A generic, spec-compliant, thorough implementation of the OAuth request-signing logic.

OAuth often seems complicated and difficult-to-implement. There are several prominent libraries for signing OAuth requests, but they all suffer from one or both of the following:

  1. They predate the OAuth 1.0 spec, AKA RFC 5849.
  2. They assume the usage of a specific HTTP request library.

OAuthLib is a generic utility which implements the logic of OAuth without assuming a specific HTTP request object. Use it to graft OAuth support onto your favorite HTTP library. If you're a maintainer of such a library, write a thin veneer on top of OAuthLib and get OAuth support for very little effort.


Full documentation is available on Read the Docs. All contributions are very welcome! The documentation is still quite sparse, please open an issue for what you'd like to know, or discuss it in our G+ community, or even better, send a pull request!

Interested in making OAuth requests?

Then you might be more interested in using requests which has OAuthLib powered OAuth support provided by the requests-oauthlib library.

Using OAuthLib? Please get in touch!

Patching OAuth support onto an http request framework? Creating an OAuth provider extension for a web framework? Simply using OAuthLib to Get Things Done or to learn?

No matter which we'd love to hear from you in our G+ community or if you have anything in particular you would like to have, change or comment on don't hesitate for a second to send a pull request or open an issue. We might be quite busy and therefore slow to reply but we love feedback!

Chances are you have run into something annoying that you wish there was documentation for, if you wish to gain eternal fame and glory, and a drink if we have the pleasure to run into eachother, please send a docs pull request =)
