Select Steam Store from the list of available providers.

### Configure Steam Store Settings

Fill in the following fields:

* **App ID:** The unique identifier for your game on Steam. This must match the App ID assigned to your application in the Steamworks dashboard.
* **Publisher Key:** Your Steam Web API publisher key. This key is used to authenticate server-to-server requests for validating purchases and retrieving entitlement data.
* **Sandboxed:** Enables sandbox (test) mode for Steam purchases. Use this during development to simulate transactions without affecting live user data.

{% hint style="warning" %}
Your Publisher Key can be generated in the Steamworks dashboard under API access. Keep this key secure and never expose it in client-side code. Sandbox mode should only be used for testing. Disable it before going live to ensure real purchases are processed correctly.
{% endhint %}

Once all required fields have been filled in, click the Enable toggle to enable Steam as a purchase provider for your game.

Click Save Changes to save your configuration.

### Conclusion

In this guide, we enabled Steam for in-app purchases and configured the required settings in LootLocker. Next, you can create purchasable catalog listings that can be purchasesd in-game.
