creating backend that holds spotify connection "infinitely"

[adammo94]

Ok, so basically I'd like to achieve similar functionality as e.g. last.FM has (one time user account - spotify account tie) From what I've read the way to do it is to use Authorization code without PKCE. Can anyone point me any further? I have firebase authentication in my app. Should I put anything what comes from spotify into user firestore databse and then use it?

You could look into using firebase functions: https://github.com/firebase/functions-samples/tree/main/spotify-auth
