Request and response formats

The OpenStack Compute API only supports JSON request and response formats, with a mime-type of application/json. As there is only one supported content type, all content is assumed to be application/json in both request and response formats.

Request and response examples

The examples below show a request body in JSON format.

Example: JSON request with headers
