@marcin.polanski , Happy to help.
Can you let me know if you have a basic account? If yes, you cannot create users via API then.
If you have a paid account and still facing the issue, can you let me know if it happens only when you are using powershell? Are you able to create a user with a simple cURL request?
I have an zoom admin account. I am able to create new users via web browser.
Can you check if the operation works through postman?
