The name of the thing.

The response's http status code.

The state information, in JSON format.

The topic name of the retained message to retrieve.

The Epoch date and time, in milliseconds, when the retained message was stored by IoT.

The Base64-encoded message payload of the retained message body.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

The quality of service (QoS) level used to publish the retained message.

The topic name to which the retained message was published.

The response's http status code.

The name of the shadow.

The name of the thing.

The state information, in JSON format.

The response's http status code.

The token to retrieve the next set of results.

The result page size.

The name of the thing.

The token to use to get the next set of results, or null if there are no additional results.

The list of shadows for the specified thing.

The Epoch date and time the response was generated by IoT.

The response's http status code.

The maximum number of results to return at one time.

To retrieve the next set of results, the nextToken value from a previous response; otherwise null to receive the first set of results.

The token for the next set of results, or null if there are no additional results.

A summary list the account's retained messages. The information returned doesn't include the message payloads of the retained messages.

The response's http status code.

A UTF-8 encoded string that describes the content of the publishing message.

The base64-encoded binary data used by the sender of the request message to identify which request the response message is for when it's received. correlationData is an HTTP header value in the API.

A user-defined integer value that represents the message expiry interval in seconds. If absent, the message doesn't expire. For more information about the limits of messageExpiry, see Amazon Web Services IoT Core message broker and protocol limits and quotas from the Amazon Web Services Reference Guide.

The message body. MQTT accepts text, binary, and empty (null) message payloads.

Publishing an empty (null) payload with retain = true deletes the retained message identified by topic from Amazon Web Services IoT Core.

An Enum string value that indicates whether the payload is formatted as UTF-8. payloadFormatIndicator is an HTTP header value in the API.

The Quality of Service (QoS) level. The default QoS level is 0.

A UTF-8 encoded string that's used as the topic name for a response message. The response topic is used to describe the topic which the receiver should publish to as part of the request-response flow. The topic must not contain wildcard characters.

A Boolean value that determines whether to set the RETAIN flag when the message is published.

Setting the RETAIN flag causes the message to be retained and sent to new subscribers to the topic.

Valid values: true | false

Default value: false

A JSON string that contains an array of JSON objects. If you don’t use Amazon Web Services SDK or CLI, you must encode the JSON string to base64 format before adding it to the HTTP header. userProperties is an HTTP header value in the API.

The following example userProperties parameter is a JSON string which represents two User Properties. Note that it needs to be base64-encoded:

[{"deviceName": "alpha"}, {"deviceCnt": "45"}]

The size of the retained message's payload in bytes.

The quality of service (QoS) level used to publish the retained message.

The topic name to which the retained message was published.
