Hey
Event Notifications are a form of webhook, I use http://webhook.site/ to test this out.
You can then enable the options you want to listen for. When a device is deleted, wiped, changed, it will post to your web hook listener and you can then do something with it. Its really designed for when you have some internal middleware doing lookups/API Calls based on events that happen on devices.
One example I've seen is generating certificates from a custom CA, and delivering them to a device using the UEM API. Another is updating CMDB records based on the user details in the request, with the device details posted.
In this example, I updated the friendly name of my device.
{"EventId":642,"EventType":"Device Friendly Name","DeviceId":9612,"DeviceFriendlyName":"adam iPhone iOS 13.3.1 GRY9 Test","EnrollmentEmailAddress":"redacted","EnrollmentUserName":"adam","EventTime":"2020-02-12T11:32:05.5981164Z","EnrollmentStatus":"Enrolled","CompromisedStatus":"","CompromisedTimeStamp":"2020-02-12T11:32:06.296479Z","ComplianceStatus":"Compliant","PhoneNumber":"","Udid":"redacted","SerialNumber":"redacted","MACAddress":"redacted","DeviceIMEI":"redacted","EnrollmentUserId":604126,"AssetNumber":"redacted","Platform":"Apple","OperatingSystem":"13.3.1","Ownership":"CorporateDedicated","SIMMCC":"","CurrentMCC":"","OrganizationGroupName":"AMEMM","DeviceUUID":"redacted","EnrollmentUserUUID":""}
The basic docs are here System / Advanced / API / Event Notifications. My advice would be to leverage webhook.site and test out the events for yourself.
