要在PHP中使用PayPal API處理退款,請(qǐng)按照以下步驟操作:

  1. 首先,確保已經(jīng)安裝了PayPal PHP SDK。如果尚未安裝,可以通過Composer進(jìn)行安裝:
composer require paypal/rest-api-sdk-php:*
  1. 創(chuàng)建一個(gè)配置文件(例如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'
    ]
];
  1. 現(xiàn)在,創(chuàng)建一個(gè)新的PHP文件(例如refund.php),并引入PayPal SDK和配置文件:
<?php
require __DIR__ . '/vendor/autoload.php';
$config = require __DIR__ . '/paypal_config.php';
  1. 使用配置信息初始化PayPal API:
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;

$apiContext = new ApiContext(
    new OAuthTokenCredential($config['client_id'], $config['secret'])
);
$apiContext->setConfig($config['settings']);
  1. 創(chuàng)建一個(gè)退款請(qǐng)求:
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);
  1. 發(fā)送退款請(qǐng)求并處理響應(yīng):
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";
}
  1. 運(yùn)行refund.php文件以執(zhí)行退款操作。

注意:請(qǐng)確保將YOUR_CLIENT_IDYOUR_SECRETYOUR_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。
