Not using token

[orxobo]

You seem to be sending:
base64.StdEncoding.EncodeToString([]byte( fmt.Sprintf("Basic %s:%s", s.config.ClientID, s.config.ClientSecret)
for each call to the API by adding it to the header from getAuthorisationHeader() for each call.
Is that necessary as the token is automatically sent with the http.Client?
