After a Pay by Link payment, just like with other integration types, you receive the result of the payment through a notification webhook. After the shopper selects a payment method and completes the payment, the notification is sent to the endpoint on the server. Also if the payment is not successful you will get a notification. However, in the standard notification you will not be able to specifically see it is about a Pay By Link payment. Another way to get notified of a successful Pay by Link payment method is to use the email notification functionality. Please follow the steps described here: Pay by Link email updates. This will allow you to get payment status updates sent to your email.
