要在PHP中使用PayPal API處理退款,請(qǐng)按照以下步驟操作:
composer require paypal/rest-api-sdk-php:*
paypal_config.php
),并將其包含到你的項(xiàng)目中。在此文件中,設(shè)置PayPal API憑據(jù)和其他配置信息:<?php
return [
'client_id' => 'YOUR_CLIENT_ID',
'secret' => 'YOUR_SECRET',
'settings' => [
'mode' => 'sandbox', // 或者 'live'
'http.ConnectionTimeOut' => 30,
'log.LogEnabled' => true,
'log.FileName' => 'PayPal.log',
'log.LogLevel' => 'FINE'
]
];
refund.php
),并引入PayPal SDK和配置文件:<?php
require __DIR__ . '/vendor/autoload.php';
$config = require __DIR__ . '/paypal_config.php';
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;
$apiContext = new ApiContext(
new OAuthTokenCredential($config['client_id'], $config['secret'])
);
$apiContext->setConfig($config['settings']);
use PayPal\Api\Amount;
use PayPal\Api\Refund;
use PayPal\Api\RefundRequest;
use PayPal\Api\Sale;
$saleId = 'YOUR_SALE_ID'; // 從之前的支付中獲取
$amountToRefund = new Amount();
$amountToRefund->setCurrency('USD')
->setTotal('10.00'); // 退款金額
$refundRequest = new RefundRequest();
$refundRequest->setAmount($amountToRefund);
$sale = new Sale();
$sale->setId($saleId);
try {
$refundedSale = $sale->refund($refundRequest, $apiContext);
echo "Refunded Successfully\n";
echo "Refund ID: " . $refundedSale->getId() . "\n";
echo "Refund Amount: " . $refundedSale->getAmount()->getTotal() . "\n";
} catch (Exception $ex) {
echo "Error: " . $ex->getMessage() . "\n";
}
refund.php
文件以執(zhí)行退款操作。注意:請(qǐng)確保將YOUR_CLIENT_ID
、YOUR_SECRET
和YOUR_SALE_ID
替換為實(shí)際的PayPal API憑據(jù)和銷售ID。
這樣,你就可以使用PayPal PHP SDK處理退款了。根據(jù)需要調(diào)整代碼以適應(yīng)你的應(yīng)用程序。
