This is the final object in the OAuth dance - it encapsulates the app,
the endpoint, other parameters and the received credentials. It is a
reference class so that it can be seamlessly updated (e.g. using
$refresh()) when access expires.

An OAuth consumer application, created by

a character vector of scopes to request.
Named list holding endpoint specific parameters to pass to the server when posting the request for obtaining or refreshing the access token.
content type used to override incorrect server response
if FALSE, use a local webserver for the OAuth dance.
Otherwise, provide a URL to the user and prompt for a validation
code. Defaults to the of the "httr_oob_default" default,
or TRUE if httpuv is not installed.
If TRUE, the default, configures the token to add
itself to the bearer header of subsequent requests. If FALSE,
configures the token to add itself as a url parameter of subsequent
requests.
if TRUE use http basic authentication to
retrieve the token. Some authorization servers require this.
If FALSE, the default, retrieve the token by including the
app key and secret in the request body.
A logical value or a string. TRUE means to cache
using the default cache file .httr-oauth, FALSE means
don't cache, and NA means to guess using some sensible heuristics.
A string mean use the specified path as the cache file.
Additional configuration settings sent to
POST, e.g. user_agent.
Default to FALSE. Set to TRUE to use
Client Credentials Grant instead of Authorization
Code Grant. See https://tools.ietf.org/html/rfc6749#section-4.4.
Advanced use only: allows you to completely customise token generation.
A Token2.0 reference class (RC) object.
See Token for full details about the token object, and the
caching policies used to store credentials across sessions.
