Can I use event bridge with AWS Config Rules while formatting the payload sent to SNS topic to be formatted like a CloudWatch Alarm? Or use CloudWatch Alarm directly?

Question

I have a use case where I have an existing SNS topic that sends appropriate notifications to appropriate subscribers.

However, the only payload it accepts at the moment is the format of CloudWatch Alarms

Is there a way I can use event bridge to send non-complaint config rules to SNS topic while having it in a particular format? Or any service I can use to achieve this for this particular use case?

Thanks for suggestions and advice as well. Any documentation will help too.

To send AWS Config rule compliance events to an SNS topic in a format similar to CloudWatch Alarms, you can use Amazon EventBridge with an intermediary AWS Lambda function:

Create an EventBridge Rule:

Set up an EventBridge rule to capture AWS Config compliance events.

Add a Lambda Function:

Use a Lambda function to transform the captured events into the CloudWatch Alarm format.

Send to SNS Topic:

The Lambda function publishes the transformed payload to the SNS topic.

**Steps**:

EventBridge Rule:

Create a rule to capture AWS Config events (source: aws.config).
Lambda Function:

Write a Lambda function to format the AWS Config event into CloudWatch Alarm format and publish it to SNS.

SNS Topic:

Ensure your SNS topic is set up and subscribed to the notifications.
This approach allows you to integrate AWS Config events with an SNS topic that expects CloudWatch Alarm-formatted messages.
