# Interface: GooglePayPaymentInitializeOptions

A set of options that are required to initialize the GooglePay payment method

If the customer chooses to pay with GooglePay, they will be asked to
enter their payment details via a modal. You can hook into events emitted by
the modal by providing the callbacks listed below.

```html
<!-- This is where the GooglePay button will be inserted -->
<div id="wallet-button"></div>
```

```js
service.initializePayment({
    // Using GooglePay provided by Braintree as an example
    methodId: 'googlepaybraintree',
    googlepaybraintree: {
        walletButton: 'wallet-button'
    },
});
```

Additional event callbacks can be registered.

```js
service.initializePayment({
    methodId: 'googlepaybraintree',
    googlepaybraintree: {
        walletButton: 'wallet-button',
        onError(error) {
            console.log(error);
        },
        onPaymentSelect() {
            console.log('Selected');
        },
    },
});
```
