Implementation for accessing IotData

IoT data

IoT data enables secure, bi-directional communication between Internet-connected things (such as sensors, actuators, embedded devices, or smart appliances) and the Amazon Web Services 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 Amazon Web Services cloud.

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

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

The service name used by Amazon Web ServicesSignature Version 4 to sign requests is: iotdevicegateway.
