from msal import PublicClientApplication

function_app_url = "https://FUNCTION_APP_NAME.azurewebsites.net"

tenant_id = "TENANT_ID"
public_client_app_id = "KATANA_CLIENT_APP_ID"
server_app_id_uri = "api://" + tenant_id + "/cloudkatana"
scope = server_app_id_uri + "/user_impersonation"

app = PublicClientApplication(
    public_client_app_id,
    authority="https://login.microsoftonline.com/" + tenant_id
)
result = app.acquire_token_interactive(scopes=[scope])
bearer_token = result['access_token']

Set Azure Function Orchestrator

endpoint = function_app_url + "/api/orchestrators/Orchestrator"
