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 (e.g. 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 (e.g. 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


v2.0.0 (22 March 2024)

Full set of changes are in [github](

Additions & changes:

  • OAuth2Session now correctly uses the self.verify value if verify is not overridden in fetch_token and refresh_token. Fixes #404.

  • OAuth2Session constructor now uses its client.scope when a client is provided and scope is not overridden. Fixes #408

  • Add refresh_token_request and access_token_request compliance hooks

  • Add PKCE support and Auth0 example

  • Add support for Python 3.8-3.12

  • Remove support of Python 2.x, <3.7

  • Migrated to Github Action

  • Updated dependencies

  • Cleanup some docs and examples

v1.4.0 (27 Feb 2024)

  • Version 2.0.0 published initially as 1.4.0, it was yanked eventually.

v1.3.1 (21 January 2022)

  • Add initial support for OAuth Mutual TLS (draft-ietf-oauth-mtls)

  • Removed outdated LinkedIn Compliance Fixes

  • Add eBay compliance fix

  • Add Spotify OAuth 2 Tutorial

  • Add support for python 3.8, 3.9

  • Fixed LinkedIn Compliance Fixes

  • Fixed ReadTheDocs Documentation and sphinx errors

  • Moved pipeline to GitHub Actions

v1.3.0 (6 November 2019)

  • Instagram compliance fix

  • Added force_querystring argument to fetch_token() method on OAuth2Session

v1.2.0 (14 January 2019)

  • This project now depends on OAuthlib 3.0.0 and above. It does not support versions of OAuthlib before 3.0.0.

  • Updated oauth2 tests to use ‘sess’ for an OAuth2Session instance instead of auth because OAuth2Session objects and methods acceept an auth paramether which is typically an instance of requests.auth.HTTPBasicAuth

  • OAuth2Session.fetch_token previously tried to guess how and where to provide “client” and “user” credentials incorrectly. This was incompatible with some OAuth servers and incompatible with breaking changes in oauthlib that seek to correctly provide the client_id. The older implementation also did not raise the correct exceptions when username and password are not present on Legacy clients.

  • Avoid automatic netrc authentication for OAuth2Session.

v1.1.0 (9 January 2019)

  • Adjusted version specifier for oauthlib dependency: this project is not yet compatible with oauthlib 3.0.0.

  • Dropped dependency on nose.

  • Minor changes to clean up the code and make it more readable/maintainable.

v1.0.0 (4 June 2018)

  • Removed support for Python 2.6 and Python 3.3. This project now supports Python 2.7, and Python 3.4 and above.

  • Added several examples to the documentation.

  • Added plentymarkets compliance fix.

  • Added a token property to OAuth1Session, to match the corresponding token property on OAuth2Session.

v0.8.0 (14 February 2017)

  • Added Fitbit compliance fix.

  • Fixed an issue where newlines in the response body for the access token request would cause errors when trying to extract the token.

  • Fixed an issue introduced in v0.7.0 where users passing auth to several methods would encounter conflicts with the client_id and client_secret-derived auth. The user-supplied auth argument is now used in preference to those options.

v0.7.0 (22 September 2016)

  • Allowed OAuth2Session.request to take the client_id and client_secret parameters for the purposes of automatic token refresh, which may need them.

v0.6.2 (12 July 2016)

  • Use client_id and client_secret for the Authorization header if provided.

  • Allow explicit bypass of the Authorization header by setting auth=False.

  • Pass through the proxies kwarg when refreshing tokens.

  • Miscellaneous cleanups.

v0.6.1 (19 February 2016)

  • Fixed a bug when sending authorization in headers with no username and password present.

  • Make sure we clear the session token before obtaining a new one.

  • Some improvements to the Slack compliance fix.

  • Avoid timing problems around token refresh.

  • Allow passing arbitrary arguments to requests when calling fetch_request_token and fetch_access_token.

v0.6.0 (14 December 2015)

  • Add compliance fix for Slack.

  • Add compliance fix for Mailchimp.

  • TokenRequestDenied exceptions now carry the entire response, not just the status code.

  • Pass through keyword arguments when refreshing tokens automatically.

  • Send authorization in headers, not just body, to maximize compatibility.

  • More getters/setters available for OAuth2 session client values.

  • Allow sending custom headers when refreshing tokens, and set some defaults.

v0.5.0 (4 May 2015)

  • Fix TypeError being raised instead of TokenMissing error.

  • Raise requests exceptions on 4XX and 5XX responses in the OAuth2 flow.

  • Avoid AttributeError when initializing the OAuth2Session class without complete client information.

v0.4.2 (16 October 2014)

  • New authorized property on OAuth1Session and OAuth2Session, which allows you to easily determine if the session is already authorized with OAuth tokens or not.

  • New TokenMissing and VerifierMissing exception classes for OAuth1Session: this will make it easier to catch and identify these exceptions.

v0.4.1 (6 June 2014)

  • New install target [rsa] for people using OAuth1 RSA-SHA1 signature method.

  • Fixed bug in OAuth2 where supplied state param was not used in auth url.

  • OAuth2 HTTPS checking can be disabled by setting environment variable OAUTHLIB_INSECURE_TRANSPORT.

  • OAuth1 now re-authorize upon redirects.

  • OAuth1 token fetching now raise a detailed error message when the response body is incorrectly encoded or the request was denied.

  • Added support for custom OAuth1 clients.

  • OAuth2 compliance fix for Sina Weibo.

  • Multiple fixes to facebook compliance fix.

  • Compliance fixes now re-encode body properly as bytes in Python 3.
