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 checks your monitored records on an ongoing basis. ## How domains are enrolled Domains added through [`showUnify()`](/unify/overview) are enrolled in Entri Monitor automatically. No configuration is needed. To opt out, pass `monitor: false` in the `showUnify()` config. For the standalone flows, `connectDomain()` (Entri Connect) and `purchaseDomain()` (Entri Sell), enrollment is opt-in: pass `monitor: true` in the configuration, either for the whole domain or per record. See [Monitor configuration](/monitor/configuration). Optionally, you can combine Entri Monitor with Entri Connect to help your user fix their DNS if Monitor detects a breaking change.
