Notell Slots API
Integrate a catalog of 446 slot games into your casino: launch a game for a player with one server call, keep the balance in your own wallet, grant free spins, schedule target outcomes, tune limits and RTP — and manage everything from the admin panel.
The API base URL is https://notell-api.com. All calls are server-to-server JSON over HTTPS.
