In an Identity Management system, any action performed by a user or system is called an operation or Event. Examples of Events are CREATING users, updating users, creating password policy, and so on.

Types:

1. Pre-process Event Handler
2. Post-Process Event Handler

Pre-process Event Handler: Mostly Pre-process Event Handlers are USED for Validation Purpose.

Post-process Event Handler: Post-process Event Handlers are written MAINLY when there is a need of making changes internally after any event is triggered in OIM. 

For E.g.: Assign Role according to Organization, AUTO Assign an email ID using Firstname and Lastname of user and so on.
