            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic-2"
        },
        {
            "AutoScalingGroupName": "my-asg",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic"

Example 1: To describe a specified number of notification configurations

To return a specific number of notification configurations, use the max-items parameter.

aws autoscaling describe-notification-configurations \
    --auto-scaling-group-name my-auto-scaling-group \
    --max-items 1

Output:

{
    "NotificationConfigurations": [
        {
            "AutoScalingGroupName": "my-asg",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic-2"
        },
        {
            "AutoScalingGroupName": "my-asg",
            "NotificationType": "autoscaling:TEST_NOTIFICATION",
            "TopicARN": "arn:aws:sns:us-west-2:123456789012:my-sns-topic"
        }
    ]
}

If the output includes a NextToken field, there are more notification configurations. To get the additional notification configurations, use the value of this field with the starting-token parameter in a subsequent call as follows.

aws autoscaling describe-notification-configurations \
    --auto-scaling-group-name my-asg \
    --starting-token Z3M3LMPEXAMPLE
