Registering your store

Call the RegisterStore method supplying a name for your store and your implementation, which must implement the IStore interface.

public override void Configure() {
    RegisterStore(“GooglePlay”, InstantiateMyStore());
}

private void InstantiateMyStore() {
    if (Application.platform == RuntimePlatform.Android) {
        return new MyAlternativeGooglePlayImplementation ();
    }
    return null;
}

The store name must match the name developers use when defining products for your store so Unity IAPAbbreviation of Unity In App Purchase
See in Glossary
uses the correct product identifiers when addressing your store.
