Why my Stripe Webhook function is not working(test mode)? - php

Question

I has create a webhook php to trigger the paymentintent event status. I had successfully tigger it but the function of detected event is no working which i just want to redirect to another page if successful or not. I try to echo text, it also not showing. I can see the response body(show the text that i want to echo" in the dashboard of Stripe. Did i misunderstanding the concept of it ? This is my code:
<?php
/*
Template Name: webhook
*/
include_once(get_template_directory_uri().'/customFile/stripe-php-7.71.0/init.php');
\Stripe\Stripe::setApiKey('xxx'); // this is true, i just replace with xxx
$payload = #file_get_contents('php://input');
$event = null;
$paymentstatus = "Payment Failed";
try {
$event = \Stripe\Event::constructFrom(
json_decode($payload, true)
);
} catch(\UnexpectedValueException $e) {
// Invalid payload
http_response_code(400);
exit();
} catch(\Stripe\Exception\SignatureVerificationException $e) {
// Invalid signature
http_response_code(400);
exit();
}
// Handle the event
switch ($event->type) {
case 'payment_intent.succeeded':
$paymentIntent = $event->data->object; // contains a \Stripe\PaymentIntent
//handlePaymentIntentSucceeded($paymentIntent);
echo"Success";
echo "<script>location.href='http://localhost/wordpress/';</script>";
break;
case 'payment_intent.payment_failed':
$paymentMethod = $event->data->object; // contains a \Stripe\PaymentMethod
//handlePaymentMethodAttached($paymentMethod);
echo "<script>location.href='http://localhost/wordpress/shop/';</script>";
break;
}
http_response_code(200);

Webhooks are requests that come from Stripe to your web server. There's no user attached to these events so trying to redirect after you receive a webhook event makes no sense. All that's happening is you're sending a <script> string back to Stripe, who promptly ignores it because all they are about is the response status code.
If you want to redirect your user after they've made a successful payment, you should either that on the client after they've confirmed the PaymentIntent or in your success_url if you're using Checkout.
