php-omnipayHow can I use PHP Omnipay to process a billing transaction?
PHP Omnipay is a library for processing payment transactions. It supports a wide range of popular payment gateways and provides an easy way to integrate with them. To process a billing transaction with PHP Omnipay:
- Install the library using Composer:
composer require omnipay/omnipay
- Initialize the gateway object with your credentials:
$gateway = Omnipay::create('PayPal_Express');
$gateway->setUsername('your_username');
$gateway->setPassword('your_password');
$gateway->setSignature('your_signature');
- Set the transaction parameters:
$params = [
'amount' => 10.00,
'currency' => 'USD',
'returnUrl' => 'https://www.example.com/return',
'cancelUrl' => 'https://www.example.com/cancel',
];
- Send the transaction request:
$response = $gateway->purchase($params)->send();
- Check the response:
if ($response->isSuccessful()) {
// Payment was successful
} elseif ($response->isRedirect()) {
// Redirect to offsite payment gateway
$response->redirect();
} else {
// Payment failed
echo $response->getMessage();
}
- Complete the transaction:
$purchaseResponse = $gateway->completePurchase($params)->send();
if ($purchaseResponse->isSuccessful()) {
// Payment was successful
} else {
// Payment failed
echo $purchaseResponse->getMessage();
}
- Finally, check the transaction status:
$statusResponse = $gateway->fetchTransaction($params)->send();
if ($statusResponse->isSuccessful()) {
// Payment status is successful
} else {
// Payment status failed
echo $statusResponse->getMessage();
}
