Process payment

This is a placeholder integration to demonstrate how you might connect to a payment gateway such as MTN Mobile Money or any other provider.

Payment summary

• Unit: Serenity Wellness Salon Suite
• Type: Salon
• Amount due: RWF 920,000

Below is a simplified example of how you might initiate an MTN Mobile Money request using cURL in PHP. Be sure to:

• Store API keys and secrets securely (e.g., environment variables).
• Validate webhook callbacks and handle retries.
• Log transaction statuses for reconciliation.

<?php
// Example MTN MoMo collection request
$apiHost = 'https://sandbox.momodeveloper.mtn.com';
$subscriptionKey = 'REPLACE_WITH_COLLECTION_PRIMARY_KEY'; // Set via environment variable
$accessToken = 'REPLACE_WITH_ACCESS_TOKEN'; // Request via OAuth client credentials

$payload = [
    'amount' => '920,000.00',
    'currency' => 'RWF',
    'externalId' => 'BID-' . time(),
    'payer' => [
        'partyIdType' => 'MSISDN',
        'partyId' => '250700000000', // Customer phone number
    ],
    'payerMessage' => 'Inshuti Residence reservation',
    'payeeNote' => 'Reservation fee',
];

$ch = curl_init($apiHost . '/collection/v1_0/requesttopay');
curl_setopt_array($ch, [
    CURLOPT_HTTPHEADER => [
        'Content-Type: application/json',
        'Authorization: Bearer ' . $accessToken,
        'X-Reference-Id: ' . uuid_create(UUID_TYPE_RANDOM),
        'X-Target-Environment: sandbox', // Switch to "production" in live mode
        'Ocp-Apim-Subscription-Key: ' . $subscriptionKey,
    ],
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => json_encode($payload),
    CURLOPT_RETURNTRANSFER => true,
]);

$response = curl_exec($ch);
if (curl_errno($ch)) {
    // Handle transport error
}
curl_close($ch);
?>

Once the payment API confirms a successful transaction, redirect the client to a receipt page and update your database with the payment reference.
