notification_configuration[:lambda_function_configurations] = lambda_configurations

Add queue

qc = {}

qc[:queue_arn] = 'my-topic-arn' qc[:events] = events queue_configurations = [] queue_configurations << qc

notification_configuration[:queue_configurations] = queue_configurations

Add topic

tc = {}

notification_configuration[:topic_configurations] = topic_configurations

req[:notification_configuration] = notification_configuration
