I have this stripe file StripePayment.php
<?php
require_once 'vendor/autoload.php';
use StripeStripe;
use StripeCustomer;
use StripeApiOperationsCreate;
use StripeCharge;
class StripePayment
{
private $apiKey;
private $stripeService;
public function __construct()
{
require_once "config.php";
$this->apiKey = STRIPE_SECRET_KEY;
$this->stripeService = new StripeStripe();
$this->stripeService->setVerifySslCerts(false);
$this->stripeService->setApiKey($this->apiKey);
}
public function addCustomer($customerDetailsAry)
{
$customer = new Customer();
$customerDetails = $customer->create($customerDetailsAry);
return $customerDetails;
}
public function chargeAmountFromCard($cardDetails)
{
$customerDetailsAry = array(
'email' => $cardDetails['email'],
'source' => $cardDetails['token']
);
$customerResult = $this->addCustomer($customerDetailsAry);
$charge = new Charge();
$cardDetailsAry = array(
'customer' => $customerResult->id,
'amount' => $cardDetails['amount']*100 ,
'currency' => $cardDetails['currency_code'],
'description' => $cardDetails['item_name'],
'metadata' => array(
'order_id' => $cardDetails['item_number']
)
);
$result = $charge->create($cardDetailsAry);
return $result->jsonSerialize();
}
}
and i am charging the card like this
<?php
ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');
error_reporting(E_ALL);
require_once "config.php";
if (!empty($_POST["token"])) {
require_once 'StripePayment.php';
$stripePayment = new StripePayment();
$stripeResponse = $stripePayment->chargeAmountFromCard($_POST);
require_once "DBController.php";
$dbController = new DBController();
$amount = $stripeResponse["amount"] /100;
$param_type = 'ssdssss';
$param_value_array = array(
$_POST['email'],
$_POST['item_number'],
$amount,
$stripeResponse["currency"],
$stripeResponse["balance_transaction"],
$stripeResponse["status"],
json_encode($stripeResponse)
);
This code is able to charge cards but can’t charge cards where 3D/SCA is required i.e European cards.
My question, is there a way i can request stripe to redirect the user to the card issuing bank for authentication so that the user can authorize the transaction?
My stripe form code looks like this
<form id="frmStripePayment" action=""
method="post">
<div class="field-row">
<label>Card Holder Name</label> <span
id="card-holder-name-info" class="info"></span><br>

According to the docs on how to manually require the user to be redirected to the bank url for further authentication https://stripe.com/docs/payments/3d-secure#manual-three-ds
next_action: {
type: 'redirect_to_url',
redirect_to_url: {
url: 'https://hooks.stripe.com/...',
return_url: 'https://example.com'
}
}
does the stripe sdk automatically know the bank url to redirect to or who feeds that info?

Answer
The bank-hosted authentication URL is handled by redirecting through that redirect_to_url.url, or alternatively is managed automatically when using Stripe’s Payment Intent API with confirmCardPayment in Stripe.js v3 (migration guide). If you use confirmCardPayment, you yourself don’t need to manage the redirect at all. This is the recommendation approach to supporting 3D Secure.
You can support 3DS using the Sources API, but this is deprecated and no longer recommended.
