Casino gaming API for Sao Tome and Principe

Casino gaming API in Sao Tome and Principe: what you actually get

GamingAPI is a casino games aggregator for Sao Tome and Principe. One integration — a single API key, a single secret and one callback URL — connects your brand to 16,000+ games from 150+ certified studios. You never sign a contract per studio, never run a separate wallet per provider and never maintain a second integration when a new studio launches.

The catalogue for Sao Tome and Principe spans slots, live dealer, crash and instant-win, table games, fishing/arcade, lottery, bingo and virtual sports. Operators here get the most traction from Spribe, Pragmatic Play, Evolution, PG Soft and others, with titles such as Aviator, Sweet Bonanza, Crazy Time, Gates of Olympus, Lightning Roulette in constant rotation.

New studios are added to the same catalogue endpoint — no code change on your side.

STN wallet, bets and balance accuracy

The integration is a seamless wallet: your platform stays the single source of truth for player balance. When a player opens a game we call your wallet for the balance, and every bet, win, loss, refund, bonus and jackpot event is delivered to your callback URL signed with HMAC-SHA256 within milliseconds of the round settling.

Every transaction carries a unique serial number and is idempotent at database level, so a duplicate callback can never move the balance twice, and a late win arriving after a session closes is still applied. Balances are auto-reconciled against the provider's own figure, so the number in the game and the number on your Sao Tome and Principe site always match.

Payments and settlement for Sao Tome and Principe operators

Your player cashier stays yours: Bank transfer and crypto deposits are handled on your side in STN. GamingAPI only settles the B2B side — your GGR wallet is topped up with USDT (TRC-20, minimum 15 USDT, roughly Db15) and GGR is deducted automatically per settled round.

Billing is loss-only: commission applies to positive GGR, never to rounds the player wins. Reports in the client panel are shown in STN, and invoices are issued in USD/USDT. Game launch is blocked below roughly Db0.85 so you are never exposed to unbilled play.

Working in STN: rates, rounding and limits

The wallet is native STN (Dobra) — assigned when your account is created and fixed afterwards, so historical reports never shift under you. There is no conversion step inside a round: the stake leaves the player wallet in STN and the win returns in STN, which is why the figure in the game and the figure on your site agree to the last digit. Amounts carry 2 decimals end to end.

Commercial terms are quoted in USD and converted at the reference rate of roughly 1 STN per USD: the one-time setup is $350 (about Db350), the monthly platform fee is Db0, and there is no FX markup, per-call fee or refund fee. Typical stakes run from about Db0.1 to Db500 per round depending on the game, and per-game, per-player and daily limits are configurable from the client panel.

Settlement follows a UTC+2 (daily cut-off 00:00) day. GGR is deducted per settled round in STN, the weekly statement closes on Monday, and the balance is payable in USDT within 48 hours. Because commission only applies to positive GGR, a losing week for the platform costs you nothing.

Going live in Sao Tome and Principe

Sandbox credentials are issued the same day you ask. A typical Sao Tome and Principe operator integrates the launch endpoint and wallet callback in 2–5 days, tests bet/win/refund and duplicate handling in sandbox, then switches to production keys — most brands are live within 5–7 days.

You keep full control of front-end, lobby layout, bonuses, limits and reporting. Licensing, responsible gaming tooling and jurisdiction rules are configurable per brand, and 24/7 Telegram support (@CasinoxApix) covers integration and live incidents.
