Event Viewer records events completed through ​Control Center​ that are available to site administrators, such as configuration changes, login attempts, and log deliveries.

With the Event Viewer API, you can view a list of portal-visible events stored in the Event Logger system and related to a particular user account, optionally filtered by event type ID, date and time of an event, and event ID. You can also view all defined event types with related event definitions.


The API doesn't return events in real-time. It's mainly used to fetch historical data.

The API allows you to use your tools to flexibly access to the same reporting features as in Event Viewer within ​Control Center​.

Use the Event Viewer API if you want to extract event data for reporting purposes, or create an automated mechanism to manage your event data outside the ​Control Center​ user interface. For example, you can use the API to batch extract the amount of event data that is difficult to manage manually in the Event Viewer user interface.

When using the API, make sure to use IDs for your integration, and not names or descriptions.


Event data is available for 90 days, with the exception of Upload ECCU File and LDS Successful delivery events. These events have an expiration period of 7 days. If you'd like to retain event data older than 90 days, consider using the Event Viewer API to list and archive the data.
