Gem Version

Evernote SDK for Ruby

Evernote API version 1.25


This SDK contains wrapper code used to call the Evernote Cloud API from Ruby.

The SDK also contains two samples. The code in sample/client demonstrates the basic use of the SDK for single-user scripts. The code in sample/oauth demonstrates the basic use of the SDK for web applications that authenticate using OAuth.

Install the gem

gem install evernote-thrift


In order to use the code in this SDK, you need to obtain an API key from You'll also find full API documentation on that page.

In order to run the sample code, you need a user account on the sandbox service where you will do your development. Sign up for an account at

In order to run the client client sample code, you need a developer token. Get one at

Getting Started - Client

The code in sample/client/EDAMTest.rb demonstrates the basics of using the Evernote API, using developer tokens to simplify the authentication process while you're learning.

  1. Open sample/client/EDAMTest.rb
  2. Scroll down and fill in your Evernote developer token.
  3. On the command line, run the following command to execute the script:

    ruby EDAMTest.rb

Getting Started - OAuth

Web applications must use OAuth to authenticate to the Evernote service. The code in sample/oauth contains 2 simple web apps that demonstrate the OAuth authentication process. The applications use the Sinatra framework. You don't need to use Sinatra for your application, but you'll need it to run the sample code. The applications also use the OAuth RubyGem to provide the underlying OAuth functionality.

There are two pages in the sample. evernote_oauth.rb demonstrates each step of the OAuth process in detail. This is useful for developers, but not what an end user would see. evernote_oauth_simple demonstrates the simplified process, which is similar to what you would implement in your production app.

  1. Install Sinatra: gem install sinatra
  2. Install OAuth: gem install oauth
  3. Open the file sample/oauth/evernote_config.rb
  4. Fill in your Evernote API consumer key and secret.
  5. On the command line, run the following command to start the datailed sample app:

    ruby -rubygems evernote_oauth.rb

  6. Open the sample app in your browser: http://localhost:4567

  7. Repeat steps 5 and 6 with the file evernote_oauth_simple.rb to run the simple sample app.

Getting Started - evernote_oauth gem

We also provide a high level wrapper for the Thrift API client. You can install it with: gem install evernote_oauth
