# Automating the Amazon Chime SDK with EventBridge
<a name="automating-chime-with-cloudwatch-events"></a>

Amazon EventBridge lets you automate your AWS services and respond automatically to system events, such as application availability issues or resource changes. For more information about the meeting events, see [Meeting events](https://docs.aws.amazon.com/chime/latest/dg/using-events.html) in the *Amazon Chime SDK Developer Guide*.

When the Amazon Chime SDK generates events, it sends them to EventBridge for *best effort delivery*, meaning the Amazon Chime SDK tries to send all events to EventBridge, but in rare cases an event might not be delivered. For more information, refer to [Events from AWS services](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-service-event.html) in the *Amazon EventBridge User Guide*.

**Note**  
If you need to encrypt data, you must use Amazon S3-Managed Keys. We don't support server-side encryption using Customer Master Keys stored in the AWS Key Management Service. 

## Automating Amazon Chime SDK Voice Connectors with EventBridge
<a name="events-cvc"></a>

The actions that can be automatically triggered for Amazon Chime SDK Voice Connectors include the following:
+ Invoking an AWS Lambda function
+ Launching an Amazon Elastic Container Service task
+ Relaying the event to Amazon Kinesis Video Streams
+ Activating an AWS Step Functions state machine
+ Notifying an Amazon SNS topic or an Amazon SQS queue

Some examples of using EventBridge with Amazon Chime SDK Voice Connectors include:
+ Activating a Lambda function to download audio for a call after the call is ended.
+ Launching an Amazon ECS task to enable real-time transcription after a call is started.

For more information, see the [Amazon EventBridge User Guide](https://docs.aws.amazon.com/eventbridge/latest/userguide/).
