User password change from api not reflected

Hello.
Unable to change user password from api.(I’m using cms2.2.1)
Other items were reflected, but only the user’s password was not reflected no matter how many times I tried.

Please let me know if I forget anything.
Thank you.

Only super admin users can change passwords of other users (via the API or otherwise). Users can only update their own passwords through the web portal for security reasons.
