tda-api: authentication failure

Hey

I’ve created an app on TD Ameritrade with a callback URL https://127.0.0.1:8080 (as suggested on developer pages). I am making sure I am sending the correct API_KEY and redirect_url to the authentication flow

with webdriver.Chrome() as driver:
    c = auth.client_from_login_flow(driver, apikey, redirect_uri, token_path)

However, I am getting the error page a third party application you document.

Logging shows the port on the localhost being sent with the GET is different however
