You can’t assign the ID.

There is an external ID route:

```
    get "#{root_path}/by-external/:external_id" => "users#show", constraints: { external_id: /[^\/]+/ }

```

If you enable site setting `sso_overrides_username` (I think that’s a thing), you don’t need to change the username with the API.
