AWS IoT rule actions specify what to do when a rule is invoked. You can define actions to send data to an Amazon DynamoDB database, send data to Amazon Kinesis Data Streams, invoke an AWS Lambda function, and so on. AWS IoT supports the following actions in AWS Regions where the action's service is available.
Rule action Description Name in API Apache Kafka Sends a message to an Apache Kafka cluster.kafka CloudWatch alarms Changes the state of an Amazon CloudWatch alarm. cloudwatchAlarm CloudWatch Logs Sends a message to Amazon CloudWatch Logs. cloudwatchLogs CloudWatch metrics Sends a message to a CloudWatch metric. cloudwatchMetric DynamoDB Sends a message to a DynamoDB table. dynamoDB DynamoDBv2 Sends message data to multiple columns in a DynamoDB table. dynamoDBv2 Elasticsearch Sends a message to an OpenSearch endpoint. OpenSearch HTTP Posts a message to an HTTPS endpoint. http IoT Analytics Sends a message to an AWS IoT Analytics channel. iotAnalytics AWS IoT Events Sends a message to an AWS IoT Events input. iotEvents AWS IoT SiteWise Sends message data to AWS IoT SiteWise asset properties. iotSiteWise Firehose Sends a message to a Firehose delivery stream. firehose Kinesis Data Streams Sends a message to a Kinesis data stream. kinesis Lambda Invokes a Lambda function with message data as input. lambda Location Sends location data to Amazon Location Service. location OpenSearch Sends a message to an Amazon OpenSearch Service endpoint. OpenSearch Republish Republishes a message to another MQTT topic. republish S3 Stores a message in an Amazon Simple Storage Service (Amazon S3) bucket. s3 Salesforce IoT Sends a message to a Salesforce IoT input stream. salesforce SNS Publishes a message as an Amazon Simple Notification Service (Amazon SNS) push notification. sns SQS Sends a message to an Amazon Simple Queue Service (Amazon SQS) queue. sqs Step Functions Starts an AWS Step Functions state machine. stepFunctions Timestream Sends a message to an Amazon Timestream database table. timestream
Notes
Define the rule in the same AWS Region as another service's resource so that the rule action can interact with that resource.
The AWS IoT rules engine might make multiple attempts to perform an action if intermittent errors occur. If all attempts fail, the message is discarded and the error is available in your CloudWatch Logs. You can specify an error action for each rule that is invoked after a failure occurs. For more information, see Error handling (error action).
Some rule actions activate actions in services that integrate with AWS Key Management Service (AWS KMS) to support data encryption at rest. If you use a customer-managed AWS KMS key (KMS key) to encrypt data at rest, the service must have permission to use the KMS key on the caller's behalf. To learn how to manage permissions for your customer managed KMS key, see the data encryption topics in the appropriate service guide. For more information about customer managed KMS keys, see AWS Key Management Service concepts in the AWS Key Management Service Developer Guide.
