Arguments

endpoint	An OAuth endpoint, created by oauth_endpoint()
app	An OAuth consumer application, created by oauth_app()
scope	a character vector of scopes to request.
user_params	Named list holding endpoint specific parameters to pass to the server when posting the request for obtaining or refreshing the access token.
type	content type used to override incorrect server response
use_oob	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.
oob_value	if provided, specifies the value to use for the redirect_uri parameter when retrieving an authorization URL. Defaults to "urn:ietf:wg:oauth:2.0:oob". Requires use_oob = TRUE.
is_interactive	DEPRECATED
use_basic_auth	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.
config_init	Additional configuration settings sent to POST(), e.g. user_agent().
client_credentials	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.
