Configuration.api_key* are not really used

Comienza con Configuration(api_key=...) y el ejemplo de README.md que usa access_token; después, sigue cómo ApiClient autentica AdminApi->admin_apps_list. Reproduce el 403 y verifica que la configuración elegida produzca solicitudes autenticadas; se considera terminado cuando la terminología del token documentada y el comportamiento de configuración operativo sean coherentes.

I got tempted to pass api_key = 'my-super-duper-secret-key' to the Configuration object, as one has an API key at hand, and all I got was a 403 Error (t-shirt material right there).

import os
import sys
import authentik_client


def main():
    host = os.environ.get("AUTHENTIK_HOST") # I passed here a URL ending in "/api/v3" even though is called "host", see #9 
    token = os.environ.get("AUTHENTIK_TOKEN")
    if not token:
        print("AUTHENTIK_TOKEN unset")
        sys.exit(1)

    if not host:
        print("AUTHENTIK_URL unset")
        sys.exit(1)

    configuration = authentik_client.Configuration(
        host=host,
        api_key=token
    )

    with authentik_client.ApiClient(configuration) as api_client:
        # Create an instance of the API class
        api_instance = authentik_client.AdminApi(api_client)
        try:
            api_response = api_instance.admin_apps_list()
            print("The response of AdminApi->admin_apps_list:\n")
            print(api_response)
        except authentik_client.ApiException as e:
            print("Exception when calling AdminApi->admin_apps_list: %s\n" % e)


if __name__ == "__main__":
    main()

When invoking it I got:

python move-okta-app-to-authentik.py 
Exception when calling AdminApi->admin_apps_list: (403)
Reason: Forbidden

In fairness the example in the REAMDE.md points out the usage of access_token, however it doesn't really align with the nomenclature.

# Configure Bearer authorization: authentik
configuration = authentik_client.Configuration(
    access_token = os.environ["BEARER_TOKEN"]
)

But your API Credential to interact with the server is a "Bootstrap token", and for users you can create "Token"'s, (notice the lack of "Access").
