AWS IoT-Data enables secure, bi-directional communication between Internet-connected things (such as sensors, actuators, embedded devices, or smart appliances) and the AWS cloud. It implements a broker for applications and things to publish messages over HTTP (Publish) and retrieve, update, and delete shadows. A shadow is a persistent representation of your things and their state in the AWS cloud.

Find the endpoint address for actions in the AWS IoT data plane by running this CLI command:

aws iot describe-endpoint --endpoint-type iot:Data-ATS

The service name used by AWS Signature Version 4 to sign requests is: iotdevicegateway .


The default endpoint data.iot.[region].amazonaws.com is intended for testing purposes only. For production code it is strongly recommended to use the custom endpoint for your account (retrievable via the iot describe-endpoint command) to ensure best availability and reachability of the service.
