TD Ameritrade Library for Node.js

Free, open-source Node.js client for the TD Ameritrade Trading Platform.

WARNING This library is still in its early stages of development and thus far from ready for production use.


There are 3 interfaces available:

  • TDAmeritrade - the main API interface.
  • TDAccount - a helper interface to ease the use of account specific functions.
  • TDStreamer - the data streaming interface.

The API client is very close to being complete. All documented API methods have been implemented.

The data streaming interface implements most of what the documentation talks about except Actives, Level 1 Options and Level 2 order book. Documentation also mentions services NEWS_STORY and NEWS_HEADLINE_LIST but does not provide any information.

An attempt to provide typescript definitions is also in progress.


Using npm:

$ npm install @knicola/tdameritrade

Using yarn:

$ yarn add @knicola/tdameritrade


const { TDAmeritrade, TDAccount, TDStreamer } = require('@knicola/tdameritrade')
const config = {
    accessToken: 'access_token',
    apiKey: 'testClientId', // `@AMER.OAUTHAP` suffix is not required
    returnFullResponse: false, // Set to true to return the full axios response (default: false)

// main api interface
const api = new TDAmeritrade(config)
const accounts = await api.getAccounts()
const orders = api.getOrders(accounts[0].accountId).then(orders => {
    // do something with orders ..
    return orders

// account specific interface
const account = new TDAccount(accounts[0].accountId, config)
const orders = account.getOrders()

// data streamer
const userPrincipals = await api.getUserPrincipals([
const streamer = new TDStreamer(userPrincipals)
streamer.on('authenticated', () => streamer.subsChartEquity('SPY'))
streamer.on('chart', data => {
    // do something with chart data ..

Generate an SSL certificate and place it in the root folder before running any tests:

$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout selfsigned.key -out selfsigned.crt -batch

For live tests create an access token:

NPM Scripts

Command Description
npm test Run test suites
npm run lint Run linting rules
npm run coverage Generate coverage report
npm run build Bundle the project for browser use
npm run authorize Run oauth and get an access token for testing (saves the token for later use)
npm run refresh_token Refresh the oauth access token (also saves the new token)
npm run user_principals Get the user principals object used to authenticate to the json streaming service
