Github audit events

Github allows to ingests GitHub events via a webhook.

I also found that the Github Enterprise provides its set of Audited actions as mentioned in below link:
https://help.github.com/enterprise/2.14/admin/articles/audited-actions/

I want to understand the difference between the GitHub events we can get via a webhook versus the Audited actions provided by Github Enterprise.

How do we get the Audited actions provided by Github Enterprise?
