API Instructions (OpenStack Nova APIs)

  • For details about network service APIs, see Virtual Private Cloud API Reference.
  • For the native OpenStack APIs not provided in this document (such as the API used to attach EVS disks to a BMS), use the native OpenStack APIs of ECS. For details, see Elastic Cloud Server API Reference.
  • To support function extension, Nova APIs can be distinguished by version. There are two types of versions:
    • Major version: independent URL
    • Microversion: Used by the HTTP request header X-OpenStack-Nova-API-Version. Since microversion 2.27, the new microversion header OpenStack-API-Version has been supported.
