API PROBLEM

[wet sleet]

When I try to make payment it works but paypal doesn't receive money and after a while my payment is cancelled, I really don't know how paypal api works, here is the code:

define('access', 'api');
require_once('api.php');

if (!@include_once(rtrim(str_replace('\\', '/', dirname(__DIR__)), '/') . '/includes/webengine.php')) throw new Exception('Could not load WebEngine.');

$cfg = loadConfigurations('donation.paypal');
if (!is_array($cfg)) {
    header("HTTP/1.1 500 Internal Server Error");
    die('Invalid configuration format.');
}

$requiredKeys = ['paypal_enable_sandbox', 'paypal_currency', 'paypal_email', 'paypal_title', 'paypal_conversion_rate'];
foreach ($requiredKeys as $key) {
    if (!isset($cfg[$key])) {
        die("Configuration key missing: $key");
    }
}```

$clientId = $enable_sandbox ? PAYPAL_SANDBOX_CLIENT_ID : PAYPAL_LIVE_CLIENT_ID;
$clientSecret = $enable_sandbox ? PAYPAL_SANDBOX_CLIENT_SECRET : PAYPAL_LIVE_CLIENT_SECRET;

$accessToken = getPayPalAccessToken($clientId, $clientSecret, $enable_sandbox);
if (!$accessToken) {
    throw new Exception('Unable to retrieve PayPal access token');
}

if (isset($_POST['amount']) && is_numeric($_POST['amount']) && floatval($_POST['amount']) > 0) {
    $amount = $_POST['amount'];

    $order_id = md5(time());
    $currency = $cfg['paypal_currency'];
    $user_id = $_SESSION['userid']; // L'ID utente per il sistema

    $approvalUrl = createPayPalOrder($accessToken, $amount, $currency);

    if (!$approvalUrl) {
        throw new Exception('Failed to create PayPal order');
    }

    header('Location: ' . $approvalUrl);
    exit();
} else {
    die('Errore: l\'importo del pagamento non è impostato o non valido.');
}```

    $url = $sandbox ? 'https://api.sandbox.paypal.com/v1/oauth2/token' : 'https://api.paypal.com/v1/oauth2/token';
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_USERPWD, $clientId . ":" . $clientSecret);
    curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

    $response = curl_exec($ch);
    if (curl_errno($ch)) {
        saveLog("cURL error: " . curl_error($ch));
        curl_close($ch);
        return false;
    }

    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    if ($http_code !== 200) {
        saveLog("PayPal token request failed with HTTP code " . $http_code . " Response: " . $response);
        curl_close($ch);
        return false;
    }

    $json = json_decode($response);
    curl_close($ch);
    return $json->access_token ?? false;
}```

    $url = 'https://api.paypal.com/v2/checkout/orders'; 
    $headers = [
        "Content-Type: application/json",
        "Authorization: Bearer " . $accessToken
    ];

    $body = json_encode([
        'intent' => 'CAPTURE',
        'purchase_units' => [
            [
                'amount' => [
                    'currency_code' => $currency,
                    'value' => $amount
                ]
            ]
        ],
        'application_context' => [
            'return_url' => 'https://muonline.test/api/success.php',
            'cancel_url' => 'https://muonline.test/cancel.php' 
        ]
    ]);

    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $body);

    $response = curl_exec($ch);
    if (curl_errno($ch)) {
        curl_close($ch);
        return false;
    }

    $json = json_decode($response);
    curl_close($ch);

    // Trova l'URL di approvazione nella risposta
    if (!empty($json->links)) {
        foreach ($json->links as $link) {
            if ($link->rel === 'approve') {
                return $link->href; // Restituisci l'URL di approvazione
            }
        }
    }

    return false; // Ritorna false se non si trova l'URL
}```

Perhaps toss something about PayPal in the description/topic?
Sounds like you need to debug and that may require you to login to a dashboard with PayPal?

(*The same place they issued the dev keys?)

php is dead just like me sending back response AMF what a disaster

everyone will forget about php sooner or later and you will be stuck like me

in nowadays you have to switch languages to such as nodejs, javascript, python

php is only good for chatgpt
