Refunds

If your payment service provider supports refund, you can easily integrate it into the module.

There should be a function called "refund" inside your module class.

The parameter passed to the function is explained in detail in the "Checkout" document.

Sample Usage

public function refund($checkout=[])
{
    $custom_id      = $checkout["id"];
    $api_key        = $this->config["settings"]["example1"] ?? 'N/A';
    $secret_key     = $this->config["settings"]["example2"] ?? 'N/A';
    $amount         = $checkout["data"]["total"];
    $currency       = $this->currency($checkout["data"]["currency"]);
    $invoice_id     = $checkout["data"]["invoice_id"] ?? 0;
    $invoice            = Invoices::get($invoice_id);
    $method_msg         = $invoice["pmethod_msg"] ?? [];
    $transaction_id     = $method_msg["Transaction ID"] ?? false;
    $force_curr     = $this->config["settings"]["force_convert_to"] ?? 0;
    if($force_curr > 0)
    {
        $amount         = Money::exChange($amount,$currency,$force_curr);
        $currency       = $this->currency($force_curr);
    }

    // Here we are making an API call.
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, "api.sample.com/refund/".$transaction_id);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'APIKEY: '.$api_key,
        'SECRET: '.$secret_key,
        'Content-Type: application/json',
    ));
    $result = curl_exec($curl);
    if(curl_errno($curl))
    {
        $result      = false;
        $this->error = curl_error($curl);
    }
    $result             = json_decode($result,true);

    if($result && $result['status'] == 'OK') $result = true;
    else
    {
        $this->error = $result['message'] ?? 'something went wrong';
        $result = false;
    }

    return $result;
}

The value to return from the function must be of the "boolean" data type.
