    Do you really need to write your own client from scratch building WebRequests, etc.? Why not use an existing client like SpotifyAPI-NET?

    I'm trying to call the spotify API with C#. Unfortunately, I'm already stuck with getting the access token. This is how I tried to get it: private static async Task<string> GetAccessToken () { SpotifyToken token = new SpotifyToken (); string postString = string.Format ("grant_type=client_credentials"); byte [] byteArray = Encoding.UTF8.GetBytes (postString); string url = "https://accounts.spotify.com/api/token"; WebRequest request = WebRequest.Create (url); request.Method = "POST";

    Just encode your App ClientId and ClientSecret:

    var token = Convert.ToBase64String(Encoding.UTF8.GetBytes(string.Format("{0}:{1}",this.CliendId,this.ClientSecret)));
    

    Replace properly:

    request.Headers.Add("Authorization", "Basic " + token);
    

    That's it!

    This is the call that starts the process of authenticating to user and gets the user’s authorization to access data. The second call is to the Spotify Accounts Service ‘/api/token’ endpoint, passing to it the authorization code returned by the first call and the client secret key. This call returns an access token and also a refresh token.

    Based on simple REST principles, the Spotify Web API endpoints return JSON the type of resource; that information is provided elsewhere in the call.

    In order to get this result, we need to call two different endpoints in the Web API: Endpoint 1: a list of playlists for a certain user. GET https://api.spotify.com/v1/users/ {user_id}/playlists. Endpoint 2: the details of a playlist. GET https://api.spotify.com/v1/users/ {user_id}/playlists/ {playlist_id}

    Anyway, you can see how they do it, on GitHub:

    Create 3 files under the root of the project, client_id.txt, client_secret.txt, and refresh_token.txt, containing the values you acquired previously. The test cases should be able to use them to sucessfully authenticate with Spotify and make calls to the API. To run the test cases, simply use. make test.

    You will use your Spotify account credentials to sign in. One will be an API client to access the API, one will call the client and

    We will need these to generate an access token that we will use to pull in data from the API. We will break our code up int o three separate scripts. One will be an API client to access the API, one will call the client and generate an interface in Streamlit and one will be used to help with the look of the Streamlit interface.

    First, set up a Dev account with Spotify to access their Web API here. sure to explicitly refer to your access token in each subsequent function call.

    An R wrapper for pulling data from the 'Spotify' Web API in bulk, refer to your access token in each subsequent function call.
