Do I need a separate license to use the Webex Meeting API?

[cleans2002]

I want to create a meeting to use webex meeting api, but i couldn't that.
I use Python code to send requests with authorization token in hearder.

api_url = "https://webexapis.com/v1/meetings"
headers = {
'Accept': 'application/json',
'Authorization': 'Bearer {Integration_token},
}
response = requests.get(api_url , headers=headers)

The response displayed the following text along with the 403 code, and the correct result value could not be received.

 - The server understood the request, but refused to fulfill it because the access token is missing required scopes or the user is missing required roles or licenses.

Can't APIs be used without a license?

from https://developer.webex.com/docs/api/guides/webex-meetings-rest-api:

"To use the Webex REST API you'll need to be a Webex Meetings subscriber with a Webex account backed by Cisco Webex Common Identity (CI). If you currently use Webex Teams, your account is backed by Common Identity. If you're using only Webex Meetings, your site will need to be on Common Identity."
