[2024-05-13] Improved: New field for e-mail address in PUT /users/{id}

Endpoint: /api/v1/users/{id}

Method: PUT

Change: New field "email" (STRING) to update the e-mail address of the user. This can only be done if sso_only=true - which means that the user has to login via SSO. (You cannot change the e-mail address of an employee who logs in via e-mail/password.)
