Hi Omkar,
You need to explore the following API to create a staged users first.
POST - /staged_config/access/users
Once the staged user is created, after performing a deploy change the user will be activated as deployed user and should be able to login to QRadar.
The staged configuration are not active until a deploy is performed. Must have ADMIN or ADMINMANAGER capability to call this endpoint. Users or authorized services without the ADMINMANAGER capability can only create staged users with a user role that does not contain the ADMIN capability. Users or authorized services with the ADMINMANAGER capability can create staged users with any user role.
Hope it helps.
Regards,
Prabir
