I am trying to update database.
I have set up the webhook in stripe in test mode and send a "invoice.payment_succeeded" test webhook to file.but it shows response "none" in stripe output.
What have i done wrong, here is the webhook file, please someone help me, i am very stuck at this. any help will be appreciate...
<?php
include '../admin/include/functions.php';
require_once('Stripe/lib/Stripe.php');
require_once 'stripe_secret.php';
// Retrieve the request's body and parse it as JSON
$input = #file_get_contents("php://input");
$event_json = json_decode($input);
$event_id = $event_json->id;
if(isset($event_json->id)) {
try {
Stripe::setApiKey($stripe['secretkey']);
$event = Stripe_Event::retrieve($event_id);
var_dump($event);
$invoice = $event->data->object;
if($event->type == 'invoice.payment_succeeded') {
$customer = Stripe_Customer::retrieve($invoice->customer);
$email = $customer->email;
$customerid = $customer->id;
/*$amount = $invoice->amount / 100;*/
$expiry = $invoice->period->end;
$expiredate = date('Y-d-m', $expiry);
$userup = $obj->run_query("UPDATE users SET Expiry_Date = '$expiredate' WHERE user_stripe_id = '$customerid' ");
if ($userup) {
echo "User Date extended";
}
// send a invoice notice email here
}
if($event->type == 'invoice.payment_failed') {
$obj->run_query("UPDATE users SET Status = '0' WHERE user_stripe_id = '$customerid' ");
echo "User membership expired";
}
}
catch(Stripe_CardError $e) {
}
catch (Stripe_InvalidRequestError $e) {
// Invalid parameters were supplied to Stripe's API
} catch (Stripe_AuthenticationError $e) {
// Authentication with Stripe's API failed
// (maybe you changed API keys recently)
} catch (Stripe_ApiConnectionError $e) {
// Network communication with Stripe failed
} catch (Stripe_Error $e) {
// Display a very generic error to the user, and maybe send
// yourself an email
} catch (Exception $e) {
// Something else happened, completely unrelated to Stripe
}
}
http_response_code(200);
?>

The test webhooks from the test webhook button sends a webhook with the right format but all the values are null / zero / etc. Thus your line that does $obj->run_query("UPDATE users SET Expiry_Date = '$expiredate' WHERE user_stripe_id = '$customerid' "); will return a falsey result. This means you don't echo anything and just send back an empty 200 response.
