My Question or Issue

I'm trying to request an access token using the /token endpoint with python requests library but keep receiving this error: {'error': 'invalid_grant', 'error_description': 'Invalid authorization code'}. Here's a snippet of my code:

import os import base64 import requests client_id = os.environ.get('CLIENT_ID') client_secret = os.environ.get('CLIENT_SECRET') # taking spotify application variables and base64 encoding credentials = client_id + ':' + client_secret credentials_bytes = credentials.encode('utf-8') credentials_encoded = base64.b64encode(credentials_bytes) authorization = credentials_encoded.decode('utf-8') def token_request(code,redirect_uri): headers = { "Content-Type":"application/x-www-form-urlencoded", "Authorization": f'Basic {authorization}' } body = { "grant_type":"authorization_code", "code":code, "redirect_uri":f'{redirect_uri}' } response = requests.post( 'https://accounts.spotify.com/api/token', data=body, headers=headers ) token = response.json() return token

I'm not sure what issue might to give me this error because I sent the same data through cURL and received an expected response.

Example cURL:

curl -H "Authorization: Basic *<base64 encoded client_id:client_secret>*" -d grant_type=authorization_code -d code=code_from_user_authorization -d redirect_uri=http://my_redirect_uri https://accounts.spotify.com/api/token
