Google OAuth 2: response_type error on token request
===

I am trying to return an OAuth 2 response code for an OAuth response token. However, my request returns the following error which has zero results in google. I tried changing `response_type` to "token" instead of "code" but that didn't work either.

> OAuth 2 parameters can only have a single value: response_type

Request Details:

    scope=https://www.googleapis.com/auth/userinfo.email
    client_secret=_____
    response_type=code
    grant_type=authorization_code
    redirect_uri=http://localhost/folder/
    client_id=____.apps.googleusercontent.com
    code=_____

I'm sending this second-step payload to `POST https://accounts.google.com/o/oauth2/auth`

**What is wrong with my request?**
