Some Common Event Handlers
- Hammad Shahid
An event handler is a method or a function that can handle user actions. An event handler is associated with a particular action so that you can write code that gets triggered when an action happens. This doc will cover the commonly used event handlers of EmpowerID objects.

After Execute | This event handler fires after the code execution of an activity completes. It can be any activity, whether a Form Activity or a Lookup Activity on your workflow designer pane. If you need to perform a task after the workflow engine has executed your activity, you can write the code in this event handler of your activity.  |
Before Execute | This event handler invokes before the activity code executes. If you want to perform any task or action before entering into your activity placed on a workflow, then use this event handler.  |
