Setup

Connect the data sources

CS2Mate pulls live data from Steam Web API and FACEIT Data API. Steam is required; FACEIT is optional but unlocks per-match history, ELO trends, and windowed stats. Setup takes about 5 minutes total.

FACEIT_API_KEY — how to get one

~3 min
  1. 1

    Sign in to FACEIT developers

    Go to developers.faceit.com and sign in with your FACEIT account. If you don't have one yet, sign up first — it's free.
  2. 2

    Create a new app

    Hit + New app on the dashboard. Name it anything (e.g. cs2mate), pick the Server-side type, accept the terms. No callback URL needed for the Data API.
  3. 3

    Copy the server-side key

    Once the app is created, FACEIT shows a Server-side API key. Copy it — it starts with eyJ… (a JWT).
  4. 4

    Add it to Vercel

    Open your Vercel dashboard, pick the cs2mate project → Settings → Environment Variables. Add a new variable:
    FACEIT_API_KEYProduction · Preview · Development
    paste the key here
    Then Redeploy — the production deployment needs to pick up the new env. Either trigger a manual redeploy from the dashboard or push any commit.
  5. 5

    Verify

    Refresh this page. The card above flips to green and your /dashboard starts pulling FACEIT data. If you see “FACEIT player not found”, your Steam account isn't linked to a FACEIT account yet — sign in on faceit.com with Steam once and try again.

  1. 1

    Open Steam dev page

    Go to steamcommunity.com/dev/apikey while signed in to Steam.
  2. 2

    Register a key

    Type a domain name (your deployed URL, e.g. cs2mate.com — or localhost for dev). Accept the terms. The key appears immediately.
  3. 3

    Add to Vercel

    Same as above — add STEAM_API_KEY to Environment Variables, then redeploy.
AUTH_SECRET — sign-in cookiesexpand

Used to HMAC-sign the session cookie + user prefs cookie so they can't be tampered with. Any long random string works — generate one with:

openssl rand -base64 48

Then add AUTH_SECRETto Vercel env vars, same path as the other two. Don't rotate it without expecting every signed-in user to be logged out.

Display name, currency, goals, languages — all in /settings.

Open the dashboard

Once the keys are in, your data lands here within seconds.
