liqpay
Для приема платежей через liqpay нужно зарегистрироваться и получить merchant_id и merchant_signature, которые далее будут использованы для подписи запросов и проверки ответов.
Собственно пример отправки на liqpay:
<?php
require_once 'config.php';
$xml = '<request>
<version>1.2</version>
<merchant_id>' . MERCHANT_ID . '</merchant_id>
<result_url>http://example.com/process.php</result_url>
<server_url>http://example.com/process.php</server_url>
<order_id>' . time() . '</order_id>
<amount>0.03</amount>
<currency>UAH</currency>
<description>test</description>
<default_phone></default_phone>
<pay_way></pay_way>
<goods_id>1234</goods_id>
</request>';
$sign = base64_encode(sha1(MERCHANT_SIGNATURE . $xml . MERCHANT_SIGNATURE, true));
$xml_encoded = base64_encode($xml);

result_url - страница куда будет перенаправлен пользователь после проплаты в liqpay.
server_url - url который будет дергать liqpay после проплаты.
Их можно указать одинаковыми - соотв. там же и проверяем и пишем в базу и показываем пользователю сообщение о том что все прошло успешно.
Обработка ответа liqpay:
<?php
require_once 'config.php';
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$xml_decoded = base64_decode($_POST['operation_xml']);
$xml = new SimpleXMLElement($xml_decoded);
$signature = base64_encode(sha1(MERCHANT_SIGNATURE . $xml_decoded . MERCHANT_SIGNATURE, true));
if ($_POST['signature'] == $signature) {
// success, failure, wait_secure
if ($xml->status == 'success') {
echo '<h1>Success</h1>';
}
} else {
echo '<h1>Wrong Signature</h1>';
}
} else {
echo '<h1>Wrong Method</h1>';
}Вот дамп того что происходит на этой страничке:

3PT3CmSld9MLD8qlmZtUZg8V28=И еще один пример, проверки проплаты по id транзакции или заказа:
<?php
require_once 'config.php';
$request_xml = new SimpleXMLElement('<request></request>');
$request_xml->addChild('version', 1.2);
$request_xml->addChild('action', 'view_transaction');
$request_xml->addChild('merchant_id', MERCHANT_ID);
$request_xml->addChild('transaction_id' /*, 33096903*/);
$request_xml->addChild('transaction_order_id', 1388267638);
$request_xml = $request_xml->asXML();
$operation_xml = base64_encode($request_xml);
$signature = base64_encode(sha1(MERCHANT_SIGNATURE . $request_xml . MERCHANT_SIGNATURE, true));
$request_xml = new SimpleXMLElement('<request></request>');
$operation_envelope = $request_xml->addChild('liqpay')->addChild('operation_envelope');
$operation_envelope->addChild('operation_xml', $operation_xml);
$operation_envelope->addChild('signature', $signature);
$ch = curl_init('https://www.liqpay.com/?do=api_xml');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: text/xml'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request_xml->asXML());
$result = curl_exec($ch);
curl_close($ch);
$response_xml = new SimpleXMLElement($result);
$xml_decoded = base64_decode($response_xml->liqpay->operation_envelope->operation_xml);
$xml = new SimpleXMLElement($xml_decoded);
$signature = base64_encode(sha1(MERCHANT_SIGNATURE . $xml_decoded . MERCHANT_SIGNATURE, true));
if ($response_xml->liqpay->operation_envelope->signature == $signature) {
echo '<pre>' . print_r($xml, true) . '</pre>';
}Ответ будет приблизительно таким:
SimpleXMLElement Object

[action] => view_transaction
[merchant_id] => i3000545000
[status] => success
[transaction] => SimpleXMLElement Object
