Integrating a casino API is straightforward when you break it into phases. This tutorial walks through the entire flow from sandbox credentials to first real-money round.

Step 1: Get sandbox access

Sign up with your casino API provider and request sandbox credentials. You will receive an API key, a base URL, and wallet callback documentation. Store the key in a secret manager, never in client code.

Step 2: Map your wallet endpoints

The provider needs four endpoints: debit, credit, rollback, and balance. Each must be idempotent and return JSON with the updated balance. Use transaction IDs to reject duplicates.

Step 3: Launch a game session

Call the provider's /game/launch endpoint with player ID, currency, game ID, and language. The response contains a secure URL. Render it in an iframe or redirect the player.

Step 4: Handle callbacks

Verify the callback signature using the provider's secret
Apply the transaction atomically to the player balance
Return the new balance and a 200 status
Log every callback for reconciliation

Step 5: Build the lobby

Fetch the game catalog, cache provider metadata, and add filters by provider, category, RTP, and volatility. A fast lobby improves player retention.

Step 6: UAT and go-live

Test win/loss flows, insufficient-funds errors, disconnections, and rollback timing. Run a 24-hour soak test in sandbox, then enable production credentials with a small soft-launch audience.
