# Sample Function

The following is a sample class and Lambda function that receives Amazon SNS event record data as input, writes some of the record data to CloudWatch Logs, and responds with a 200 status and the same body as the request. (Note that by default anything written to Console will be logged as CloudWatch Logs events.)

```go
import (
	"context"
	"fmt"

	"github.com/aws/aws-lambda-go/events"
)

func handler(ctx context.Context, snsEvent events.SNSEvent) {
	for _, record := range snsEvent.Records {
		snsRecord := record.SNS

		fmt.Printf("[%s %s] Message = %s \n", record.EventSource, snsRecord.Timestamp, snsRecord.Message)
	}
}
```
