I am trying to build a payment plugin for Joomdonation Documents Seller. I can send an order to a Bank and pay, but after that I am having a problem.

When an order is created and sent, it has status: in_progress, after the payment status changes to success, I try to change the record in database with if ($status == success) but this fails.

Here are both files:

Start payment

session_start();

defined('_JEXEC') or die;

class os_bog extends DSFPayment
{
    public function __construct($params, $config = [])
    {
        parent::__construct($params, $config);
    }

    public function processPayment($row, $data)
    {
        $curl = curl_init();
        curl_setopt_array($curl, array(
            CURLOPT_URL => 'https://ipay.ge/opay/api/v1/oauth2/token',
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => '',
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 0,
            CURLOPT_FOLLOWLOCATION => true,

            CURLOPT_HTTPHEADER =>array('Content-Type: application/x-www-form-urlencoded','Authorization: Basic '. base64_encode($client_id.':'.$secret_key)),
        ));
    
        $response = curl_exec($curl);
        curl_close($curl);
        $response = json_decode($response, true);
        $token = $response ['access_token'];
        
        $curl = curl_init();
        curl_setopt_array($curl, array(

    {

        {

    }

    protected function validate()
    {
        $this->notificationData = $_REQUEST;
        return true;
    }   
}

Check status of payment

session_start();
    
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://ipay.ge/opay/api/v1/oauth2/token',
    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 => 'grant_type=client_credentials',
    CURLOPT_HTTPHEADER =>array('Content-Type: application/x-www-form-urlencoded','Authorization: Basic '. base64_encode($client_id.':'.$secret_key)),
));
$response = curl_exec($curl);

curl_close($curl);
$response = json_decode($response, true);
$token = $response ['access_token'];
$order_data = ($_SESSION['order_data']);
$order_id = $order_data['order_id'];
$payment_hash = $order_data['payment_hash'];
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://ipay.ge/opay/api/v1/checkout/payment/'.$order_id,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => 'GET',
    CURLOPT_HTTPHEADER => array(
    'Content-Type:  application/json',
    'Authorization: Bearer' . $token  ),
));

$response = curl_exec($curl);
curl_close($curl);
$response = json_decode($response, true);
$status = $response ['status'];

p.s. I can not check payment inside the plugin(first code), callback url is predefined by the Bank and I was not able to put code inside public function verifyPayment()

Could someone help?

    This might not be resolving advice, but I am noticing that you are manually crafting the json string in the CURLOPT_POSTFIELDS value. You should never craft your own json string manually. You should build an array, then for CURLOPT_POSTFIELDS you can either pass in a json_encode() or http_build_query() string.
