Good afternoon, I want to get information about the conference participants, for this I decided to use the zoomus for python library.  
But when I have done everything, I get an error:  
**\<Response [401]\>**

**CODE**  
I use this code:

```
import json
from zoomus import ZoomClient

client = ZoomClient('API_KEY', 'API_SECRET')
print(client)
user_list_response = client.user.list()
user_list = json.loads(user_list_response.content)

for user in user_list['users']:
    user_id = user['id']
    print(json.loads(client.meeting.list(user_id=user_id).content))

```

API\_KEY and API\_SECRET i get from my JWT  
I created the JWT in advance and activated it.

I was trying this code, but i have the same problem.

```
import json
from zoomus import ZoomClient

client = ZoomClient('---', '---')

user_list_response = client.user.list()
user_list = json.loads(user_list_response.content)
print(user_list)

```

**OUTPUT**  
{‘code’: 124, ‘message’: ‘Invalid access token.’}

I would be glad if you could help me with this.

Hi @nitagas2005,

Can you share which endpoint you’re sending your request to? Some endpoints have prerequisites, such as a paid plan, etc., which could be causing this invalid token error.

Thanks,  
Will
