finally call the favorites and the sonos playlist, now im looking on how to receive playlist from spotify and play a specific song in the playlist

Spotify app on any phone to target Sonos speaker. Job done.

Eh eh eh, I will like it if it was in that way but we are developing an app that includes all the service between those there is sonos with playback of spotify songs…. Do youhave any other idea?

I want to do the same stuff that SONOS S1 app does, connect the spotify service somehow and play audio on sonos. There is a way using API (reading on stack it seems that there isnt a way to do this), if not what should I use to do this? UPnP, using loadAudioClip and grab in some way a streamUrl from Spotify?
Super thank you boss

1. Obtain key and token for the user’s Spotify account from the Sonos system (very hard)
2. Use SMAPI to connect to Spotify and enumerate the playlists (easy if you know REST)
3. Pick one and take the url and pass it to AVTransport1.SetNextAVTransport (UPNP call to speaker) (trivial if you know UPnP)

No idea if you could replace #3 with loadAudioClip

Just to note that playing local files (e.g., from USB drives) on Sonos is one of the features offered by SoCo-CLI. It works just as @controlav describes, but is implemented in Python:

Also, we’re currently working on music service (re)enablement in SoCo. It’s tricky, but once it’s available, I’ll add it to SoCo-CLI.

Im bonded to C# I cant use python unfortunately

1. I have access to user’s spotify account (in order to create key and secret) so I guess the point 1 can be skipped?

2. I read the SMAPI doc here: SMAPI but there isnt a call that retrieve an URL except for the getMediaURI that seems to return an URI to the stream, but there isnt the Endpoint indicated in the SMAPI.
3. I dont know UPnP and I was searching for some lib for C# but I dont find nothing easily to use. Can you give me an example of URL to pass to the SetNextAVTransport?
   
   If can help I have full access to SONOS and SPOTIFY user’s account
   Thank you, you are kind and helpful.

1. I don’t think you can take the key and secret from the Spotify and pass them to SMAPI, but I never tried it, so worth a shot
2. getMetadata is the call you need, starting at “root” and navigate through that so you can get to the user’s playlists. Once you have done that once, you will probably find a fixed id for users playlists and can go straight to it.
3. There are lots of UPnP APIs for C# around (I have not used any of them), and if on Windows you can use the built-in OS support for it (which I last used about a decade ago).

Actually i misspoke: for a Spotify playlist you will need to AddURIToQueue not SetNextAVTransport. The URI would be something like "x-rincon-cpcontainer:0006008cspotify%3aplaylist%3a3irbM1vEqph2KusCP" and the metadata would be a basic DIDL-lite structure containing an id similar to the url (but different). All of this is trivial to see by taking a network capture of the Sonos app starting a Spotify playlist.

1. If I cant pass data to the SMAPI how can I use this SMAPI? I look for an endpoint of the SMAPI and I didnt find it. The unique sneak I found is this:

   

   but this page is no longer accessible. If I understand correctly the SMAPI server is something that I need to create and host and then this server redirect the REST call to the music service using their API, is it correct? That’s why there isnt an endpoint on SMAPI DOC?

2. Ok

3. I tried some but no documentation at all so it’s tricky

4. You talk about capture a frame form the sonos app, how can I accomplish this, I was thinking about wireshark but my pc is wired so Im not sure I can get the frame that start from my phone and I guess they are encrypted.
   Thank you
