PHP亚马逊API开发：如何实现退款和退货功能

<?php
require 'vendor/autoload.php'; // 加载亚马逊API的PHP SDK

use AmazonMWSSubscriptionsServiceMarketplaceWebServiceSellers_Client;
use AmazonMWSClient; 

// 配置API参数
$awsAccessKeyId = 'YOUR_AWS_ACCESS_KEY_ID';
$awsSecretAccessKey = 'YOUR_AWS_SECRET_ACCESS_KEY';
$sellerId = 'YOUR_SELLER_ID';
$marketplaceId = 'YOUR_MARKETPLACE_ID';
$mwsAuthToken = 'YOUR_MWS_AUTH_TOKEN';

// 初始化亚马逊API客户端
$client = new MarketplaceWebServiceSellers_Client($awsAccessKeyId, $awsSecretAccessKey, array(
    'ServiceURL' => 'https://mws.amazonservices.com',
    'ProxyHost' => null,
    'ProxyPort' => -1,
    'MaxErrorRetry' => 3,
));

// 构建请求参数
$request = new MarketplaceWebServiceSellersModelGetServiceStatusRequest();
$request->setSellerId($sellerId);
$request->setMWSAuthToken($mwsAuthToken);

// 发送请求并获取响应
$response = $client->getServiceStatus($request);

// 处理响应数据
if($response->isSetGetServiceStatusResult()){
    $getServiceStatusResult = $response->getGetServiceStatusResult();
    if($getServiceStatusResult->isSetStatus()){
        echo 'Service status: ' . $getServiceStatusResult->getStatus();
    }
}
