OAuth | Quintype for developers | Bridgekeeper

OAuth 2.0 is an authorization protocol that gives an API client limited access to user data on a web server. It relies on authentication scenarios called flows, which allow the resource owner (user) to share protected content from the resource server without sharing user's credentials. For that purpose, an OAuth 2.0 server issues access tokens which the client applications can use to access protected resources on behalf of the resource owner.
