# Responding to an event with Amazon SNS
<a name="event-sns-response"></a>

This section shows how to configure Amazon SNS to send a text notification whenever ACM generates a health event.

Complete the following procedure to configure a response.

**To create a Amazon EventBridge rule and trigger an action**

1. Create an Amazon EventBridge rule. For more information, see [Creating Amazon EventBridge rules that react to events](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-create-rule.html).

   1. In the Amazon EventBridge console at [https://console.aws.amazon.com/events/](https://console.aws.amazon.com/events/), navigate to the **Events** > **Rules** page and choose **Create rule**. 

   1. On the **Create rule** page, select **Event Pattern**.

   1. For **Service Name**, choose **Health** from the menu.

   1. For **Event Type**, choose **Specific Health events**.

   1. Select **Specific service(s)** and choose **ACM** from the menu.

   1. Select **Specific event type category(s)** and choose **accountNotification**.

   1. Choose **Any event type code**.

   1. Choose **Any resource**.

   1. In the **Event pattern preview** editor, paste the JSON pattern emitted by the event. This example uses the pattern from the [AWS health events](supported-events.md#health-event) section.

   ```
   {
      "source":[
         "aws.health"
      ],
      "detail-type":[
         "AWS Health Event"
      ],
      "detail":{
         "service":[
            "ACM"
         ],
         "eventTypeCategory":[
            "scheduledChange"
         ],
         "eventTypeCode":[
            "AWS_ACM_RENEWAL_STATE_CHANGE"
         ]
      }
   }
   ```

1. Configure an action.

   In the **Targets** section, you can choose from among many services that can immediately consume your event, such as Amazon Simple Notification Service (SNS), or you can choose **Lambda function** to pass the event to customized executable code. For an example of an AWS Lambda implementation, see [Responding to an event with a Lambda function](event-lambda-response.md).
