/// Constructs a fluent builder for the [`SendDirectMessage`](crate::operation::send_direct_message::builders::SendDirectMessageFluentBuilder) operation.

MQTT client IDs must be URL encoded (percent-encoded) when they contain characters that are not valid in HTTP requests, such as spaces, forward slashes (/), and UTF-8 characters. For more information, see <a href="https://docs.aws.amazon.com/general/latest/gr/iot-core.html#message-broker-limits">Amazon Web Services IoT Core message broker and protocol limits and quotas</a>.</p><br>

If delivery confirmation is not received within the specified <code>timeout</code> period, the API returns HTTP 504.</p> <p>When set to <code>false</code>, the API delivers the message at QoS 0 and returns after Amazon Web Services IoT Core attempts to deliver the message.</p> <p>Valid values: <code>true</code> | <code>false</code></p> <p>Default value: <code>false</code></p><br>

This parameter is only used when <code>confirmation</code> is set to <code>true</code>. If <code>confirmation</code> is <code>false</code>, this parameter is ignored.</p> <p>The total API response time may be higher than this value due to internal processing. Set your HTTP client timeout to a value greater than this parameter.</p> <p>Valid range: 1 to 15 seconds.</p> <p>Default value: <code>5</code> seconds.</p><br>
/// - [`payload(Blob)`](crate::operation::send_direct_message::builders::SendDirectMessageFluentBuilder::payload) / [`set_payload(Option<Blob>)`](crate::operation::send_direct_message::builders::SendDirectMessageFluentBuilder::set_payload):<br>required: **false**<br><p>The message body.

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. <code>userProperties</code> is an HTTP header value in the API.</p> <p>For MQTT 3.1.1 clients, user properties are silently dropped.</p> <p>The following example <code>userProperties</code> parameter is a JSON string which represents two User Properties. Note that it needs to be base64-encoded:</p> <p><code>\[{"deviceName": "alpha"}, {"deviceCnt": "45"}\]</code></p><br>
