Hi,

What I want is to check user’s groups and read group members programmatically, with scopes I have set in roles.  
I don’t know if there is a proper way to do that, and I try to use API to request from the hub. And the problem is where I can get an authenticated API token with full access to the JupyterHub API for this.  
I have tried `$JUPYTERHUB_API_TOKEN` but it doesn’t work.  
One way is to get from the web page. But since We want do the checks programmatically and maybe in postStart lifehooks, how can I do it properly?

Thanks for your help.

I may found the solution, and [Understanding token scope difference](https://discourse.jupyter.org/t/understanding-token-scope-difference/10467) helps a lot.

```auto
c.JupyterHub.load_roles = [
 {
   'name': 'server',
   'scopes': ['all'],
 }
]

```
