Basic Usage

Purchase

    use Omnipay\Omnipay;
    use Exception;
    $gateway = Omnipay::create('Esewa_Secure');
    $gateway->setMerchantCode('epay_payment');
    $gateway->setSecretKey('secret_key_provided_by_esewa');
    $gateway->setTestMode(true);
    try {
        $response = $gateway->purchase([
            'amount' => 100,
            'deliveryCharge' => 0,
            'serviceCharge' => 0,
            'taxAmount' => 0,
            'totalAmount' => 100,
            'productCode' => 'ABAC2098',
            'returnUrl' => 'https://merchant.com/payment/1/complete',
            'failedUrl' => 'https://merchant.com/payment/1/failed',
        ])->send();
        if ($response->isRedirect()) {
            $response->redirect();
        }
    } catch (Exception $e) {
        return $e->getMessage();
    }

After successful payment and redirect back to merchant site, you need to verify the payment response.

Verify Payment

    $gateway = Omnipay::create('Esewa_Secure');
    $gateway->setMerchantCode('epay_payment');
    $gateway->setSecretKey('secret_key_provided_by_esewa');
    $gateway->setTestMode(true);
    $payload = json_decode(base64_decode($_GET['data']), true);
    $signature = $gateway->generateSignature(generateSignature($payload));
    if ($signature === $payload['signature']) {
        // Verified
    } else {
        // Unverified
    }

You can also check the status of payment if no any response is received when redirected back to merchant’s site.

Check Status

    $gateway = Omnipay::create('Esewa_Secure');
    $gateway->setMerchantCode('epay_payment');
    $gateway->setSecretKey('secret_key_provided_by_esewa');
    $gateway->setTestMode(true);
    $payload = [
        'totalAmount' => 100,
        'productCode' => 'ABAC2098',
    ];
    $response = $gateway->checkStatus($payload)->send();
    if ($response->isSuccessful()) {
        // Success
    }
