An OAuth 1.0A library written in PHP by @themattharris, specifically for use with the Twitter API.

Disclaimer: This project is a work in progress and may contain bugs.


  • Support OAuth 1.0A
  • Use Authorisation headers instead of query string or POST parameters
  • Allow uploading of images
  • Provide enough information to assist with debugging


The library has been tested with PHP 5.3+ and relies on CURL and hash_hmac. The vast majority of hosting providers include these libraries and run with PHP 5.1+.

The code makes use of hash_hmac, which was introduced in PHP 5.1.2. If you version of PHP is lower than this you should ask your hosting provider for an update.


This will be built out later but for the moment review the examples for ways the library can be used. Each example contains instructions on how to use it
