# Using Triggers

**This section explores triggers and their applicability to Entity records. By the end of this section, you will be able to create triggers for created, updated, and deleted entity records.**

## Triggers

* Triggers are events that users can define to be initiated after a record is created, updated, or deleted in an entity. 
* Triggers are defined within the Entity template under the Triggers tab.

* Triggers are of 3 types: 
  * After Create: An After Create trigger can be defined to initiate actions after a record is created. 
  * After Update: An After Update trigger can be defined to initiate actions after a record is updated. 
  * After Delete: An After Delete trigger can be defined to initiate actions after a record is deleted. 
* Triggers contain predefined variables based on the type of trigger. 
* Users can define additional variables as required.
