Hmm, I meant that the code will check `webhooks` and decide to `GET /groups/<groupid>` or `GET /groups/<groupid>?webhooks=true` depending on its value. It will not leave it un-exercised. It is similar to how otter [implements](https://github.com/rackerlabs/otter/blob/master/otter/models/cass.py#L499) it. Also, I am not sure if `url` needs be an argument. Could you describe where is it being called?
