/**
 * Allows modules to alter defined Alipay API transaction parameters.
 *
 * The Commerce Alipay module defines by default the necessary properties to
 * provide support for the "Direct Pay" Alipay service type.
 * However, Alipay provides other types of services which may require different
 * properties and parameters to be passed when redirecting users for payment.
 * This hook allows other modules to alter these parameters to support other
 * service types, such as "DualFun", by providing additional keyed properties
 * as requested by the Alipay API.
 *
 * A few examples of the possible parameters that could be used along with this
 * hook are described in the implementation example below.
 * For more complete information on the Alipay API, please see:
 * http://club.alipay.com/read-htm-tid-9976972.html
 *
 * @param array $data
 *   An array of keyed properties to be passed to Alipay's payment gateway, in
 *   compliance with its API. Some of the possible keyed properties have been
 *   described in the implementation example below. To disable extensions or
 *   any key of the array, unset it or assign the parameter to null.
 * @param array $settings
 *   An array of the current settings configured for the payment method.
 * @param stdClass $order
 *   If available, the order object for which the payment should be processed.
 *
 * @see commerce_alipay_redirect_form()
