Warnings

breaking OAuthLib 3.0.0 introduced API-breaking changes, including the removal of 'request' from 'confirm_redirect_uri'.
Fix: Update your code to align with the new API changes introduced in version 3.0.0.
gotcha Ensure that 'requests' is installed when using OAuthLib, as it is commonly used for making HTTP requests in Python applications.
Fix: Install the 'requests' library using 'pip install requests' if it's not already installed.

Install

pip install oauthlib Install OAuthLib

Imports

OAuth1Session
```
from oauthlib.oauth1 import OAuth1Session

Quickstart

A basic example of using OAuthLib with OAuth1Session to make authenticated requests.

import os
from oauthlib.oauth1 import OAuth1Session

# Set up OAuth1Session with your credentials
oauth = OAuth1Session(client_key=os.environ.get('CLIENT_KEY'), client_secret=os.environ.get('CLIENT_SECRET'))

# Make a request to a protected resource
response = oauth.get('https://api.example.com/protected')
print(response.content)
