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.

config_init

Additional configuration settings sent to POST(), e.g. user_agent().
