theauth = HTTPBasicAuth(creds.ClientID,creds.ClientSecret)
client = BackendApplicationClient(creds.ClientID)
bcauth = OAuth2Session(client)
token = bcauth.fetch_token(token_url=tokenendpoint,auth=theauth)

RESPONSE:

"Please supply either code or " "authorization_response parameters."
ValueError: Please supply either code or authorization_response parameters.

NO idea what these mean or why they need to be set for just a Backend Client oAuth.

Putting in :

token = bcauth.fetch_token(token_url=tokenendpoint, client_id=creds.ClientID,client_secret=creds.ClientSecret)

Doesn't work either...

What is going with the documentation?
