etrade-ts

A TypeScript E-Trade SDK implementation.

Documentation: https://markdoten.github.io/etrade-ts/

E-Trade developer documentation: https://developer.etrade.com/home

IMPORTANT!

The E-Trade documentation shows camel case property names throughout. However, for property names that as assigned to other interfaces, they are title case even though the documentation does not show that. For consistency, properties within responses are converted to camel case, so that it matches the E-Trade documentation.

When making place order requests, a few of the properties need to be title case. The SDK automatically takes care of it.

Authorization

The E-Trade OAuth flow is a multi-step process. Here is the E-Trade OAuth documentation: https://developer.etrade.com/getting-started/developer-guides.

etrade.auth.startOAuth(): Fetxches the OAuth request token and secret, then returns the OAuth URL.

etrade.auth.completeOAuth(verifier: string): Receives the OAuth verifier code, fetches the access token and secret, then set up the session for future use.

Here is an example using Express. Note that the endpoint /etrade/auth/code in this example would be set up in E-Trade as the OAuth callback.

import Etrade from 'etrade-ts';
import express from 'express';
import type {Request, Response} from 'express';

const app = express();
app.use(express.json());

const etrade: Etrade = new Etrade({
  consumerKey: '<consumer key>',
  consumerSecret: '<consumer secret>'
});

app.get('/etrade/auth/start', async (req: Request, res: Response) =>
  res.redirect(await etrade.auth.startOAuth()));

app.get('/etrade/auth/code', async (req: Request, res: Response) => {
  await etrade.auth.completeOAuth(req.query.oauth_verifier.toString());
});

app.listen(8080);

Once the OAuth process is complete, requests can be made using other APIs.

APIs

Each of the APIs (Accounts, Alerts, Market, Order) are available on the Etrade instance.

Most API requests require to be made on a specific account within the E-Trade profile. First you will need to fetch the list of accounts and select which one you want to use.

const {accounts: {account}} = await etrade.accounts.ListAccounts();
console.log(account);

Once you select one of the accounts in the list, the accountIdKey property will need to be passed into most requests:

const {order} = await etrade.order.ListOrders({accountIdKey});
