Switching API Versions

Function

This API is used to switch the version of an API. A version is generated based on the current definition of an API when the API is published. The version records the definition and status of the API when it is published.

You can switch between multiple versions of an API, but only one version of an API takes effect in the same environment.

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions. For details about the required permissions, see Permissions Policies and Supported Actions.
