/**
* Create a configuration object for use in the `loadPaymentData` method.
*
* **Note**: Version 1 of the Google Pay Api is deprecated and will become unsupported in a future version. Until then, version 1 will continue to be used by default, and version 1 schema parameters and overrides will remain functional on existing integrations. However, new integrations and all following examples will be presented in the GooglePay version 2 schema. See [Google Pay's upgrade guide](https://developers.google.com/pay/api/web/guides/resources/update-to-latest-version) to see how to update your integration.

* Optionally, any of the parameters in the [PaymentDataRequest](https://developers.google.com/pay/api/web/reference/object#PaymentDataRequest) parameters can be overridden, but note that it is recommended only to override top level parameters to avoid squashing deeply nested configuration objects. An example can be found below showing how to safely edit these deeply nested objects.
* @example
* var paymentDataRequest = googlePaymentInstance.createPaymentDataRequest({
* merchantInfo: {
* merchantId: 'my-merchant-id-from-google'

* transactionInfo: {
* currencyCode: 'USD',
* totalPriceStatus: 'FINAL',
