This app needs your Steam profile visible to the Web API. In the Steam client, open your Profile → Edit Profile → Privacy Settings, then set My profile and Game details to Public. (On the web: steamcommunity.com → Edit Profile → Privacy.) Sign in with Steam above so we know which account to watch.
Roblox badges
Roblox live badges
With the dashboard running on the Roblox platform, new earned badges are detected by polling your
Open Cloud inventory (same API key and player as above). Uses
AUTO_PRINT_ON_UNLOCK and the confirm-print setting below.
Actions
Confirm print uses the status overlay — run
scripts\achievement-printer-status-overlay.bat (dashboard must be running).
Steam must show you In-Game for live unlock detection.
While you play, the dashboard re-checks the Steam API about every 15 seconds.
New unlocks can auto-print when the dashboard is running (AUTO_PRINT_ON_UNLOCK in .env).
Pull achievements calls POST /api/achievements/scan-local — it only creates PNGs; print each sticker from the gallery if you want.
Titles and icons come from Steam after you sign in.
Confirm print uses the status overlay — run
