OpenID Implementation
This document contains technical information for publishers and integrators about OpenID Connect (OIDC) protocol.
- Overview of CONNECT
  CONNECT is an Identity Management as a Service (IDaaS) platform created and managed by Wiley Partner Solutions that enables publishers to securely sign in users to their applications, using the OpenID Connect (OIDC) protocol.
- Overview of OpenID CONNECT
  The OpenID Connect (OIDC) protocol is an extension of OAuth 2.0 for use as an authentication protocol.
- Client Application Configuration
  A client application represents an application (typically a web application) of a publisher that provides services to authenticated users. Each application always belongs to one CONNECT tenant (customer). Each customer can have multiple applications.
- Metadata Document
  The OpenID Connect service is a metadata document that contains most of the information required for a client application to perform the authorization flow. This includes information such as the URLs to use and the location of the service's public signing keys.
- The Authorization Request
  When a web application needs to authenticate a user, it must direct the browser to the URL of the authorization_endpoint, specified in the application metadata. This request is also referred to as the authorization request.
- The id_token
  The id_token can be provided either in JSON format or as a signed JWT (configurable on the CONNECT side according to the client application requirements) and includes basic user profile data that allows the authentication of a user on the client application.
- Automatic Login
  The user authentication status on CONNECT can be checked by an application by issuing a "silent" authorization request.
  - Sample Responses
- Retrieving User Data
  Some applications not only need to sign the user in, but also access a web service on behalf of that user using OAuth. An example of this is a service that provides additional user data than those included in the id_token.

Automatic Login

The user authentication status on CONNECT can be checked by an application by issuing a "silent" authorization request.

This allows users that already have a session with CONNECT and have previously authorized the given application, to automatically log in to the application without a new login challenge.

To implement the silent auto-login, an immediate authorization request is initiated to CONNECT for all new sessions, adding prompt=none in the request parameters as in the following example:

GET https://appname.scienceconnect.io/api/oauth/authorize? 
    client_id=testclient   
    &response_type=id_token 
    &redirect_uri=https://www.appname.com/oidc/cbk 
    &scope=openid 
    &state=jctMTcwMWE1ZmQ2ZTQx 
    &nonce=7362CAEA-9CA5-4B43-9BA3 
    &prompt=none

Adding prompt=none ensures that users return to the application without seeing a CONNECT user interface. Depending on their authentication status and id_token (or code), they either log in automatically or an error is returned to the application immediately.
