01

Database Table Setup

Run this SQL command in your phpMyAdmin SQL tab to create a secure payments tracking table.

CREATE TABLE `payments` (
  `id` int(11) PRIMARY KEY AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `order_id` varchar(100) UNIQUE,
  `amount` decimal(10,2),
  `status` enum('pending', 'paid') DEFAULT 'pending',
  `txn_id` varchar(255) DEFAULT NULL,
  `created_at` timestamp DEFAULT CURRENT_TIMESTAMP
);
02

Database Configuration

Create a file named db_config.php and update it with your server credentials.

<?php
// db_config.php - Local Database Connection
$host = "localhost";
$db   = "your_database_name";
$user = "your_database_username";
$pass = "your_database_password";

$conn = new mysqli($host, $user, $pass, $db);
if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); }
?>
03

Payment Initiation

Request a secure payment session from our API. Update YOUR_API_KEY with your brand key.

<?php
include('db_config.php');

if(isset($_POST['pay_now'])) {
    $amount   = $_POST['amount'];
    $order_id = "ORD-" . time();
    
    $api_key  = "YOUR_API_KEY";
    $api_url  = "https://fastpay24.xyz/paymentapi";

    $post_data = [
        'api_key'      => $api_key,
        'amount'       => $amount,
        'order_id'     => $order_id,
        'callback_url' => "https://yourdomain.com/callback.php",
        'redirect_url' => "https://yourdomain.com/success.php?id=" . $order_id
    ];

    $ch = curl_init($api_url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post_data));
    curl_setopt($ch, CURLOPT_REFERER, "https://yourdomain.com");

    $res = json_decode(curl_exec($ch), true);
    if($res['status'] == 'success') {
        $conn->query("INSERT INTO payments (user_id, order_id, amount) VALUES ('1', '$order_id', '$amount')");
        header("Location: " . $res['payment_url']);
    } else { echo "Error: " . $res['message']; }
}
?>
04

Webhook Success Listener

Our server will ping this callback.php file as soon as the payment is confirmed.

<?php
include('db_config.php');
// Anti-Duplicate Protection Ready
$json = file_get_contents('php://input');
$data = json_decode($json, true);

if ($data && $data['status'] == 'paid') {
    $order_id = $data['order_id'];
    $txn_id   = $data['txn_id'];

    $check = $conn->query("SELECT status FROM payments WHERE order_id = '$order_id'");
    $order = $check->fetch_assoc();

    if ($order && $order['status'] !== 'paid') {
        $conn->query("UPDATE payments SET status='paid', txn_id='$txn_id' WHERE order_id='$order_id'");
        // Deliver product/service here...
        http_response_code(200);
        echo "SUCCESS";
    }
}
?>
