Use the JSON format to specify attribute values when creating or changing a
resource. Also, use the JSON format for the results of resource information
acquisition.
When creating or adding a resource by using the POST method, or when changing or editing a resource by using the PUT method, specify resource attributes in JSON format. The supported character encoding is UTF-8.
When you use the GET method to collect resource information, responses are returned in JSON format. For API requests that get a list of resources, the response body is an array.
