Login

The code below shows how to exchange your account number, account password, and appid for a temporary token. The pass query parameter is the account password, not a token.

The temporary token and appid must be passed as headers to all other FT Market Data API requests. Send the header names exactly as lowercase token and appid.

Save the token as a local variable. The request to the /auth/login end point only needs to be called once.

Request Token

Pass your account number, password, and app id as query strings to the "auth/login" end point.

var account = '123456';
var pass = '12345678';
var appid = 'xxxxxx-xxxxx-xxxxxxx';
var token;
var url = 'https://ftl.fasttrack.net/v1/auth/login';

function login(){
  url = url + "?account=" + account + "&pass=" + pass + "&appid=" + appid;
  fetch(url)
  .then(
      function (response) {
        return response.json();
      }
    )
  .then(
    function (userinfo) {
        if (userinfo.err == null) {
          token = userinfo.token;
        }
        else {
          alert(userinfo.err.message);
        }
      }
    )
  .catch(
    function (err) {
      alert(err.message);
      }
    )

The login response uses lowercase property names: accountnumber, pass, token, appid, expiration, and err.

Save Token Locally

Save the retrieved token locally and reuse until expires.

Token Expiration

The token is reset daily at approximately

• 7:20am EST
• 6:35PM EST
• 8:20pm EST

Request new tokens periodically by calling the /auth/login endpoint again.

Any time an expired or invalid token is used, FT Market Data API returns a -5500000 Invalid Token error.
