Overview

OAuth 2.0 authentication with Client Credentials is an authorization flow that allows applications to authenticate directly with the resource server, without the need for user interaction. In this flow, client credentials are used to obtain an access token that can be used to access protected resources.

Implement OAuth 2.0 authentication with Client Credentials

Import the Requests library into your Python file.
Define client information, including the client ID and secret key, as global variables.
```
import requests

CLIENT_ID = 'seu_client_id'
CLIENT_SECRET = 'sua_chave_secreta'
```

Create a function that obtains an access token using client information and the service provider's authorization endpoint.

def get_access_token():
    token_url = 'https://example.com/oauth/token'
    headers = {'Content-Type': 'application/x-www-form-urlencoded'}
    data = {'grant_type': 'client_credentials', 'client_id': CLIENT_ID, 'client_secret': CLIENT_SECRET}
    response = requests.post(token_url, headers=headers, data=data)
    access_token = response.json().get('access_token')
    return access_token

Use the access token to make requests to the protected API.

def get_protected_resource():
    access_token = get_access_token()
    headers = {'Authorization': 'Bearer ' + access_token}
    response = requests.get('https://example.com/api/protected_resource', headers=headers)
    return response.json()
