TD Ameritrade API gem for Ruby

This is a gem for connecting to the OAuth/JSON-based TD Ameritrade Developers API released in 2018. Go to https://developer.tdameritrade.com/ for the official documentation and to create your OAuth application.

For a gem that allows you to connect to the older version of the TDAmeritrade API, go to https://github.com/wakproductions/tdameritrade_api

Installation

In your Gemfile

gem 'tdameritrade-api-ruby', git: 'https://github.com/wakproductions/tdameritrade-api-ruby.git'

Authenticating

Currently this gem is designed for private app authorization. Read this guide for a general overview of signing in your private app: https://developer.tdameritrade.com/content/simple-auth-local-apps

The TD Ameritrade API now uses OAuth for authentication. For an introduction to the OAuth flow, I recommend reading this tutorial.

I plan on writing more detailed instructions in the file /doc/authentication.md

See my video Stonks on Rails Episode #2 - Connecting to TD Ameritrade via OAuth for a more detailed walkthrough of the OAuth authentication process.

Basic Usage

client = TDAmeritrade::Client.new(
  client_id: 'MYCLIENTID@AMER.OAUTHAP', 
  redirect_uri: 'http://my-redirect-url', 
  refresh_token: 'b6w31RJvP/Cz3MVghpx8S5dzeYVcHygEQHKWYQuI98NGpsMb1j...'
)

client.get_instrument_fundamentals('TWTR')
#=> {"TWTR"=>
      {"fundamental"=>
        {"symbol"=>"TWTR",
