Authentication Overview

FastTrack Market Data API secures your data transactions with a robust token-based authentication system. Every API request must include specific headers to ensure secure access to our financial datasets.

Required Headers

  • appid: Your unique application identifier, a 36-character string provided in your sign-up confirmation email.

  • token: A temporary 36-character token obtained from the /v1/auth/login endpoint for authenticated API access.

Send both header names exactly as lowercase appid and token. Some v1 endpoints, including the dividends endpoint, reject differently cased header names.

Stay Ahead of Token Expiration

Note on Token Validity Tokens are refreshed daily around 7:20 AM, 6:35 PM, and 8:20 PM EST. Keep your data flow uninterrupted by renewing your tokens with the /auth/login endpoint as needed.

How to Authenticate Your Requests

Authenticating is Simple:

  1. Retrieve Your Token: Use the /v1/auth/login endpoint with your account number, account password, and appid provided during sign-up. The pass value is your account password, not an existing token.
  2. Receive a User Info Object: Read the lowercase token property from the response for subsequent API requests. Other response properties, including accountnumber, appid, and expiration, are also lowercase.

Example: A GET Request with Authentication

GET https://ftl.fasttrack.net/v1/data/sp-da HTTP/1.1
appid: ff867cec-64c8-4d5d-a8d7-3a956d696c5e
token: 0ca5061c-4688-4e4a-ab15-eadd7c2944c7
Host: ftl.fasttrack.net
