In this simple article i will have to take you through the Fluttervave document to easily implement the system into your PHP project.

So Let Get Started!

Throughout this process we create just 3 files in our project named: index, pay and process

Index.php

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <title>Rave payment Gateway</title>
        <meta name="description" content="">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <link rel="stylesheet" href="">
    </head>
    <body>
        <form action="pay.php" method="POST">

        <label>Email</label>
        <input type="email" name="email">
        <br>
        <label>Amount</label>
        <input type="number" name="amount">
        <br>
        <input type="submit" name="pay" vlaue="Send Payment">

        </form>
    </body>
</html>

pay.php

<?php 
if(isset($_POST['pay']))
{
    $email = $_POST['email'];
    $amount = $_POST['amount'];

    //* Prepare our rave request
    $request = [
        'tx_ref' => time(),
        'amount' => $amount,
        'currency' => 'NGN',
        'payment_options' => 'card',
        'redirect_url' => 'http://localhost/yt/rave/process.php',
        'customer' => [
            'email' => $email,
            'name' => 'Zubdev'
        ],
        'meta' => [
            'price' => $amount
        ],
        'customizations' => [
            'title' => 'Paying for a sample product',
            'description' => 'sample'
        ]
    ];

    //* Ca;; f;iterwave emdpoint
    $curl = curl_init();

    curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://api.flutterwave.com/v3/payments',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POSTFIELDS => json_encode($request),
    CURLOPT_HTTPHEADER => array(
        'Authorization: Bearer FLWSECK_TEST-eee25be1b44ef9a132a872075b3a0910-X',
        'Content-Type: application/json'
    ),
    ));

    $response = curl_exec($curl);

    curl_close($curl);
    
    $res = json_decode($response);
    if($res->status == 'success')
    {
        $link = $res->data->link;
        header('Location: '.$link);
    }
    else
    {
        echo 'We can not process your payment';
    }
}

?>

process.php

<?php 
    if(isset($_GET['status']))
    {
        //* check payment status
        if($_GET['status'] == 'cancelled')
        {
            // echo 'YOu cancel the payment';
            header('Location: index.php');
        }
        elseif($_GET['status'] == 'successful')
        {
            $txid = $_GET['transaction_id'];

            $curl = curl_init();
            curl_setopt_array($curl, array(
                CURLOPT_URL => "https://api.flutterwave.com/v3/transactions/{$txid}/verify",
                CURLOPT_RETURNTRANSFER => true,
                CURLOPT_ENCODING => "",
                CURLOPT_MAXREDIRS => 10,

              $res = json_decode($response);
              if($res->status)
              {
                $amountPaid = $res->data->charged_amount;
                $amountToPay = $res->data->meta->price;
                if($amountPaid >= $amountToPay)
                {
                    echo 'Payment successful';

                    //* Continue to give item to the user
                }
                else
                {
                    echo 'Fraud transactio detected';
                }
              }
              else
              {

Hi thanks so much for this , but is there a way to get the transaction details ghrou GET and also, am using this gateway for an E-commerce website where order_id is necessary, so is there a way to send order_id as a GET request through the pay.php and also update database with it in the process.php ?
