[soly2014]

[iZaL]

Can you give a bit more explanation ? or maybe code example ?

[soly2014]

well , i am working with laravel framework

Route::get('/', function () {

$responseURL = 'http://localhost/payment/response';
$successURL = 'http://localhost/payment/success';
$errorURL = 'http://localhost/payment/error';
$knetAlias = 'salwa';
$resourcePath = public_path('/');
$amount = 150;
$trackID = str_random(6); 

try {

    $knetGateway = new IZaL\Knet\KnetBilling([
        'alias'        => $knetAlias,
        'resourcePath' => $resourcePath
    ]);

    $knetGateway->setResponseURL($successURL);
    $knetGateway->setErrorURL($errorURL);
    $knetGateway->setAmt($amount);
    $knetGateway->setTrackId($trackID);

    $knetGateway->requestPayment();
    $paymentURL = $knetGateway->getPaymentURL();
    // helper function to redirect
    return redirect($paymentURL);

} catch (\Exception $e) {

    // to debug error message 
    dd(var_dump($e->getMessage()));
    
    return redirect('payment/error');
}

});

Route::get('payment/response',function(){
return 'payment/response';
});

Route::get('payment/success',function(){
return 'payment/success';
});

Route::get('payment/error',function(){
return 'payment/error';
});

after going to knet website and process payment, the website always redirected me to error page @iZaL

[soly2014]

@iZaL it returns 404 error

[iZaL]

for Laravel Implementation check the gist

[iZaL]

that is a raw implementation, but you will get the idea..

[soly2014]

@iZaL i just wanna tell you the error comes after redirecting back from knet website so what's the reason

[iZaL]

are you using test credentials ? are you testing in online or just localhost ? Knet response will fail if it cannot reach the redirect host. so you have to test your code putting it online

[soly2014]

i tested online

[soly2014]

with test credentials

[soly2014]

and the bank process the payment and then redirect me always to error page ? i don't know why ??? @iZaL

[iZaL]

show the response method ? please note that your response method should return the string
return "REDIRECT=" . $redirectURL . $urlParams;"

with exact format. you cannot return anything else.
