SANDBOX FAQ

Questions developers ask

Browse the docs
Is the sandbox free?

Yes. Sign up for a free sandbox API key. No top-up, crypto payment or production balance is needed to test.

Do I need crypto to test?

No. The sandbox is free and uses a simulated balance. Crypto is used only to fund a live prepaid balance.

Which games can I test?

You can launch demo games in the sandbox. Full field reference is included with your sandbox key.

How do I move from sandbox to live?

Create your live account and top up from €500 in crypto on casino-games-aggregation.com/register, then use your production API key. Live accounts, top-ups and production API keys are handled there.

Do players need crypto?

No. Operators fund the live prepaid balance in crypto; the API supports 150 fiat currencies for players.

How are wallet callbacks signed?

The X-Signature header contains HMAC-SHA256 of the raw request body using your webhook secret. Verify the signature on your server before processing a callback.

Is this a gambling site?

No. casino201 is a B2B developer and operator resource for a casino game aggregation API, not a gambling site.

Test before you top up.
