OAuth server

General

The OAuth protocol enables web services consumers to access protected resources via an API without requiring users to supply the service credentials to the consumers. It's a generic methodology for unobtrusive, wire protocol level authenticated data access over HTTP.

API

Virtuoso implements the OAuth Core 1.0 specification, and exposes the following API endpoints:

Request token

Endpoint: http://server-cname/OAuth/request_token
