Configure Steam IAP Settings

Enable and configure Steam in LootLocker so it can be used to handle in-app purchases.

Prerequisites

• A Steamworks account

Enable Steam Store

In the LootLocker Web Console, select Settings > In-App Purchases, then 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, 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.

Caution

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.

Once you've filled in the required fields, click the Enable toggle to enable Steam as a purchase provider for your game, then click Save Changes.

Conclusion

You've enabled Steam for in-app purchases and configured the required settings in LootLocker. Next, configure a Catalog Listing for it.
