Queries the details of all RAM users.


You can call the following API operations to query the information about all RAM users:

  • ListUsers: queries the details of all RAM users.
  • ListUserBasicInfos: queries the basic information about all RAM users. The basic information includes only the logon names (UserPrincipalName), display names (DisplayName), and user IDs (UserId).


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
