See Examples

Required Configuration Options / Environment Variables

Environment Variable	Option Name	Value
TD_AMERITRADE_CLIENT_ID	clientId	YOUR_TD_AMERITRADE_APPLICATION_CLIENT_ID
TD_AMERITRADE_CALLBACK_URL	callbackUrl	http://localhost:3000/tdcallback

Import Module

/** Using ECMAScript Modules */
import { TDAmeritradeAPI } from '@allensarkisyan/schwab-td-ameritrade-api';

/** Using CommonJS */
const { TDAmeritradeAPI } = require('@allensarkisyan/schwab-td-ameritrade-api');

API Client Initialization

/** Create a new instance of TDAmeritradeAPI */
const tdApi = new TDAmeritradeAPI({
  clientId: process.env.TD_AMERITRADE_CLIENT_ID,
  callbackUrl: process.env.TD_AMERITRADE_CALLBACK_URL
});

createTDAmeritradeAPIClient Factory

import { createTDAmeritradeAPIClient } from '@allensarkisyan/schwab-td-ameritrade-api';

const tdApi = createTDAmeritradeAPIClient({
  clientId: process.env.TD_AMERITRADE_CLIENT_ID,
  callbackUrl: process.env.TD_AMERITRADE_CALLBACK_URL
});

Authentication & Authorization

// Step 1: Initiate Authentication request with TD Ameritrade's servers
// Follow the instructions provided by Charles Schwab / TD Ameritrade.

// Step 2: Get Authorization Response code from the query string to your redirect callback URL.
const searchParams = new URLSearchParams(window.location.search);
const authorizationResponseCode = searchParams.get('code');

// Step 3: Authorize the API Client and retrieve an Access Token
const { data: authResponse } = await tdApi.authenticate(authorizationResponseCode);

Setting Access Token Externally

const USER_ACCESS_TOKEN = authResponse?.access_token;
const REFRESH_TOKEN = authResponse?.refresh_token;

// Set User Access Token externally 
tdApi.setUserAccessToken({
  userAccessToken: USER_ACCESS_TOKEN,
  accessTokenExpires: authResponse?.expires_in,
  refreshToken: REFRESH_TOKEN,
  refreshTokenExpires: authResponse?.refresh_token_expires_in,
});
