Add Track to Playlist

[SL99]

Hello everyone, 

i am trying to add some tracks to a spotify playlist of mine. But I always get the error Error: 401 Client Error: Unauthorized for url. Can someone help? Thank you 🙂

This is my code:

def get_auth_header(token😞

    return {"Authorization": "Bearer " + token}

def get_token():

    auth_string = CLIENT_ID + ":" + CLIENT_SECRET

    auth_bytes = auth_string.encode("utf-8")

    auth_base64 = str(base64.b64encode(auth_bytes), "utf-8")

    url = "https://accounts.spotify.com/api/token"

    headers = {

        "Authorization": "Basic " + auth_base64,

        "Content-Type": "application/x-www-form-urlencoded"

    }

    data = {"grant_type": "client_credentials"}

    result = post(url, headers=headers, data= data)

    json_result = json.loads(result.content)

    token = json_result["access_token"]

    return token

You can use Client Credentials for this, and should use the Authorization Code with PKCE Flow.

Don't forget to the Authorization scopes playlist-modify-public and playlist-modify-private, as mentioned here.
