This can be useful in a variety of scenarios, such as: * Notifying your customer that they inadvertently broke the DNS record configuration required to use your application * Detecting if a customer is at risk for churn or might be moving to a competing solution If Entri Monitor detects a change (or deletion) of one of the records specified on a monitored domain, a notification is sent to the webhook URL that you provide on the App Settings page of the Entri Dashboard. Entri Monitor runs an hourly check, 24x7. Optionally, you can combine Entri Monitor with Entri Connect to help your user fix their DNS if Monitor detects a breaking change.
