OAuthlib authentication support for Requests.

Project description

This project provides first-class OAuth library support for Requests.

The OAuth 1 workflow

OAuth 1 can seem overly complicated and it sure has its quirks. Luckily, requests_oauthlib hides most of these and let you focus at the task at hand.

Accessing protected resources using requests_oauthlib is as simple as:

>>> from requests_oauthlib import OAuth1Session
>>> twitter = OAuth1Session('client_key',
>>> url = ''
>>> r = twitter.get(url)

Before accessing resources you will need to obtain a few credentials from your provider (i.e. Twitter) and authorization from the user for whom you wish to retrieve resources for. You can read all about this in the full OAuth 1 workflow guide on RTD.

The OAuth 2 workflow

OAuth 2 is generally simpler than OAuth 1 but comes in more flavours. The most common being the Authorization Code Grant, also known as the WebApplication flow.

Fetching a protected resource after obtaining an access token can be extremely simple. However, before accessing resources you will need to obtain a few credentials from your provider (i.e. Google) and authorization from the user for whom you wish to retrieve resources for. You can read all about this in the full OAuth 2 workflow guide on RTD.


To install requests and requests_oauthlib you can use pip:

$ pip install requests requests_oauthlib
