Redirect user to payment Gateway url

Halo Everyone! the following is the code am having that is giving status:200.

$response = curl_exec($curl); curl_close($curl); $newsData = json_decode($response); if (isset($newsData->paymentRequestId) && $newsData->paymentRequestId !== '' ) { // dd($newsData->url); return redirect($newsData->url); }

the issue is am having a problem with redirecting users to payment gateway afterwards.
