Problem: In my Magento backend I get the following error: "WebHook creation failed"
Solution: Since the beginning of this year, PayPal has asked shop solicitors to support TLS 1.2. If your webshop does not support TLS 1.2, the above problem occurs. In the event that the error message nevertheless occurs, only the PayPal customer service can help you. In addition, it is possible that the access data you entered are incorrect or that you have not been activated by PayPal for PPP. You can see the status of your webhooks under "Webhook events" in your PayPal account.
