# Config
This script integrates the **Clinch SDK** into your web app, enabling secure communication between your parent window and the embedded iframe. Below is a brief overview of the **callbacks** and **configuration**.
## **Configuration Object (`config`)**
The `config` object passed to `loadClinch` contains settings that control the behaviour of the Clinch web app.
```typescript
const config = {
operatorId: 'your_operator_id',
gameId: "solitaire",
clinchUrl: "http://embed-sandbox.clinch.gg",
companyName: "your company name",
language: "en",
paymentType: "lightning",
showSats: true,
lightningAddress: "user@company.com",
logging: true,
};
```
* **`operatorId`**: This ID will be provided to you by THNDR
* **`gameId`**: 'solitaire' or 'blocks'
* **`clinchUrl`**: This is the URL for the clinch iframe. This will be provided by THNDR for sandbox (embed-sandbox.clinch.gg) and production (embed.clinch.gg) environments.
* **`companyName`**: This is your company name that will be shown by the users balance of their wallet on your platform.
* **`language`**: Two-letter country code. If language is not supported, defaults to english.
* **`paymentType`**: This must be 'lightning'.
* **`showSats`**: The iframe shows balances in USD. If you want to show a satoshi balance as well, set this to `true`.
* **`lightningAddress`**: The users lightning address that their winnings are sent to
* **`logging`**: When set to `true`, this enables debug mode, allowing additional logging in the console for troubleshooting.
## **Callbacks**
The SDK requires four key callback functions, each responsible for handling specific actions within the Clinch web app.
1. **`getToken`**: Retrieves the authentication token for the user.
2. **`getBalance`**: Returns the current balance for the user.
3. **`onPayInvoice`**: You will receive a bolt11 invoice, which you should pay from your users wallet balance.
## **Example Code Overview**
The code integrates the **Clinch SDK** with the specified configuration and callbacks:
