Initialize the WebGL SDK

Initialize the SDK using the following function:

CheckoutController.Instance.Init(string CustomerId, string GAID, ICheckoutPurchase callback);

Important: This function must be called during the game's boot process.

If the request is successful, the OnInitialize callback is triggered, indicating that the initialization was completed. If the request fails, the OnInitializeFailed callback is triggered with an error code. Follow the instructions in the WebGL SDK troubleshooting article and try to re-initialize again based on the error.

For more details on the callbacks you need to implement and how to handle them, refer to the Implement the WebGL SDK Callbacks article.
