# Creating Entity Events

## Overview

Entity Events run a Flow when certain events occur to an Entity, such as the saving of an Entity. For example, an Entity event could be to insert an audit record into a database or directory when an Entity is deleted that records details such as who deleted the Entity. Entity Events require a Data Structure with a [Configuration Folder](/v9/docs/configuration-folder).

## Event Types

| Type of Events | Function |
| --- | --- |
| **After Delete Flow** | A Flow runs after a Delete is made to the Entity to save the changes. |
| **After Save Flow** | A Flow runs to save the changes after a flow is changed. |
| **Before Delete Flow** | A Flow runs before a Delete is made to an Entity to save the data. |
| **Before Save Flow** | A Flow runs before a save is made to an Entity to save the data. |

Entity Events will run every time an Entity of the type is saved. Please take care to not use any save or assigned steps that could cause this Entity to be saved in a cycle.
