    response = client.stop_instance(
    instanceName='INSTANCE-NAME'
)
    return {
        'statusCode': 200,
        'body': json.dumps('Lambda has stopped instance')
    }
```

#### Code to START Lightsail Instance:

```python
# TO START
import json
import boto3
def lambda_handler(event, context):
    client = boto3.client('lightsail', region_name='REGION-NAME')

    instanceName='INSTANCE-NAME'
)
    return {
