!!! Overview
[{$pagename}] defines a specific [API] used by a [OAuth Client] (i.e. [Service Provider]) in order to question an [End-User] ([Resource Owner]) and get his Statement (i.e. his answer). 


The question is a short interrogative sentence (e.g. "Which product do you want to order ?") and the statement (e.g. "the blue one") is selected amongst proposed statements (e.g. "none", "the blue one", "the red one") that are also short texts.

This [API] is specified as an [OAuth 2.0]-protected [Resource Server] accessible with an [Access_token].

The [OAuth Client] can use the [API] defined in this specification whether the End-User is currently using the [OAuth Client] or not.

[{$pagename}] is an [Asynchronous Operation] [API]. There are 2 main ways to get the End-User's Statement: the first one requires some polling of the [API] and the second requires the [OAuth Client] to expose a callback [endpoint].

[{$pagename}] is a [Specification] from the [OpenID Foundation] [Working Group] [Mobile Operator Discovery, Registration & Authentication]
