| <p>The structure of the examples in this section is as follows:</p> |
| |
| <h2 id="command">Command</h2> |
| |
| <p>Each example always starts with a command message that initiates an operation at Ditto (e.g. create a thing, retrieve a thing).</p> |
| |
| <div class="language-json highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="p">{</span><span class="w"> |

| |
| <h2 id="response">Response</h2> |
| |
| <p>A command always has a response which either reports the success or the failure. The example contains the success response. |
| See Thing Error responses for examples of messages that will be returned in case of an error.</p> |

| |
| <h2 id="event">Event</h2> |
| |
| <p>If Ditto triggers an event (e.g. Thing created, Attribute modified) as a result of the executed command, an example of such an event is also demonstrated.</p> |
