There are events which does not give resource
* null is obtained in `responseElements`
* actual resource arn won't be available in `requestParameters`

Is there any way to get actual resource in above types of scenarios?

Answer

You can usually infer the resource from the contents of `requestParameters` or in the `responseElements`, but the contents will vary widely depending on the API call. There is no single attribute in the CloudTrail output that always indicates which resource(s) are related.
