   * @function create
   * @param {object} options Creation options:
   * @param {Client} [options.client] A {@link Client} instance.
   * @param {string} [options.authorization] A tokenizationKey or clientToken. Can be used in place of `options.client`.
   * @param {Number} [options.googlePayVersion] The version of the Google Pay API to use. Value of 2 is required to accept parameters documented [by Google](https://developers.google.com/pay/api/web/reference/object). Omit this parameter to use the deprecated Google Pay Version 1.
   * @param {String} [options.googleMerchantId] A Google merchant identifier issued after your website is approved by Google. Required when PaymentsClient is initialized with an environment property of PRODUCTION, but may be omitted in TEST environment.
   * @param {callback} [callback] The second argument, `data`, is the {@link GooglePayment} instance. If no callback is provided, `create` returns a promise that resolves with the {@link GooglePayment} instance.
