Stripe settings are correct and payments work but every time after several days i get the email message from stripe saying Webhook error - no parameters / empty payload.

The webhook is setup correctly https:///mydomain.com/oc-content/plugins/osclass_pay/payments/stripe/webhook.php
Webhook-events: payment_intent.succeeded, checkout.session.completed are set

Any idea what goes wrong?

How that email looks like?
Does it represent any error for you? missing payment or similar?

We are having trouble sending requests in live mode to a webhook endpoint associated with your account. Stripe sends webhook events to your server to notify you of activity in your Stripe account, such as a completed payout or a new invoice.

The URL of the webhook endpoint that is not working properly is: https://mydomain.be/oc-content/plugins/osclass_pay/payments/stripe/webhook.php

Error= 11 requests had other errors while sending the webhook event.

Payments are passed correctly it is only the confirmation

checkout.session.completed: HTTP status code
400 (Bad Request)
Webhook error while validating signature.

payment_intent.succeeded : HTTP status code
400 (Bad Request)
Webhook error while validating signature.

The url itself gives Webhook error - no parameters / empty payload.

Sometimes life is so easy... Removing a webhook in Stripe and creating a new one works wonders.
So my apologies for the stupid question...Now I have to start making money...Laterzz
