added Client ID and Secret and save :
The specified credentials are valid
But on top of that I also see:
Webhook was not created, so some functions may not work correctly (see details in the log. Please ensure that your store is under SSL, PayPal service doesn't send requests to unsecured sites.)
I don't see any place to add webhook URL on this page. Also the error on log is below:
Payments.PayPalCommerce error:
{"name":"VALIDATION_ERROR","message":"Invalid data provided","debug_id":"b67e10003eac3","information_link":"https://developer.paypal.com/docs/api/webhooks/#errors","details":[{"field":"url","location":"body","issue":"Not a valid webhook URL"}],"links":[]}
So I have to add it on paypal page if so what will be the URL ?
