# PayWatch

**Overview:** The related algorithm is triggered when payments remain in a pending state and, by default, checks the payment status after 25 minutes. For payments that remain pending, it sends a notification indicating the final status. In order for this notification to be sent, you must configure the PayWatch setting at the time the payment order is created. Otherwise, Paywall will still perform the status check but will not send you a notification.
