| <title>Response Formats: XML and JSON</title> |
| <para>CloudStack supports two formats as the response to an API call. The default response is XML. If you would like the response to be in JSON, add &response=json to the Command String.</para> |
| <para>The two response formats differ in how they handle blank fields. In JSON, if there is no value for a response field, it will not appear in the response. If all the fields were empty, there might be no response at all. |
| In XML, even if there is no value to be returned, an empty field will be returned as a placeholder XML element.</para> |
