Calling Method

Public parameters

Public request parameters are required for every API interface. Developers must include these parameters every time they send a request using the Volcano Engine OpenAPI. Otherwise, the request will fail. The first letters of common request parameters are all capitalized to distinguish them from other request parameters.
