My Question or Issue

When trying to access users liked songs via the Spotify API, I can generate an access code, however when trying to use the access code to the

"https://api.spotify.com/v1/me/tracks" endpoint, I just get a 401 error. 

I have attached my code here in case there is a mistake I'm not seeing.

Thanks!

import requests
import base64
import datetime
from urllib.parse import urlencode

client_id = 'CLIENT_ID'
client_secret = 'CLIENT_SECRET'
client_creds = f'{client_id}:{client_secret}'
client_creds_b64 = base64.b64encode(client_creds.encode())

token_url = 'https://accounts.spotify.com/api/token'

token_data = {
    'grant_type':'client_credentials'
}

token_headers = {
    'Authorization':f'Basic {client_creds_b64.decode()}',
    'Content-Type':'application/x-www-form-urlencoded'
}

r = requests.post(token_url, data=token_data, headers=token_headers)

if r.status_code in range(200,299) :
 token_response_data = r.json()
 now = datetime.datetime.now()
 access_token = token_response_data['access_token']
 expires_in = token_response_data['expires_in']
 expires = now + datetime.timedelta(seconds=expires_in)
 did_expire = expires < now

headers = {
    'Authorization':f'Bearer {access_token}'
}

endpoint = 'https://api.spotify.com/v1/me/tracks'
data = urlencode({'market':'UK', 'limit':10, 'offset':5})
lookup_url = f'{endpoint}?{data}'
r = requests.get(lookup_url, headers=headers)

You can't access user data and can't use scopes with client credentials. Use this instead:

token_data = {

    'grant_type':'authorization_code'

}
