About payten [NESTPAY]payment integration to Laravel 10 project

I get an error when integrating the payten(nestpay) payment infrastructure into my Laravel 10 project. I am using the 3D PAY HOSTING model.

Receiving payment in normal php code works smoothly. (I also added the document codes here.) I created a sample structure in Laravel. 3d payment returns 405 when redirecting the post. ssl gives an error that I run on my installed website.

The example I created in laravel 10 project.

routes/web.php code

Route::get('/payment', [PaymentController::class, 'showPaymentForm'])->name('payment.form'); Route::post('/payment/process', [PaymentController::class, 'processPayment'])->name('payment.process'); Route::post('/payment/response', [PaymentController::class, 'responsepayment'])->name('payment.response');

App\Http\Controllers\PaymentController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request; use Illuminate\Support\Facades\Http;

class PaymentController extends Controller { public function showPaymentForm() { return view('request'); } public function responsepayment() { return view('response'); }

public function processPayment(Request $request)
{
    // post data create hash
    $postParams = $request->all();


    $hashStr = $this->makeHashString($postParams);
    $calculatedHashValue = hash('sha512', $hashStr);
    $hash = base64_encode(pack('H*', $calculatedHashValue));

    $postParams['HASH'] = $hash;

    $response = Http::post('<poslink>/fim/est3Dgate', $postParams);


    if ($response->successful()) {
        // 3D safe page redirect
        return redirect()->away('<poslink>/fim/est3Dgate');
    } else {
        return redirect()->route('payment.form')->with('error', 'Payment Fail.');
    }
}

private function makeHashString($postParams)
{
    $hashStr = '';

    foreach ($postParams as $key => $value) {
        if ($key !== 'HASH') {
            $hashStr .= $value . '|';
        }
    }

    $storeKey = "TEST1234";
    $escapedStoreKey = str_replace("|", "\|", str_replace("\", "\\", $storeKey));
    $hashStr .= $escapedStoreKey;

    return $hashStr;
}

}
