High Level OIDC API

Add OpenID provider functionality to your web application with just a few lines of code.

A high-level, configuration-driven OIDC API hides the complexities of OpenID Connect, making for a quick and easy implementation.

Configuration changes, including adding support for additional clients, can be made with zero code updates.

Processing an OpenID Discovery Metadata Request

OpenID metadata is returned to the client.

            
[Route(".well-known/openid-configuration")]
[ResponseCache(Duration = 600, Location = ResponseCacheLocation.Any)]
public async Task GetMetadataAsync()
{
    // Return the OpenID provider's metadata.
    return await _openIDProvider.GetMetadataAsync();
}

Processing an OpenID Key Request

OpenID keys are returned to the client.

            
[Route("openid/keys")]
[ResponseCache(Duration = 600, Location = ResponseCacheLocation.Any)]
public async Task GetKeysAsync()
{
    // Return the OpenID provider's keys.
    return await _openIDProvider.GetKeysAsync();
}

Processing an OpenID Connect Authentication Request

The authorization request is received and processed.

            
[Route("openid/authorize")]
public async Task AuthorizeAsync()
{
    // Receive and process the OpenID Connect authentication request.
    var authenticationRequest = await _openIDProvider.ReceiveAuthnRequestAsync();
}

Sending an OpenID Connect Authentication Response

The authorization response is created and sent.

            
[Route("openid/AuthenticationCompletion")]
public async Task AuthenticationCompletionAsync()
{
    // Create and send the OpenID Connect authentication response.
    return await _openIDProvider.SendAuthnResponseAsync(name, claims, accessToken);
}
