My Question or Issue

I am developing an app with React-native and i need to use the spotify API. Even though I authorise the app to use my account i don't get back an access token.

You can find only the client id and client secret there. You can also add redirect uris there.

The next step in getting an access token, you can find here: https://developer.spotify.com/documentation/web-api/concepts/authorization

I have already seen the website. I have added to my code this part 

class AuthenticationHandler {

  constructor() {

    this.spotifyAuthConfig = {

      clientId: "[client id]",

      clientSecret: "[clientsecret]",

      redirectUrl: "[redirect uri]",

      scopes: [

        "playlist-read-private",

        "playlist-modify-public",

        "playlist-modify-private",

        "user-library-read",

        "user-library-modify",

        "user-top-read",

      ],

      serviceConfiguration: {

        authorizationEndpoint: "https://accounts.spotify.com/authorize",

        tokenEndpoint: "https://accounts.spotify.com/api/token",

      },

    };

  }
And nothing happens. Can you help me?

I can only redirect you to https://developer.spotify.com/documentation/web-api/tutorials/code-flow

I haven't used JavaScript in combination with the Spotify Web API before.
