EventBridge Rule not triggering SNS Topic & Lambda Function

Question

I have created some resources in ap-south-1 region which is not behaving in expected manner.

I have an RDS Instance for which password is managed by AWS Secrets Manager. Whenever the password is changed I can see RotationSucceeded event in Cloudtrail. Accordingly I have created an EventBridge rule named RDSPasswordRotation that matches the RotationSucceeded event and an SNS Topic named SecretRotationRDS (To notify via mail) & Lambda Function 
named Jenkins_Pipeline_Trigger_P-3-7 (For Jenkins Build) is configured as targets. I have provided all the necessary permissions but the EventBridge rule is neither invoking the SNS topic nor the Lambda Function.

Can anyone please look into this issue.

The event pattern selected for the EventBridge rule named RDSPasswordRotation is :

{
  "source": ["aws.secretsmanager"],
  "detail-type": ["AWS API Call via CloudTrail"],
  "detail": {
    "eventSource": ["secretsmanager.amazonaws.com"],
    "eventName": ["RotationSucceeded"]
  }
}

Accepted Answer

First, do make sure you have at least one CloudTrail trail enabled (you should double-check but I believe first trail is always free). Otherwise CloudTrail will not be passing events to EventBridge.

After that, I'd recommend creating a more generic rule to grab a sample event that you like. You can forward this to a temporary CloudWatch Log record. Once you have a sample event, you can follow this guide to test your event-pattern https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-pattern-sandbox.html.

Hello.

Change "detail-type" to "AWS Service Event via CloudTrail" as shown in the stackoverflow answer below.

```
{
    "detail-type": [
      "AWS Service Event via CloudTrail"
    ],
    "detail": {
      "eventSource": [
        "secretsmanager.amazonaws.com"
      ],
      "eventName": [
        "RotationSucceeded"
      ]
    }
  }
```

I think the event pattern in the following document will be helpful.  
https://docs.aws.amazon.com/secretsmanager/latest/userguide/monitoring-eventbridge.html#monitoring-eventbridge_examples-rotations  
```
{
    "source": ["aws.secretsmanager"],
    "$or": [
        { "detail-type": ["AWS API Call via CloudTrail"] }, 
        { "detail-type": ["AWS Service Event via CloudTrail"] }
    ],
    "detail": {
        "eventSource": ["secretsmanager.amazonaws.com"],
        "eventName": ["PutSecretValue", "UpdateSecret", "RotationSucceeded"]
    }
}
```
