# Supported actions to receive data and trigger actions in AWS IoT Events
<a name="iotevents-supported-actions"></a>

AWS IoT Events can trigger actions when it detects a specified event or transition event. You can define built-in actions to use a timer or set a variable, or send data to other AWS resources. Learn how to configure and customize these actions to create automated responses to your various IoT events.

**Note**  
When you define an action in a detector model, you can use expressions for parameters that are string data type. For more information, see [Expressions](https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-expressions.html).
