Step 3: Install the SDK

@hizi.io/engine-sdk is the typed client between your frontend and the running engine. It is on the public npm registry. You need no registry setup.

npm install --save-exact @hizi.io/[email protected]

What to do

1. Read token and login from your page's query string (see Step 2).
2. Connect once through the SDK getting-started guide. Preserve metadata needed by the operator and reality checks.
3. Apply gameSettings in your UI. This includes stake limits, autoplay, gamble, and other operator platform rules. The engine validates financial requests. Your frontend implements the controls and disclosures.
4. Call loadConfig({ backendURL, token }) to get the game's configuration. This includes the available stakes, RTP (return to player), buy-feature options, and any per-game tables your client needs to render.
5. Check the success boolean on every response before you read result.

TIP

Keep the long-life token and backendURL for the rest of the session. Every later call needs them. The launch token can be single-use, and login() consumes it. Call login() once. Do not add a second connect path beside it.
