                Our integration creates a specific webhook on your Paypal account that we use to report back
                transactions to our system. If you delete this webhook, we will not be able to report back and
                you should Uninstall and Install the app again for this to work again. Uninstalling the app
                won&apos;t delete your current event type price/currency configuration but you would not be
                able to receive bookings.
